--- _id: '1923' abstract: - lang: eng text: We derive the equations for a thin, axisymmetric elastic shell subjected to an internal active stress giving rise to active tension and moments within the shell. We discuss the stability of a cylindrical elastic shell and its response to a localized change in internal active stress. This description is relevant to describe the cellular actomyosin cortex, a thin shell at the cell surface behaving elastically at a short timescale and subjected to active internal forces arising from myosin molecular motor activity. We show that the recent observations of cell deformation following detachment of adherent cells (Maître J-L et al 2012 Science 338 253-6) are well accounted for by this mechanical description. The actin cortex elastic and bending moduli can be obtained from a quantitative analysis of cell shapes observed in these experiments. Our approach thus provides a non-invasive, imaging-based method for the extraction of cellular physical parameters. article_number: '065005' author: - first_name: Hélène full_name: Berthoumieux, Hélène last_name: Berthoumieux - first_name: Jean-Léon full_name: Maître, Jean-Léon id: 48F1E0D8-F248-11E8-B48F-1D18A9856A87 last_name: Maître orcid: 0000-0002-3688-1474 - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 - first_name: Ewa full_name: Paluch, Ewa last_name: Paluch - first_name: Frank full_name: Julicher, Frank last_name: Julicher - first_name: Guillaume full_name: Salbreux, Guillaume last_name: Salbreux citation: ama: Berthoumieux H, Maître J-L, Heisenberg C-PJ, Paluch E, Julicher F, Salbreux G.

In plants, cell polarity (re)establishment is intimately linked to patterning processes. Despite the importance of cell polarity, its underlying mechanisms are still largely unknown, including the definition and distinctiveness of the polar domains within the PM. Here, we show in Arabidopsis thaliana that the signaling membrane components, the phosphoinositides phosphatidylinositol 4-phosphate (PtdIns4P) and phosphatidylinositol 4, 5-bisphosphate [PtdIns(4, 5)P2] as well as PtdIns4P 5-kinases mediating their interconversion, are specifically enriched at apical and basal polar plasma membrane domains. The PtdIns4P 5-kinases PIP5K1 and PIP5K2 are redundantly required for polar localization of specifically apical and basal cargoes, such as PIN-FORMED transporters for the plant hormone auxin. As a consequence of the polarity defects, instructive auxin gradients as well as embryonic and postembryonic patterning are severely compromised. Furthermore, auxin itself regulates PIP5K transcription and PtdIns4P and PtdIns(4, 5)P2 levels, in particular their association with polar PM domains. Our results provide insight into the polar domain-delineating mechanisms in plant cells that depend on apical and basal distribution of membrane lipids and are essential for embryonic and postembryonic patterning. acknowledgement: This work was supported by grants from the Odysseus program of the Research Foundation-Flanders (to J.F.). author: - first_name: Ricardo full_name: Tejos, Ricardo last_name: Tejos - first_name: Michael full_name: Sauer, Michael last_name: Sauer - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: 'MiriamPalacios ' full_name: 'Palacios-Gomez, MiriamPalacios ' last_name: Palacios-Gomez - first_name: Hongjiang full_name: Li, Hongjiang id: 33CA54A6-F248-11E8-B48F-1D18A9856A87 last_name: Li orcid: 0000-0001-5039-9660 - first_name: Mareike full_name: Heilmann, Mareike last_name: Heilmann - first_name: Ringo full_name: Van Wijk, Ringo last_name: Van Wijk - first_name: Joop full_name: Vermeer, Joop last_name: Vermeer - first_name: Ingo full_name: Heilmann, Ingo last_name: Heilmann - first_name: Teun full_name: Munnik, Teun last_name: Munnik - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Tejos R, Sauer M, Vanneste S, et al.

Here, we endeavoured to clarify the function of brassinosteroids (BRs) and cross-talk with ethylene in hook development. An automated infrared imaging system was developed to study the kinetics of hook development in etiolated Arabidopsis seedlings. To ascertain the photomorphogenic control of hook opening, the system was equipped with an automatic light dimmer. We demonstrate that ethylene and BRs are indispensable for hook formation and maintenance. Ethylene regulation of hook formation functions partly through BRs, with BR feedback inhibition of ethylene action. Conversely, BR-mediated extension of hook maintenance functions partly through ethylene. Furthermore, we revealed that a short light pulse is sufficient to induce rapid hook opening. Our dynamic infrared imaging system allows high-resolution, kinetic imaging of up to 112 seedlings in a single experimental run. At this high throughput, it is ideally suited to rapidly gain insight in pathway networks. We demonstrate that BRs and ethylene cooperatively regulate apical hook development in a phase-dependent manner. Furthermore, we show that light is a predominant regulator of hook opening, inhibiting ethylene- and BR-mediated postponement of hook opening. acknowledgement: 'Funded by Ghent University; Research Foundation Flanders Grant Number: G065613N European Research Council Grant Number: CZ.1.07/2.3.00/20.0043' author: - first_name: Dajo full_name: Smet, Dajo last_name: Smet - first_name: Petra full_name: Žádníková, Petra last_name: Žádníková - first_name: Filip full_name: Vandenbussche, Filip last_name: Vandenbussche - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Dominique full_name: Van Der Straeten, Dominique last_name: Van Der Straeten citation: ama: 'Smet D, Žádníková P, Vandenbussche F, Benková E, Van Der Straeten D.

(CCS’13), and Boyle et al. (PKC’14). In a standard pseudorandom function (PRF) a key k is used to evaluate the PRF on all inputs in the domain. Constrained PRFs additionally offer the functionality to delegate “constrained” keys kS which allow to evaluate the PRF only on a subset S of the domain. The three above-mentioned papers all show that the classical GGM construction (J.ACM’86) of a PRF from a pseudorandom generator (PRG) directly yields a constrained PRF where one can compute constrained keys to evaluate the PRF on all inputs with a given prefix. This constrained PRF has already found many interesting applications. Unfortunately, the existing security proofs only show selective security (by a reduction to the security of the underlying PRG). To achieve full security, one has to use complexity leveraging, which loses an exponential factor 2N in security, where N is the input length. The first contribution of this paper is a new reduction that only loses a quasipolynomial factor qlog N, where q is the number of adversarial queries. For this we develop a new proof technique which constructs a distinguisher by interleaving simple guessing steps and hybrid arguments a small number of times. This approach might be of interest also in other contexts where currently the only technique to achieve full security is complexity leveraging. Our second contribution is concerned with another constrained PRF, due to Boneh and Waters, which allows for constrained keys for the more general class of bit-fixing functions. Their security proof also suffers from a 2N loss, which we show is inherent. We construct a meta-reduction which shows that any “simple” reduction of full security from a noninteractive hardness assumption must incur an exponential security loss. acknowledgement: We are grateful to Mihir Bellare for his feedback on earlier versions of this paper.

They develop from protodermal cells after unequal divisions followed by an equal division and differentiation. The concentration of the hormone auxin, a master plant developmental regulator, is tightly controlled in time and space, but its role, if any, in stomatal formation is obscure. Here dynamic changes of auxin activity during stomatal development are monitored using auxin input (DII-VENUS) and output (DR5:VENUS) markers by time-lapse imaging. A decrease in auxin levels in the smaller daughter cell after unequal division presages the acquisition of a guard mother cell fate whose equal division produces the two guard cells. Thus, stomatal patterning requires auxin pathway control of stem cell compartment size, as well as auxin depletion that triggers a developmental switch from unequal to equal division. article_number: '3090' author: - first_name: Jie full_name: Le, Jie last_name: Le - first_name: Xuguang full_name: Liu, Xuguang last_name: Liu - first_name: Kezhen full_name: Yang, Kezhen last_name: Yang - first_name: Xiaolan full_name: Chen, Xiaolan last_name: Chen - first_name: Lingling full_name: Zhu, Lingling last_name: Zhu - first_name: Hongzhe full_name: Wang, Hongzhe last_name: Wang - first_name: Ming full_name: Wang, Ming last_name: Wang - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Miyo full_name: Morita, Miyo last_name: Morita - first_name: Masao full_name: Tasaka, Masao last_name: Tasaka - first_name: Zhaojun full_name: Ding, Zhaojun last_name: Ding - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Tom full_name: Beeckman, Tom last_name: Beeckman - first_name: Fred full_name: Sack, Fred last_name: Sack citation: ama: Le J, Liu X, Yang K, et al.

Many models describing competition for hosts between non-interacting pathogen strains in an infinite population lead to the conclusion that selection favors invasion of new strains if and only if they have higher R0 values than the resident. Here we demonstrate that this picture fails in finite populations. Using a simple stochastic SIS model, we show that in general there is no analogous optimization principle. We find that successive invasions may in some cases lead to strains that infect a smaller fraction of the host population, and that mutually invasible pathogen strains exist. In the limit of weak selection we demonstrate that an optimization principle does exist, although it differs from R0 maximization. For strains with very large R0, we derive an expression for this local fitness function and use it to establish a lower bound for the error caused by neglecting stochastic effects. Furthermore, we apply this weak selection limit to investigate the selection dynamics in the presence of a trade-off between the virulence and the transmission rate of a pathogen. acknowledgement: J.H. received support from the Zdenek Bakala Foundation and the Mobility Fund of Charles University in Prague. author: - first_name: Jan full_name: Humplik, Jan id: 2E9627A8-F248-11E8-B48F-1D18A9856A87 last_name: Humplik - first_name: Alison full_name: Hill, Alison last_name: Hill - first_name: Martin full_name: Nowak, Martin last_name: Nowak citation: ama: Humplik J, Hill A, Nowak M.

If the strength J of the ferromagnetic interaction is larger than a critical value J c, then the ground state is homogeneous. It has been conjectured that when J is smaller than but close to J c, the ground state is periodic and striped, with stripes of constant width h = h(J), and h → ∞ as J → Jc -. (In d = 3 stripes mean slabs, not columns.) Here we rigorously prove that, if we normalize the energy in such a way that the energy of the homogeneous state is zero, then the ratio e 0(J)/e S(J) tends to 1 as J → Jc -, with e S(J) being the energy per site of the optimal periodic striped/slabbed state and e 0(J) the actual ground state energy per site of the system. Our proof comes with explicit bounds on the difference e 0(J)-e S(J) at small but positive J c-J, and also shows that in this parameter range the ground state is striped/slabbed in a certain sense: namely, if one looks at a randomly chosen window, of suitable size ℓ (very large compared to the optimal stripe size h(J)), one finds a striped/slabbed state with high probability.' acknowledgement: "2014 by the authors.

It is usually invoked in the context of challenges arising from complex intragroup structures, hierarchies, and alliances. However, a fundamental aspect of group living remains largely unexplored as a driving force in cognitive evolution: the competition between individuals searching for resources (producers) and conspecifics that parasitize their findings (scroungers). In populations of social foragers, abilities that enable scroungers to steal by outsmarting producers, and those allowing producers to prevent theft by outsmarting scroungers, are likely to be beneficial and may fuel a cognitive arms race. Using analytical theory and agent-based simulations, we present a general model for such a race that is driven by the producer-scrounger game and show that the race''s plausibility is dramatically affected by the nature of the evolving abilities. If scrounging and scrounging avoidance rely on separate, strategy-specific cognitive abilities, arms races are short-lived and have a limited effect on cognition. However, general cognitive abilities that facilitate both scrounging and scrounging avoidance undergo stable, long-lasting arms races. Thus, ubiquitous foraging interactions may lead to the evolution of general cognitive abilities in social animals, without the requirement of complex intragroup structures.' author: - first_name: Michal full_name: Arbilly, Michal last_name: Arbilly - first_name: Daniel full_name: Weissman, Daniel id: 2D0CE020-F248-11E8-B48F-1D18A9856A87 last_name: Weissman - first_name: Marcus full_name: Feldman, Marcus last_name: Feldman - first_name: Uri full_name: Grodzinski, Uri last_name: Grodzinski citation: ama: Arbilly M, Weissman D, Feldman M, Grodzinski U.

Cytokinin-mediated modulation of auxin transport provides an efficient means to regulate auxin distribution in plant organs. Here, we demonstrate that cytokinin does not merely control the overall auxin flow capacity, but might also act as a polarizing cue and control the auxin stream directionality during plant organogenesis. Cytokinin enhances the PIN-FORMED1 (PIN1) auxin transporter depletion at specific polar domains, thus rearranging the cellular PIN polarities and directly regulating the auxin flow direction. This selective cytokinin sensitivity correlates with the PIN protein phosphorylation degree. PIN1 phosphomimicking mutations, as well as enhanced phosphorylation in plants with modulated activities of PIN-specific kinases and phosphatases, desensitize PIN1 to cytokinin. Our results reveal conceptually novel, cytokinin-driven polarization mechanism that operates in developmental processes involving rapid auxin stream redirection, such as lateral root organogenesis, in which a gradual PIN polarity switch defines the growth axis of the newly formed organ. author: - first_name: Peter full_name: Marhavy, Peter id: 3F45B078-F248-11E8-B48F-1D18A9856A87 last_name: Marhavy orcid: 0000-0001-5227-5741 - first_name: Jérôme full_name: Duclercq, Jérôme last_name: Duclercq - first_name: Benjamin full_name: Weller, Benjamin last_name: Weller - first_name: Elena full_name: Feraru, Elena last_name: Feraru - first_name: Agnieszka full_name: Bielach, Agnieszka last_name: Bielach - first_name: Remko full_name: Offringa, Remko last_name: Offringa - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Claus full_name: Schwechheimer, Claus last_name: Schwechheimer - first_name: Angus full_name: Murphy, Angus last_name: Murphy - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 citation: ama: Marhavý P, Duclercq J, Weller B, et al.

In standard genetics parlance, these adaptations require the crossing of a wide adaptive valley of deleterious intermediate stages. Here, we demonstrate, using a simple model, that evolution can cross wide valleys to produce "irreducibly complex" adaptations by making use of previously cryptic mutations. When revealed by an evolutionary capacitor, previously cryptic mutants have higher initial frequencies than do new mutations, bringing them closer to a valley-crossing saddle in allele frequency space. Moreover, simple combinatorics implies an enormous number of candidate combinations exist within available cryptic genetic variation. We model the dynamics of crossing of a wide adaptive valley after a capacitance event using both numerical simulations and analytical approximations. Although individual valley crossing events become less likely as valleys widen, by taking the combinatorics of genotype space into account, we see that revealing cryptic variation can cause the frequent evolution of complex adaptations. acknowledgement: "Funded by National Institutes of Health.

Removing this noise is often necessary for efficient analysis and visualization of this data, yet many denoising techniques change the minima and maxima of a scalar field. For example, the extrema can appear or disappear, spatially move, and change their value. This can lead to wrong interpretations of the data, e.g., when the maximum temperature over an area is falsely reported being a few degrees cooler because the denoising method is unaware of these features. Recently, a topological denoising technique based on a global energy optimization was proposed, which allows the topology-controlled denoising of 2D scalar fields. While this method preserves the minima and maxima, it is constrained by the size of the data. We extend this work to large 2D data and medium-sized 3D data by introducing a novel domain decomposition approach. It allows processing small patches of the domain independently while still avoiding the introduction of new critical points. Furthermore, we propose an iterative refinement of the solution, which decreases the optimization energy compared to the previous approach and therefore gives smoother results that are closer to the input. We illustrate our technique on synthetic and real-world 2D and 3D data sets that highlight potential applications. acknowledgement: RTRA Digiteoproject; ERC grant; SNF award; Intel Doctoral Fellowship; MPC-VCC author: - first_name: David full_name: Günther, David last_name: Günther - first_name: Alec full_name: Jacobson, Alec last_name: Jacobson - first_name: Jan full_name: Reininghaus, Jan id: 4505473A-F248-11E8-B48F-1D18A9856A87 last_name: Reininghaus - first_name: Hans full_name: Seidel, Hans last_name: Seidel - first_name: Olga full_name: Sorkine Hornung, Olga last_name: Sorkine Hornung - first_name: Tino full_name: Weinkauf, Tino last_name: Weinkauf citation: ama: Günther D, Jacobson A, Reininghaus J, Seidel H, Sorkine Hornung O, Weinkauf T.

Notch signaling plays a pivotal role in regulating this balance, yet the interaction between signaling and receiving cells remains poorly understood. We have found that numerous nascent neurons and/or intermediate neurogenic progenitors expressing the ligand of Notch retain apical endfeet transiently at the ventricular lumen that form adherens junctions (AJs) with the endfeet of progenitors. Forced detachment of the apical endfeet of those differentiating cells by disrupting AJs resulted in precocious neurogenesis that was preceded by the downregulation of Notch signaling. Both Notch1 and its ligand Dll1 are distributed around AJs in the apical endfeet, and these proteins physically interact with ZO-1, a constituent of the AJ. Furthermore, live imaging of a fluorescently tagged Notch1 demonstrated its trafficking from the apical endfoot to the nucleus upon cleavage. Our results identified the apical endfoot as the central site of active Notch signaling to securely prohibit inappropriate differentiation of neural progenitors. author: - first_name: Jun full_name: Hatakeyama, Jun last_name: Hatakeyama - first_name: Yoshio full_name: Wakamatsu, Yoshio last_name: Wakamatsu - first_name: Akira full_name: Nagafuchi, Akira last_name: Nagafuchi - first_name: Ryoichiro full_name: Kageyama, Ryoichiro last_name: Kageyama - first_name: Ryuichi full_name: Shigemoto, Ryuichi id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 - first_name: Kenji full_name: Shimamura, Kenji last_name: Shimamura citation: ama: Hatakeyama J, Wakamatsu Y, Nagafuchi A, Kageyama R, Shigemoto R, Shimamura K.

Still, we are missing a mechanistic account of how these representations come about. Here we provide a simple explanation for a range of experimental findings, in light of prefrontal circuits adapting to task constraints by reward-dependent learning. In particular, we model a neural network shaped by reward-modulated spike-timing dependent plasticity (r-STDP) and homeostatic plasticity (intrinsic excitability and synaptic scaling). We show that the experimentally-observed neural representations naturally emerge in an initially unstructured circuit as it learns to solve several working memory tasks. These results point to a critical, and previously unappreciated, role for reward-dependent learning in shaping prefrontal cortex activity. acknowledgement: Supported in part by EC MEXT project PLICON and the LOEWE-Program “Neuronal Coordination Research Focus Frankfurt” (NeFF).

However, if extant variation is the result of episodes of positive selection, these genealogies may be incorrect, although this information itself may provide biologically and evolutionary meaningful information. In fact, positive Darwinian selection has been detected in the mitochondrial-encoded subunits that comprise complex I from diverse taxa with seemingly dissimilar bioenergetic life histories, but the functional implications of the selected sites are unknown. Complex I produces roughly 40% of the proton flux that is used to synthesize ATP from ADP, and a functional model based on the high-resolution structure of complex I described a unique biomechanical apparatus for proton translocation. We reported positive selection at sites in this apparatus during the evolution of Pacific salmon, and it appeared this was also the case in published reports from other taxa, but a comparison among studies was difficult because different statistical tests were used to detect selection and oftentimes, specific sites were not reported. Here we review the literature of positive selection in mitochondrial genomes, the statistical tests used to detect selection, and the structural and functional models that are currently available to study the physiological implications of selection. We then search for signatures of positive selection among the coding mitochondrial genomes of 237 species with a common set of tests and verify that the ND5 subunit of complex I is a repeated target of positive Darwinian selection in diverse taxa. We propose a novel hypothesis to explain the results based on their bioenergetic life histories and provide a guide for laboratory and field studies to test this hypothesis. acknowledgement: Funded by University of Alaska Center for Global Change Student Research Cooperative Institute for Alaska Research and the Rasmuson Foundation author: - first_name: Michael full_name: Garvin, Michael R last_name: Garvin - first_name: Joseph full_name: Bielawski, Joseph P last_name: Bielawski - first_name: Leonid A full_name: Leonid Sazanov id: 338D39FE-F248-11E8-B48F-1D18A9856A87 last_name: Sazanov orcid: 0000-0002-0977-7989 - first_name: Anthony full_name: Gharrett, Anthony J last_name: Gharrett citation: ama: Garvin M, Bielawski J, Sazanov LA, Gharrett A.

The lack of NDH-2 in mammalian mitochondria and its essentiality in important bacterial pathogens suggests these enzymes may represent a potential new drug target to combat microbial pathogens. Here, we report the first crystal structure of a bacterial NDH-2 enzyme at 2.5Å resolution from Caldalkalibacillus thermarum. The NDH-2 structure reveals a homodimeric organization that has a unique dimer interface. NDH-2 is localized to the cytoplasmic membrane by two separated C-terminal membrane-anchoring regions that are essential for membrane localization and FAD binding, but not NDH-2 dimerization. Comparison of bacterial NDH-2 with the yeast NADH dehydrogenase (Ndi1) structure revealed non-overlapping binding sites for quinone and NADH in the bacterial enzyme. The bacterial NDH-2 structure establishes a framework for the structure-based design of small-molecule inhibitors. acknowledgement: Funded by Health Research Council of New Zealand Royal Society of New Zealand University of Otago New Zealand Synchrotron Group author: - first_name: Adam full_name: 'Heikal, Adam ' last_name: Heikal - first_name: Yoshio full_name: Nakatani, Yoshio last_name: Nakatani - first_name: Elyse full_name: Dunn, Elyse A last_name: Dunn - first_name: Marion full_name: Weimar, Marion R last_name: Weimar - first_name: Catherine full_name: Day, Catherine last_name: Day - first_name: Edward full_name: Baker, Edward N last_name: Baker - first_name: Shaun full_name: Lott, Shaun J last_name: Lott - first_name: Leonid A full_name: Leonid Sazanov id: 338D39FE-F248-11E8-B48F-1D18A9856A87 last_name: Sazanov orcid: 0000-0002-0977-7989 - first_name: Gregory full_name: Cook, Gregory last_name: Cook citation: ama: 'Heikal A, Nakatani Y, Dunn E, et al.

It couples the transfer of two electrons between NADH and ubiquinone to the translocation of four protons across the membrane. Complex I is an L-shaped assembly formed by the hydrophilic (peripheral) arm, containing all the redox centres performing electron transfer and the membrane arm, containing proton-translocating machinery. Mitochondrial complex I consists of 44 subunits of about 1 MDa in total, whilst the prokaryotic enzyme is simpler and generally consists of 14 conserved “core” subunits. Recently we have determined the first atomic structure of the entire complex I, using the enzyme from Thermus thermophilus (536 kDa, 16 subunits, 9 Fe-S clusters, 64 TM helices). Structure suggests a unique coupling mechanism, with redox energy of electron transfer driving proton translocation via long-range (up to ~200 Å) conformational changes. It resembles a steam engine, with coupling elements (akin to coupling rods) linking parts of this molecular machine. author: - first_name: Leonid A full_name: Leonid Sazanov id: 338D39FE-F248-11E8-B48F-1D18A9856A87 last_name: Sazanov orcid: 0000-0002-0977-7989 citation: ama: Sazanov LA.

We developed a cell-free system to recapitulate cytokinesis signaling using cytoplasmic extract from Xenopus eggs. Microtubules grew out as asters from artificial centrosomes and met to organize antiparallel overlap zones. These zones blocked the interpenetration of neighboring asters and recruited cytokinesis midzone proteins, including the chromosomal passenger complex (CPC) and centralspindlin. The CPC was transported to overlap zones, which required two motor proteins, Kif4A and a Kif20A paralog. Using supported lipid bilayers to mimic the plasma membrane, we observed the recruitment of cleavage furrow markers, including an active RhoA reporter, at microtubule overlaps. This system opens further approaches to understanding the biophysics of cytokinesis signaling. acknowledgement: 'This work was supported by NIH grant GM39565 (T.J.M.); MBL fellowships from the Evans Foundation, MBL Associates, and the Colwin Fund (T.J.M. and C.M.F.); HFSP fellowship LT000466/2012-L (M.L.); and NIH grant GM103785 (M.W.).
