However, the molecular mechanisms underlying NLR activation and the subsequent provocation of immune responses are only partially characterized. To identify negative regulators of NLR-mediated immunity, a forward genetic screen was undertaken to search for enhancers of the dwarf, autoimmune gain-of-function snc1 mutant. To avoid lethality resulting from severe dwarfism, the screen was conducted using mos4 (modifier of snc1, 4) snc1 plants, which display wild-type-like morphology and resistance. M2 progeny were screened for mutant, snc1-enhancing (muse) mutants displaying a reversion to snc1-like phenotypes. The muse9 mos4 snc1 triple mutant was found to exhibit dwarf morphology, elevated expression of the pPR2-GUS defense marker reporter gene and enhanced resistance to the oomycete pathogen Hyaloperonospora arabidopsidis Noco2. Via map-based cloning and Illumina sequencing, it was determined that the muse9 mutation is in the gene encoding the SWI/SNF chromatin remodeler SYD (SPLAYED), and was thus renamed syd-10. The syd-10 single mutant has no observable alteration from wild-type-like resistance, although the syd-4 T-DNA insertion allele displays enhanced resistance to the bacterial pathogen Pseudomonas syringae pv. maculicola ES4326. Transcription of SNC1 is increased in both syd-4 and syd-10. These data suggest that SYD plays a subtle, specific role in the regulation of SNC1 expression and SNC1-mediated immunity. SYD may work with other proteins at the chromatin level to repress SNC1 transcription; such regulation is important for fine-tuning the expression of NLR-encoding genes to prevent unpropitious autoimmunity. acknowledgement: "This work was supported by the National Sciences and Engineering Research Council of Canada [Canada Graduate\r\nScholarship–Doctoral to K.J.; Discovery Grant to X.L.]; the department of Botany at the University of f British Columbia\r\n[the Dewar Cooper Memorial Fund to X.L.].The authors would like to thank Dr. Yuelin Zhang and Ms. Yan Li for their assistance with next-generation sequencing, and Mr. Charles Copeland for critical reading of the manuscript." article_processing_charge: No article_type: original author: - first_name: Kaeli C.M. full_name: Johnson, Kaeli C.M. last_name: Johnson - first_name: Shitou full_name: Xia, Shitou last_name: Xia - first_name: Xiaoqi full_name: Feng, Xiaoqi id: e0164712-22ee-11ed-b12a-d80fcdf35958 last_name: Feng orcid: 0000-0002-4008-1234 - first_name: Xin full_name: Li, Xin last_name: Li citation: ama: Johnson KCM, Xia S, Feng X, Li X.

Although such confined spaces can be found in various nanostructured materials, such as zeolites, nanoporous organic frameworks and colloidal nanocrystal assemblies, the slow diffusion of molecules in and out of these materials has greatly hampered studying the effect of confinement on their physicochemical properties. Here, we show that this diffusion limitation can be overcome by reversibly creating and destroying confined environments by means of ultraviolet and visible light irradiation. We use colloidal nanocrystals functionalized with light-responsive ligands that readily self-assemble and trap various molecules from the surrounding bulk solution. Once trapped, these molecules can undergo chemical reactions with increased rates and with stereoselectivities significantly different from those in bulk solution. Illumination with visible light disassembles these nanoflasks, releasing the product in solution and thereby establishes a catalytic cycle. These dynamic nanoflasks can be useful for studying chemical reactivities in confined environments and for synthesizing molecules that are otherwise hard to achieve in bulk solution. article_processing_charge: No article_type: original author: - first_name: Hui full_name: Zhao, Hui last_name: Zhao - first_name: Soumyo full_name: Sen, Soumyo last_name: Sen - first_name: T. full_name: Udayabhaskararao, T. last_name: Udayabhaskararao - first_name: Michał full_name: Sawczyk, Michał last_name: Sawczyk - first_name: Kristina full_name: Kučanda, Kristina last_name: Kučanda - first_name: Debasish full_name: Manna, Debasish last_name: Manna - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Ji-Woong full_name: Lee, Ji-Woong last_name: Lee - first_name: Petr full_name: Král, Petr last_name: Král - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Zhao H, Sen S, Udayabhaskararao T, et al.

However, all the systems described to date are based on nanoparticles (NPs) that are inherently photoresponsive, which makes their preparation cumbersome and can markedly hamper their performance. Here we describe a conceptually new methodology to assemble NPs reversibly using light that does not require the particles to be functionalized with light-responsive ligands. Our strategy is based on the use of a photoswitchable medium that responds to light in such a way that it modulates the interparticle interactions. NP assembly proceeds quantitatively and without apparent fatigue, both in solution and in gels. Exposing the gels to light in a spatially controlled manner allowed us to draw images that spontaneously disappeared after a specific period of time. article_processing_charge: No article_type: original author: - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Dipak full_name: Samanta, Dipak last_name: Samanta - first_name: Ron full_name: Leizrowice, Ron last_name: Leizrowice - first_name: Baruch full_name: Margulis, Baruch last_name: Margulis - first_name: Hui full_name: Zhao, Hui last_name: Zhao - first_name: Martin full_name: Börner, Martin last_name: Börner - first_name: T. full_name: Udayabhaskararao, T. last_name: Udayabhaskararao - first_name: Debasish full_name: Manna, Debasish last_name: Manna - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Kundu PK, Samanta D, Leizrowice R, et al.

Herein we show that by decorating the surfaces of metallic nanoparticles with differently substituted azobenzenes, it is possible to modulate the wavelength of light at which the self-assembly of these nanoparticles is induced. Exposing a mixture of two types of nanoparticles, each functionalized with a different azobenzene, to UV or blue light induces the selective self-assembly of only one type of nanoparticles. Irradiation with the other wavelength triggers the disassembly of the aggregates, and the simultaneous self-assembly of nanoparticles of the other type. By placing both types of azobenzenes on the same nanoparticles, we created unique materials (“frustrated” nanoparticles) whose self-assembly is induced irrespective of the wavelength of the incident light. article_processing_charge: No article_type: original author: - first_name: Debasish full_name: Manna, Debasish last_name: Manna - first_name: Thumu full_name: Udayabhaskararao, Thumu last_name: Udayabhaskararao - first_name: Hui full_name: Zhao, Hui last_name: Zhao - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Manna D, Udayabhaskararao T, Zhao H, Klajn R.

Therefore, control of the chromophore density is essential for enhancing and manipulating the photoisomerization yield. We systematically compare two methods to achieve this goal: First, we assemble monocomponent azobenzene–alkanethiolate SAMs on gold nanoparticles of varying size. Second, we form mixed SAMs of azobenzene–alkanethiolates and “dummy” alkanethiolates on planar substrates. Both methods lead to a gradual decrease of the chromophore density and enable efficient photoswitching with low-power light sources. X-ray spectroscopy reveals that coadsorption from solution yields mixtures with tunable composition. The orientation of the chromophores with respect to the surface normal changes from a tilted to an upright position with increasing azobenzene density. For both systems, optical spectroscopy reveals a pronounced excitonic shift that increases with the chromophore density. In spite of exciting the optical transition of the monomer, the main spectral change in mixed SAMs occurs in the excitonic band. In addition, the photoisomerization yield decreases only slightly by increasing the azobenzene–alkanethiolate density, and we observed photoswitching even with minor dilutions. Unlike in solution, azobenzene in the planar SAM can be switched back almost completely by optical excitation from the cis to the original trans state within a short time scale. These observations indicate cooperativity in the photoswitching process of mixed SAMs.' article_processing_charge: No article_type: original author: - first_name: Thomas full_name: Moldt, Thomas last_name: Moldt - first_name: Daniel full_name: Brete, Daniel last_name: Brete - first_name: Daniel full_name: Przyrembel, Daniel last_name: Przyrembel - first_name: Sanjib full_name: Das, Sanjib last_name: Das - first_name: Joel R. full_name: Goldman, Joel R. last_name: Goldman - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Cornelius full_name: Gahl, Cornelius last_name: Gahl - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Martin full_name: Weinelt, Martin last_name: Weinelt citation: ama: Moldt T, Brete D, Przyrembel D, et al.

However, relatively little attention has been devoted to how the shape and surface chemistry of magnetic nanoparticles affects their self-assembly properties. Here, we undertook a combined experiment–theory study aimed at better understanding of the self-assembly of cubic magnetite (Fe3O4) particles. We demonstrated that, depending on the experimental parameters, such as the direction of the magnetic field and nanoparticle density, a variety of superstructures can be obtained, including one-dimensional filaments and helices, as well as C-shaped assemblies described here for the first time. Furthermore, we functionalized the surfaces of the magnetic nanocubes with light-sensitive ligands. Using these modified nanoparticles, we were able to achieve orthogonal control of self-assembly using a magnetic field and light. article_processing_charge: No article_type: original author: - first_name: Gurvinder full_name: Singh, Gurvinder last_name: Singh - first_name: Henry full_name: Chan, Henry last_name: Chan - first_name: T. full_name: Udayabhaskararao, T. last_name: Udayabhaskararao - first_name: Elijah full_name: Gelman, Elijah last_name: Gelman - first_name: Davide full_name: Peddis, Davide last_name: Peddis - first_name: Artem full_name: Baskin, Artem last_name: Baskin - first_name: Gregory full_name: Leitus, Gregory last_name: Leitus - first_name: Petr full_name: Král, Petr last_name: Král - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Singh G, Chan H, Udayabhaskararao T, et al.

Recently, choosing the nitric oxide molecule as an example, we have introduced and demonstrated an experimental approach to measure coupled valence electronic and rotational wave packets using high-order-harmonic-generation (HHG) spectroscopy [Kraus et al., Phys. Rev. Lett. 111, 243005 (2013)]. A short outline of the theory to describe the combination of the pump and HHG probe process was published together with an extensive discussion of experimental results [Baykusheva et al., Faraday Discuss. 171, 113 (2014)]. The comparison of theory and experiment showed good agreement on a quantitative level. Here, we present the theory in detail, which is based on a generalized density-matrix approach that describes the pump process and the subsequent probing of the wave packets by a semiclassical quantitative rescattering approach. An in-depth analysis of the different Raman scattering contributions to the creation of the coupled rotational and electronic spin-orbit wave packets is made. We present results for parallel and perpendicular linear polarizations of the pump and probe laser pulses. Furthermore, an analysis of the combined rotational-electronic density matrix in terms of irreducible components is presented that facilitates interpretation of the results. article_number: '023421' article_processing_charge: No article_type: original author: - first_name: Song Bin full_name: Zhang, Song Bin last_name: Zhang - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: Peter M. full_name: Kraus, Peter M. last_name: Kraus - first_name: Hans Jakob full_name: Wörner, Hans Jakob last_name: Wörner - first_name: Nina full_name: Rohringer, Nina last_name: Rohringer citation: ama: Zhang SB, Baykusheva DR, Kraus PM, Wörner HJ, Rohringer N.
