This regulation is achieved by different mechanisms, including auxin biosynthesis, metabolic conversions, degradation, and transport. Here, we introduce cis-cinnamic acid (c-CA) as a novel and unique addition to a small group of endogenous molecules affecting in planta auxin concentrations. c-CA is the photo-isomerization product of the phenylpropanoid pathway intermediate trans-CA (t-CA). When grown on c-CA-containing medium, an evolutionary diverse set of plant species were shown to exhibit phenotypes characteristic for high auxin levels, including inhibition of primary root growth, induction of root hairs, and promotion of adventitious and lateral rooting. By molecular docking and receptor binding assays, we showed that c-CA itself is neither an auxin nor an anti-auxin, and auxin profiling data revealed that c-CA does not significantly interfere with auxin biosynthesis. Single cell-based auxin accumulation assays showed that c-CA, and not t-CA, is a potent inhibitor of auxin efflux. Auxin signaling reporters detected changes in spatiotemporal distribution of the auxin response along the root of c-CA-treated plants, and long-distance auxin transport assays showed no inhibition of rootward auxin transport. Overall, these results suggest that the phenotypes of c-CA-treated plants are the consequence of a local change in auxin accumulation, induced by the inhibition of auxin efflux. This work reveals a novel mechanism how plants may regulate auxin levels and adds a novel, naturally occurring molecule to the chemical toolbox for the studies of auxin homeostasis.","lang":"eng"}],"intvolume":" 173","month":"01","scopus_import":"1","language":[{"iso":"eng"}],"file":[{"content_type":"application/pdf","access_level":"open_access","relation":"main_file","file_id":"7040","checksum":"fd4d1cfe7ed70e54bb12ae3881f3fb91","date_updated":"2020-07-14T12:44:36Z","file_size":4109142,"creator":"dernst","date_created":"2019-11-18T16:12:25Z","file_name":"2016_PlantPhysi_Steenackers.pdf"}],"publication_status":"published","publication_identifier":{"issn":["0032-0889"]},"ec_funded":1,"volume":173,"issue":"1"},{"file_date_updated":"2020-07-14T12:44:37Z","department":[{"_id":"NiBa"}],"ddc":["576"],"date_updated":"2023-09-20T11:24:21Z","status":"public","pubrep_id":"727","type":"journal_article","_id":"1169","issue":"1","volume":205,"ec_funded":1,"file":[{"checksum":"7c8ab79cda1f92760bbbbe0f53175bfc","file_id":"4833","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_name":"IST-2016-727-v1+1_SFC_Genetics_final.pdf","date_created":"2018-12-12T10:10:43Z","file_size":361500,"date_updated":"2020-07-14T12:44:37Z","creator":"system"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["00166731"]},"publication_status":"published","month":"01","intvolume":" 205","scopus_import":"1","oa_version":"Submitted Version","abstract":[{"lang":"eng","text":"Dispersal is a crucial factor in natural evolution, since it determines the habitat experienced by any population and defines the spatial scale of interactions between individuals. There is compelling evidence for systematic differences in dispersal characteristics within the same population, i.e., genotype-dependent dispersal. The consequences of genotype-dependent dispersal on other evolutionary phenomena, however, are poorly understood. In this article we investigate the effect of genotype-dependent dispersal on spatial gene frequency patterns, using a generalization of the classical diffusion model of selection and dispersal. Dispersal is characterized by the variance of dispersal (diffusion coefficient) and the mean displacement (directional advection term). We demonstrate that genotype-dependent dispersal may change the qualitative behavior of Fisher waves, which change from being “pulled” to being “pushed” wave fronts as the discrepancy in dispersal between genotypes increases. The speed of any wave is partitioned into components due to selection, genotype-dependent variance of dispersal, and genotype-dependent mean displacement. We apply our findings to wave fronts maintained by selection against heterozygotes. Furthermore, we identify a benefit of increased variance of dispersal, quantify its effect on the speed of the wave, and discuss the implications for the evolution of dispersal strategies."}],"title":"Spatial gene frequency waves under genotype dependent dispersal","publist_id":"6188","author":[{"full_name":"Novak, Sebastian","orcid":"0000-0002-2519-824X","last_name":"Novak","first_name":"Sebastian","id":"461468AE-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Kollár","full_name":"Kollár, Richard","first_name":"Richard"}],"external_id":{"isi":["000393677300025"]},"article_processing_charge":"No","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"chicago":"Novak, Sebastian, and Richard Kollár. “Spatial Gene Frequency Waves under Genotype Dependent Dispersal.” Genetics.

However, when a symmetry-breaking transverse magnetic field is present, all flow states exhibit stimulated, finite two-fold mode. Various bifurcations between steady and unsteady states can occur, corresponding to the transitions between the two-cell and one-cell states. While unsteady, axially oscillating flow states can arise, we also detect the emergence of new unsteady flow states. In particular, we uncover two new states: one contains only the azimuthally oscillating solution in the configuration of the twin-cell flow state, and an-other a rotating flow state. Topologically, these flow states are a limit cycle and a quasiperiodic solution on a two-torus, respectively. Emergence of new flow states in addition to observed ones with classical fluid, indicates that richer but potentially more controllable dynamics in ferrofluidic flows, as such flow states depend on the external magnetic field."}],"month":"01","intvolume":" 7","scopus_import":"1","ddc":["532"],"date_updated":"2023-09-20T11:28:49Z","file_date_updated":"2020-07-14T12:44:36Z","department":[{"_id":"BjHo"}],"_id":"1160","status":"public","pubrep_id":"743","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"day":"06","publication":"Scientific Reports","isi":1,"has_accepted_license":"1","year":"2017","date_published":"2017-01-06T00:00:00Z","doi":"10.1038/srep40012","date_created":"2018-12-11T11:50:28Z","quality_controlled":"1","publisher":"Nature Publishing Group","oa":1,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"ista":"Altmeyer S, Do Y, Lai Y. 2017.

One of the pivotal challenges in this field is the designation of a consistent interpretation framework within which we can describe quantitatively the universal features of those systems. Here we analyze in a detailed manner the principal experimental data and compare them quantitatively with the approach based on a single-band model of strongly correlated electrons supplemented with strong antiferromagnetic (super)exchange interaction (the so-called t−J−U model). The model rationale is provided by estimating its microscopic parameters on the basis of the three-band approach for the Cu-O plane. We use our original full Gutzwiller wave-function solution by going beyond the renormalized mean-field theory (RMFT) in a systematic manner. Our approach reproduces very well the observed hole doping (δ) dependence of the kinetic-energy gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer features of the cuprates. The calculated Fermi velocity in the nodal direction is practically δ-independent and its universal value agrees very well with that determined experimentally. Also, a weak doping dependence of the Fermi wave vector leads to an almost constant value of the effective mass in a pure superconducting phase which is both observed in experiment and reproduced within our approach. An assessment of the currently used models (t−J, Hubbard) is carried out and the results of the canonical RMFT as a zeroth-order solution are provided for comparison to illustrate the necessity of the introduced higher-order contributions."}],"oa_version":"Submitted Version","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1606.03247"}],"scopus_import":"1","intvolume":" 95","month":"01","publication_status":"published","publication_identifier":{"issn":["24699950"]},"language":[{"iso":"eng"}],"ec_funded":1,"issue":"2","volume":95,"_id":"1162","type":"journal_article","status":"public","date_updated":"2023-09-20T11:25:56Z","department":[{"_id":"MiLe"}],"oa":1,"publisher":"American Physical Society","quality_controlled":"1","year":"2017","isi":1,"publication":"Physical Review B - Condensed Matter and Materials Physics","day":"13","date_created":"2018-12-11T11:50:29Z","doi":"10.1103/PhysRevB.95.024506","date_published":"2017-01-13T00:00:00Z","article_number":"024506","project":[{"grant_number":"291734","name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"}],"citation":{"chicago":"Spałek, Jozef, Michał Zegrodnik, and Jan Kaczmarczyk. “Universal Properties of High Temperature Superconductors from Real Space Pairing T-J-U Model and Its Quantitative Comparison with Experiment.” Physical Review B - Condensed Matter and Materials Physics.

The special type of selection operator prefers the coherent alternative solutions, eliminating artifacts appearing in the particular processes. The additional accuracy increment is obtained by the parallel convex searches applied to the local scalarizations of the misfit vector. The strategy is dedicated for solving ill-conditioned problems, for which inverting the single physical process can lead to the ambiguous results. The skill of the selection in artifact elimination is shown on the benchmark problem, while the whole strategy was applied for identification of oil deposits, where the misfits are related to various frequencies of the magnetic and electric waves of the magnetotelluric measurements. 2016 Elsevier B.V.","lang":"eng"}],"oa_version":"Submitted Version","scopus_import":"1","month":"01","intvolume":" 18","publication_identifier":{"issn":["18777503"]},"publication_status":"published","file":[{"relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"file_id":"5842","creator":"dernst","file_size":1083911,"date_updated":"2019-01-18T08:43:16Z","file_name":"2016_jocs_ewa.pdf","date_created":"2019-01-18T08:43:16Z"}],"language":[{"iso":"eng"}],"volume":18,"_id":"1152","type":"journal_article","status":"public","date_updated":"2023-09-20T11:29:44Z","ddc":["000"],"department":[{"_id":"ChWo"}],"file_date_updated":"2019-01-18T08:43:16Z"},{"language":[{"iso":"eng"}],"file":[{"creator":"system","file_size":56664,"date_updated":"2020-07-14T12:44:37Z","file_name":"IST-2017-739-v1+2_10260_2016_375_MOESM1_ESM.pdf","date_created":"2018-12-12T10:16:13Z","relation":"main_file","access_level":"open_access","content_type":"application/pdf","checksum":"0b2d1b647ca96e9ef13a14b8b6775e0f","file_id":"5199"},{"file_id":"5200","checksum":"3321ef34e02e28acfc427f77cf32812a","content_type":"application/pdf","access_level":"open_access","relation":"main_file","date_created":"2018-12-12T10:16:14Z","file_name":"IST-2017-739-v1+3_s10260-016-0375-6.pdf","date_updated":"2020-07-14T12:44:37Z","file_size":688953,"creator":"system"}],"publication_status":"published","volume":26,"issue":"3","oa_version":"Submitted Version","abstract":[{"lang":"eng","text":"Optimum experimental design theory has recently been extended for parameter estimation in copula models.

In this work, we treat this problem with the application of the (Formula presented.)-optimality to copula models. First, we provide an extension of the corresponding equivalence theory.

Both terms lead to a pronounced asymmetry of the superconducting order parameter. The next-to-nearest neighbor hopping enhances superconductivity for h-doping, while diminishes it for e-doping. The charge-bond interaction alone leads to the opposite effect and, additionally, to the kinetic-energy gain upon condensation in the underdoped regime. With both terms included, with similar amplitudes, the height of the superconducting dome and the critical doping remain in favor of h-doping.
