In plants, cell proliferation and polarized differentiation along the adaxial–abaxial axis in primordium is critical for leaf morphogenesis, while temporal–spatial relationships between these two processes remain largely unexplored. Here, it reported that microRNA396 (miR396)-targeted Arabidopsis growth-regulating factors (AtGRFs) are required polarity Arabidopsis. Reduction of expression AtGRF genes by transgenic miR396 overexpression mutants asymmetric leaves1 (as1) as2 resulted plants...
As well as their importance to nutrition, fatty acids (FA) represent a unique group of quorum sensing chemicals that modulate the behavior bacterial population in virulence. However, way which full-length, membrane-bound receptors biochemically detect FA remains unclear. Here, we provide genetic, enzymological and biophysical evidences demonstrate phytopathogenic bacterium Xanthomonas campestris pv. campestris, medium-chain diffusible signal factor (DSF) binds directly N-terminal, 22 amino...
Both iron starvation and excess are detrimental to cellular life, especially for animal plant pathogens since they always live in iron-limited environments produced by host immune responses. However, how organisms sense respond is incompletely understood. Herein, we reveal that the phytopathogenic bacterium Xanthomonas campestris pv. campestris, VgrS (also named ColS) a membrane-bound receptor histidine kinase senses extracytoplasmic limitation periplasm, while its cognate response...
Abstract Endoreduplication, a process in which DNA replication occurs the absence of mitosis, is found all eukaryotic kingdoms, especially plants, where it assumed to be important for cell growth and fate maintenance. However, comprehensive understanding mechanism regulating endoreduplication still lacking. We previously reported that UBIQUITIN-SPECIFIC PROTEASE14 (UBP14), encoded by DA3, acts upstream CYCLIN-DEPENDENT KINASE B1;1 (CDKB1;1) influence Arabidopsis thaliana. The da3-1 mutant...
In bacterial cells, histidine kinases (HKs) are receptors that monitor environmental and intracellular stimuli. HKs their cognate response regulators constitute two-component signalling systems (TCSs) modulate cellular homeostasis through reversible protein phosphorylation. Here the authors show plant pathogen Xanthomonas campestris pv. responds to osmostress conditions by regulating activity of a HK (VgrS) via irreversible, proteolytic modification. This regulation is mediated periplasmic,...
Summary During adaptation to environments, bacteria employ two‐component signal transduction systems, which contain histidine kinases and response regulators, sense respond exogenous cellular stimuli in an accurate spatio‐temporal manner. Although the protein phosphorylation process between kinase regulator has been well documented, molecular mechanism fine‐tuning levels of regulators is comparatively less studied. Here we combined genetic biochemical approaches reveal that a hybrid kinase,...
PDZ domain–containing proteases, also known as HtrA family play important roles in bacterial cells by modulating disease pathogenesis and cell-envelope stress responses. These proteases have diverse functions through proteolysis- nonproteolysis-dependent modes. Here, we report that the genome of causative agent rice blight, Xanthomonas oryzae pv. oryzae, encodes seven proteins. Systematic inactivation their encoding genes revealed PXO_01122 PXO_04290 (prc) are involved virulence. prc a...
Abstract Chemical signal‐mediated biological communication is common within bacteria and between their hosts. Many plant‐associated respond to unknown plant compounds regulate bacterial gene expression. However, the nature of that mediate such interkingdom underlying mechanisms remain poorly characterized. Xanthomonas campestris pv. (Xcc) causes black rot disease on brassica vegetables. Xcc contains an orphan LuxR regulator (XccR) which senses a signal was validated be glucose by HPLC‐MS....
How essential, regulatory genes originate and evolve is intriguing because mutations of these not only lead to lethality in organisms, but also have pleiotropic effects since they control the expression multiple downstream genes. Therefore, evolution determined by genetic variations their own sequences, biological function molecular mechanisms regulation. To understand origin genes, experimental dissection complete cascade needed. Here, we provide evidences reveal that PhoP-PhoQ an essential...
