Significance The function of the cell membrane as a barrier and matrix for biochemical activity relies on properties imparted by lipids. In eukaryotes, sterols are crucial modulating molecular order membranes. Sterol ordering provides basis lateral segregation promotes fluid, mechanically robust plasma membrane. How do organisms that lack determine order? Hopanoids bacterial lipids have been demonstrated to sterol-like in vitro. We now explore distribution hopanoids their effect membranes...
Mechanical stimuli, such as wind, rain, and touch affect plant development, growth, pest resistance, ultimately reproductive success. Using water spray to simulate we demonstrate that jasmonic acid (JA) signaling plays a key role in early gene-expression changes, well before it leads developmental changes flowering architecture. The JA-activated transcription factors MYC2/MYC3/MYC4 modulate transiently induced expression of 266 genes, most which peak within 30 min, control 52% genes...
Plants respond to mechanical stimuli direct their growth and counteract environmental threats. Mechanical stimulation triggers rapid gene expression changes affects plant appearance (thigmomorphogenesis) flowering. Previous studies reported the importance of jasmonic acid (JA) in touch signaling. Here, we used reverse genetics further characterize molecular mechanisms underlying We show that Piezo mechanosensitive ion channels have no major role touch-induced thigmomorphogenesis. In...
Abstract Recent studies in Arabidopsis (Arabidopsis thaliana) have reported conflicting roles for NAC DOMAIN CONTAINING PROTEIN 17 (ANAC017), a transcription factor regulating mitochondria-to-nuclear signaling, and its closest paralog 16 (ANAC016), leaf senescence. By synchronizing senescence individually darkened leaves of knockout overexpressing mutants from these contrasting studies, we demonstrate that elevated ANAC017 expression consistently causes accelerated cell death. A...
Because of their symbiotic origin, many mitochondrial proteins are well conserved across eukaryotic kingdoms. It is however less obvious how specific lineages have obtained novel nuclear-encoded proteins. Here, we report a case neofunctionalization in plants. Phylogenetic analysis genes containing the Domain Unknown Function 295 (DUF295) revealed that domain likely originated Angiosperms. The C-terminal DUF295 usually accompanied by an N-terminal F-box domain, involved ubiquitin ligation via...
Abstract Identification of autophagic protein cargo in plants autophagy-related genes (ATG) mutants is complicated by changes synthesis and degradation. To detect cargo, we measured degradation rate shoots roots Arabidopsis (Arabidopsis thaliana) atg5 atg11 mutants. These data show that less than a quarter proteins changing abundance are probable revealed roles ATG11 ATG5 specific glycolytic enzymes other cytosol, chloroplast, ER-resident proteins, specialized role for from mitochondria...
Abstract Identification of autophagic protein cargo in plants by their abundance autophagy related genes ( ATG ) mutants is complicated changes both synthesis and degradation. To detect cargo, we measured degradation rate shoots roots Arabidopsis atg5 atg11 mutant plants. These data show that less than a quarter proteins changing are probable revealed roles ATG11 ATG5 specific cytosol, chloroplast ER-resident proteins, specialized role for from mitochondria chloroplasts.
