The root hair is a model system for understanding plant cell tip growth. As phosphatidylinositol 3-phosphate [PtdIns(3)P] has been shown in other types to regulate factors that affect growth, including reactive oxygen species (ROS) levels, cytoskeleton, and endosomal movement, we hypothesized PtdIns(3)P also important elongation. enzyme generates PtdIns(3)P, 3-kinase (PI3K), was expressed cells of transgenic plants containing the PI3K promoter:β-glucuronidase reporter construct. To obtain...
Abstract Rapid stomatal closure is essential for water conservation in plants and thus critical survival under deficiency. To close stomata rapidly, guard cells reduce their volume by converting a large central vacuole into highly convoluted structure. However, the molecular mechanisms underlying this change are poorly understood. In study, we used pH-indicator dyes to demonstrate that vacuolar convolution accompanied acidification of fava bean (Vicia faba) during abscisic acid (ABA)–induced...
Abstract Protection against microbial pathogens involves the activation of cellular immune responses in eukaryotes, and this immunity likely changes subcellular membrane trafficking. In members Rab GTPase family small monomeric regulatory GTPases play prominent roles regulation We previously showed that RabA4B is recruited to vesicles emerge from trans-Golgi network (TGN) compartments regulates polarized trafficking plant cells. As part regulation, recruits closely related...
In plants, changes in cell size and shape during development fundamentally depend on the ability to synthesize modify wall polysaccharides. The main classes of polysaccharides produced by terrestrial plants are cellulose, hemicelluloses, pectins. Members cellulose synthase (CESA) synthase-like (CSL) families encode glycosyltransferases that β-1,4-linked glycan backbones most hemicellulosic comprise plant walls. Cellulose microfibrils major load-bearing component walls assembled from...
Abstract Activation of plasma membrane (PM) H+-ATPase activity is crucial in guard cells to promote light-stimulated stomatal opening, and growing organs cell expansion. In organs, SMALL AUXIN UP RNA (SAUR) proteins inhibit the PP2C.D2, PP2C.D5, PP2C.D6 (PP2C.D2/5/6) phosphatases, thereby preventing dephosphorylation penultimate phosphothreonine PM H+-ATPases trapping them activated state To elucidate whether SAUR–PP2C.D regulatory modules also affect reversible expansion, we examined...
