Diversification of Root Hair Development Genes in Vascular Plants.
The molecular genetic program for root hair development has been studied intensively in Arabidopsis (Arabidopsis thaliana). To understand the extent to which this program might operate in other plants, we conducted a large-scale comparative analysis of root hair development genes from diverse vascular plants, including eudicots, monocots, and a lycophyte. Combining phylogenetics and transcripto...
متن کاملAbscisic Acid Regulates Auxin Homeostasis in Rice Root Tips to Promote Root Hair Elongation
Abscisic acid (ABA) plays an essential role in root hair elongation in plants, but the regulatory mechanism remains to be elucidated. In this study, we found that exogenous ABA can promote rice root hair elongation. Transgenic rice overexpressing SAPK10 (Stress/ABA-activated protein kinase 10) had longer root hairs; rice plants overexpressing OsABIL2 (OsABI-Like 2) had attenuated ABA signaling ...
متن کاملHomology-dependent Gene Silencing in Plants.
Homology-dependent gene silencing phenomena in plants have received considerable attention, especially when it was discovered that the presence of homologous sequences not only affected the stability of transgene expression, but that the activity of endogenous genes could be altered after insertion of homologous transgenes into the genome. Homology-mediated inactivation most likely comprises at...
متن کاملDiaphanous-related Formin homology proteins
What are Diaphanous-related Formin homology (DRF) proteins? DRF proteins constitute a subfamily of Rho GTPase-binding Formin homology (FH) proteins, first defined after the discovery of conserved FH1 and FH2 domains shared between Diaphanous and Bni1p, required for cytokinesis in flies and yeast, respectively, and Formins, limb deformity genes in mice. As effectors for activated, GTP-bound Rho,...
متن کاملRICE MORPHOLOGY DETERMINANT encodes the type II formin FH5 and regulates rice morphogenesis.
Multicellular organisms contain a large number of formins; however, their physiological roles in plants remain poorly understood. Here, we reveal that formin homology 5 (FH5), a type II formin mutated in rice morphology determinant (rmd), plays a crucial role in determining rice (Oryza sativa) morphology. FH5/RMD encodes a formin-like protein consisting of an N-terminal phosphatase tensin (PTEN...
