WebFurthermore, we found that OsMYB7 affects endogenous auxin levels in lamina joints, and the adaxial cells of lamina joints in OsMYB7-overexpressing lines and osmyb7 knockout mutants exhibited enhanced and reduced elongation, respectively, compared to the wild type. These results suggest that OsMYB7 promotes leaf inclination partially through ...

WebMay 12, 2024 · Cell division is a predominant process when the lamina joint initially develops, and along with cell division, cell expansion starts and lasts longer at the adaxial side, leading to asymmetric growth and, hence, leaf inclination (cell wall thickening provides mechanical support). WebMar 9, 2024 · The lamina joint bending angles of the T 1 progenies of the mutant uORF were smaller than those of WT plants (Fig. 2f,g), whereas the levels of OsDLT transcripts were similar (Fig. 2h).
WebBRs regulate the asymmetric elongation of adaxial cells of the lamina joint to control rice leaf angle (Tong and Chu, 2024). The disruption of the components in BR biosynthesis WebThe leaf angle in rice is determined by the lamina joint that connects the leaf blade and leaf sheath. Compared with the leaf tissue, mesophyll cells were replaced by parenchyma cells, and more sclerenchyma cells were gathered around the vascular bundles on the adaxial and abaxial sides.
WebIn this review, we discuss cell morphology in different lamina joint tissues and describe the underlying genetic network that governs this morphology and thus regulates leaf direction. Furthermore, we focus on the mechanism by how environmental factors influence rice leaf angle. Our review provides a theoretical framework for the future genetic ... WebMar 27, 2024 · The CYC U4;1 encoding U-type cyclin abundantly expresses in lamina joints. The BR regulated expression of CYC U4;1 has been proposed to be essential step in regulating lamina joints development through controlling the abaxial sclerenchyma cell proliferation in rice (Sun et al. 2015 ).
WebOct 3, 2024 · Leaf angle depends on cell division, expansion, and cell wall composition in the lamina joint . Multiple external and internal factors, including nutrients, carbon dioxide, temperature, phytohormones, and plant genotypes, are involved in modulating leaf angle [10,17,18]. Among these regulators, phytohormone BR is the most important leaf-angle ...
WebThe cell elongation-promoting activities of brassinolide (BR) and indoleacetic acid (IAA) in the lamina-inclination test using etiolated rice seedlings were compared at a low temperature. IAA promoted the lamina joint-cell elongation at 30°G, but the effect was markedly lowered with decreasing temperature and reached null at 15°C. bosch cordless track saw reviewWebJun 1, 2024 · The division and elongation of the lamina joint cells on the adaxial or abaxial sides regulate LIA of rice (e.g., Zhang et al., 2009; Zhao et al., 2010, 2013; Zhang et al., 2015; San et al., 2024). Vascular bundle formation and cell wall composition also influence LIA through their effects on mechanical strength of the lamina joint (Ning et al ... having faith in god versesWebApr 14, 2024 · However, auxin induces cell elongation when present at low levels (Chen et al., 2001), and reduced auxin contents in lamina joints at the S5 developmental stage give rise to excessive cell elongation at the adaxial side of lamina joints, promoting lamina … having faith in god\u0027s wordWebThe degree of leaf bending depends on the morphology of the lamina joint, which connects the leaf and the sheath.
