In much of the tropics and subtropics, rice (Oryza sativa L.) is grown under long days (LDs). Therefore, LD must play a major role in inducing flowering signal rice. However, little known on LD-dependent species. We previously reported that OsMADS50, which highly homologous to Arabidopsis SOC1, functions as positive regulator for flowering. its detailed photoperiodic mechanism was not yet elucidated. Here, we report functional analysis OsMADS50 closely related gene OsMADS56. Knock-out caused...
Plants recognize environmental factors to determine flowering time. CONSTANS (CO) plays a central role in the photoperiod pathway of Arabidopsis, and CO protein stability is modulated by photoreceptors. In rice, Hd1, an ortholog CO, acts as promoter, phytochromes repress Hd1 expression. Here, we investigated functioning OsCOL4, member CONSTANS-like (COL) family rice. OsCOL4 null mutants flowered early under short or long days. contrast, activation-tagging (OsCOL4-D) late either environment....
Summary The plant U‐box (PUB) protein functions as an E3 ligase to poly‐ubiquitinate a target for its degradation or post‐translational modification. Here, we report functional roles OsPUB15 , which encodes cytosolic in the class‐II PUB family. Self‐ubiquitination assays showed that bacterially expressed MBP‐OsPUB15 has ubiquitin activity. A T‐DNA insertional mutation caused severe growth retardation and seedling‐lethal phenotype. Mutant seeds did not produce primary roots, their shoot...
Shoot branching is an essential agronomic trait that impacts on plant architecture and yield. determined by two independent steps: axillary meristem formation bud outgrowth. Although several genes regulatory mechanism have been studied with respect to shoot branching, the roles of chromatin-remodeling factors in developmental process not reported rice. We previously identified a factor OsVIL2 controls trimethylation histone H3 lysine 27 (H3K27me3) at target genes. In this study, we report...
