Highlights•Abaxial sclerenchyma cell number in rice lamina joints affects leaf erectness•Brassinosteroids (BRs) inhibit abaxial proliferation•CYC U4;1 is a U-type cyclin controlling proliferation•BR signaling regulates both CYC gene expression and protein activitySummaryLeaf erectness key determining plant architecture yield, particularly cereal crops. Brassinosteroids play unique role this trait monocots, but the underlying cellular molecular mechanisms remain big mysteries. Here we report...
Cryptochromes (CRYs) are blue light photoreceptors that mediate a variety of responses in plants and animals, including photomorphogenesis, flowering, circadian rhythms. The signaling mechanism by which Arabidopsis thaliana cryptochromes CRY1 CRY2 promote photomorphogenesis involves direct interactions with COP1, RING motif-containing E3 ubiquitin ligase, its enhancer SPA1. Brassinosteroid (BR) is key phytohormone involved the repression here, we show inhibition BR signaling. physically...
The phytohormone ABA is a key stress signal in plants. Although the identification of receptors led to significant progress understanding Arabidopsis signaling pathway, there are still many unsolved mysteries regarding monocots, such as rice. Here, we report that rice ortholog AtABI1 and AtABI2, named OsABI-LIKE2 (OsABIL2), plays negative role signaling. Overexpression OsABIL2 not only insensitivity, but also significantly altered plant developmental phenotypes, including stomatal density...
