Crop yield potential is constrained by the inherent trade-offs among traits such as between grain size and number. Brassinosteroids (BRs) promote size, yet their role in regulating number unclear. By deciphering clustered-spikelet rice germplasm, we show that activation of BR catabolic gene BRASSINOSTEROID-DEFICIENT DWARF3 ( BRD3 ) markedly increases We establish a molecular pathway which signaling inhibitor GSK3/SHAGGY-LIKE KINASE2 phosphorylates stabilizes OsMADS1 transcriptional factor,...
Abstract Brassinosteroid (BR) phytohormones play crucial roles in regulating internode elongation rice (Oryza sativa). However, the underlying mechanism remains largely unclear. The dwarf and low-tillering (dlt) mutant is a mild BR-signaling-defective mutant. Here, we identify two dlt enhancers that show more severe shortening of lower internodes compared to uppermost (IN1). Both mutants carry alleles ORYZA SATIVA HOMEOBOX 15 (OSH15), founding gene for dwarf6-type mutants, which have...
Brassinosteroids (BRs) regulate various agronomic traits such as plant height, leaf angle, and grain size in rice (Oryza sativa L.); thus, BR signaling components are promising targets for molecular rational design. However, genetic materials BR-signaling genes or family members remain limited rice. Here, by genome editing using clustered regularly interspaced short palindromic repeats (CRSPR)/Cas9 tools, we generated a panel of single, double, triple, quadruple mutants within three gene...
The complex roles of the steroid hormone brassinosteroids (BRs) in many different yield- and stress-related traits make it difficult to utilize hormones for crop improvement. Here, we show that SERK2 as a BR signaling component is potentially useful candidate manipulation rice. We generated multiple mutant alleles by CRISPR/Cas9 editing knockout results compact structure accompanied with increased grain size. localized on plasma membrane can interact OsBRI1, receptor, suggesting its...
Japonica/geng and indica/xian are two major rice (Oryza sativa) subspecies with multiple divergent traits, but how these traits related interact within each remains elusive. Brassinosteroids (BRs) a class of steroid phytohormones that modulate many important agronomic in rice. Here, using different physiological assays, we revealed japonica exhibits an overall lower BR sensitivity than indica. Extensive screening signaling genes led to the identification set distributed throughout primary...
The rapid elongation of rice (Oryza sativa) coleoptile is pivotal for the plant plumule to evade hypoxia stress induced by submergence, a condition often arising from overirrigation, ponding, rainstorms, or flooding. While brassinosteroids (BRs) are recognized their diverse roles in growth and development, influence on under hypoxic conditions remains largely unexplored. In this study, we demonstrate significant requirement BRs deep water. During Glycogen Synthase Kinase3-Like Kinase2...
