OsGSK2-OsBSK3 feedback loop controls rice BR signaling
Abstract Brassinosteroids (BRs) are essential plant hormones that regulate growth and development, including leaf angle regulation and grain size determination. Maintaining appropriate BR signaling requires precise coordination between pathway activation and attenuation. BR signaling is initiated by OsBRI1 activation, which triggers a phosphorylation cascade that ultimately inhibits OsGSK2…
