SUB1B — Oryza sativa Indica Group

Summary

BGIOSGA038064 (SUB1B, OiSUB1B) in Indica rice encodes a transcription factor with an AP2/ERF DNA-binding domain, localised to the nucleus and annotated with DNA binding and transcription cis-regulatory region binding activities. The gene is associated with submergence tolerance, a phenotype observed for SUB1B in this species. It is linked to responses to submergence, underwater shoot and internode elongation, and the binding of SUB1A with SAB22. Annotated biological process associations include fermentation, starch metabolism, ethylene-mediated signalling, chlorophyll breakdown, stress and defence responses, and signal transduction. Related genes in other species link the family to seed germination.
