LAS — Oryza sativa Japonica

Summary

OS06G0610350, also known as MOC1 or LAS, encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. In rice, MOC1 is associated with tiller bud outgrowth, tiller number, plant height, grain yield, spikelet number, root number and length, stem elongation, days to heading, seed shattering, and meristem identity. The gene is associated with meristem development and initiation, organogenesis, axillary shoot meristem initiation, cell division, cell cycle, anaphase, abscission, seed germination, GA and ABA signaling, nitrate import, and bundle sheath cell fate specification. The protein localizes to both the cytoplasm and nucleus. Studies of related GRAS family members in other species connect the family to shoot branching, axillary meristem formation, panicle number, grain weight, and floral organ number.
