FTM6 — Oryza sativa Japonica

Summary

OsFTM6 (also known as OsSPL3, OsSPL4, OsSPL7, and FTM6) on rice chromosome 4 encodes a protein containing an SBP domain, with annotated molecular functions including DNA-binding transcription activator activity, sequence-specific DNA binding, and protein kinase activity. The gene is associated with the regulation of vegetative phase change, inflorescence development, leaf senescence, and the transition from vegetative to reproductive phase. In rice, OsSPL7 has been linked to stress response, pathogen resistance, plant architecture, tiller number, height, and reactive oxygen species. The gene is also associated with agronomically important traits such as grain number, grain size, panicle length, tiller number, plant height, bacterial blight disease resistance, and low temperature stress response. Related genes in other species link the SBP family to thermotolerance, drought tolerance, and defense responses.
