SH4 — Oryza sativa Japonica

Summary

OS04G0670900 (SH4) on rice chromosome 4 encodes a Myb/SANT domain-containing DNA-binding transcription factor. The gene is associated with domestication, shattering, grain, growth, and development. SH4 is linked to seed abscission, hull color, grain shattering, seed shattering, pericarp color, yield trait, grain length, tiller number, seed size, photosynthetic rate, seed dormancy, grain size, plant height, grain yield, seed, spikelet, and yield. It is associated with chlorophyll a breakdown, lignin anabolism, pigmentation, signal transduction, and regulation of transcription. Related genes in other species link the family to grain color, anthesis time, root morphology, and drought tolerance.
