AN3 — Oryza sativa Japonica

Summary

OsAN3 (also known as OsGIF1, OsGIF3) on rice chromosome 3 encodes a protein containing an SS18_N domain and is annotated with diverse molecular functions including protein binding, bridging, and transcription corepressor activity. The gene is associated with numerous biological processes such as embryonic meristem initiation, floral whorl morphogenesis, formation of plant organ boundaries, and maintenance of seed dormancy. It is linked to a wide range of agronomically important traits including fruit yield, plant organ growth and development, plant cell size, spikelet fertility, whole plant size, rolled leaf, photoperiod sensitivity, and responses to copper, boron, aluminum, and aphids. The encoded protein localizes to the nuclear lamina, SAGA complex, and SWI-SNF complex. Studies of related genes in other species connect the family to organ size, leaf cell size, floral development, and drought response.
