AN3 — Oryza sativa Indica Group

Summary

BGIOSGA009861 (OiAN3, also known as OiGIF1) on chromosome 3 of Indica rice encodes an SS18 N-terminal domain-containing protein with multiple annotated molecular functions including fucosidase, beta-glucosidase, translation repressor, and ATP-dependent chromatin remodeler activities. This gene is associated with embryonic meristem initiation, floral whorl morphogenesis, organ boundary specification, seed development, and reproductive meristem phase change. It localizes to the nuclear lamina, SAGA complex, and SWI-SNF complex. OiAN3 is linked to numerous agronomic traits including panicle number, plant size, photoperiod sensitivity, and responses to abiotic stresses such as boron, copper, and aluminum. Related genes in other species are linked to organ size, leaf cell size, floral development, drought and salt stress responses, and immunity.
