AP2 — Oryza sativa Indica Group

Summary

BGIOSGA002708 (OiAP2, also known as AP2 or PTI6) on chromosome 1 of Indica rice encodes a transcription factor of the AP2/ERF ERF subfamily, possessing DNA-binding and transcription cis-regulatory region binding activity, and localises to the nucleus. The gene is associated with a wide range of biological processes, including ethylene-mediated signalling, ABA signalling, auxin transport, defence response, endocytosis, and metabolism of S-adenosylmethionine, methionine, carbohydrates, fatty acids, and nitric oxide storage. It is linked to numerous agronomic traits, such as grain yield, grain weight, grain length and width, spikelet fertility and sterility, panicle length, tiller number, plant height, and cold tolerance. Related genes in other species are linked to additional traits including seed length, spike density, anther extrusion, and biomass yield.
