AP2 — Brachypodium distachyon

Summary

BRADI_2G02100V3 (BdAP2) encodes a transcription factor of the AP2/ERF family, possessing DNA-binding and transcription cis-regulatory region binding activities, and is localized to the nucleus. In Brachypodium distachyon, this gene is associated with stomatal closure, ethylene-mediated signaling, responses to stress, heat, salinity, and thirst, as well as defense responses, cell division, and DNA-dependent transcription. It has also been linked to grain number and grains per spike. Studies of related genes in other species connect the AP2/ERF family to a wide range of agronomic traits, including seed length, width, and weight, panicle and spikelet characteristics, cob diameter, stem thickness, leaf angle, root volume, biomass yield, and floral organ identity.
