FRG1 — Brachypodium distachyon

Summary

BdFRG1 (BRADI_3G15380V3) on chromosome 3 of Brachypodium distachyon encodes a SNF2/RAD54-family helicase with ATP-dependent chromatin remodeler activity, DNA translocase activity, nucleosome binding, and histone binding. It is associated with abscisic acid signaling, stomatal closure, regulation of endosperm development, chromatin silencing, DNA repair and recombination, and activation of cellular response to heat stress. The gene has been linked to salinity tolerance, reproductive period, delayed flowering, reduced root growth, and reduced DNA methylation. Its product localizes to the nucleus, chromosome, chromatin, and nucleolus. Studies of related genes in other species connect the family to immune response, disease, blast, and immunity, while sequence similarity links the family to grain weight, grain yield, plant height, spike length, chlorophyll content, and drought sensitivity.
