ZIM — Brachypodium distachyon
Summary
BdZIM (BRADI_1G33980V3) on Brachypodium distachyon chromosome 1 encodes a nuclear protein with TIFY, Znf_GATA, and CCT domains that exhibits DNA-binding transcription factor activity, sequence-specific DNA binding, telomeric repeat binding, and RNA binding. The gene is associated with jasmonic acid signaling, circadian rhythm, meristem maintenance, root meristem growth, stem cell population maintenance, anther dehiscence, and positive regulation of telomere maintenance via telomerase. It has been linked to flowering time, seed viability, photoprotection, photosystem II quantum efficiency, telomere length maintenance, genome stability, and defense response. Studies of related genes in other species connect the family to telomere length regulation, plant viability, petiole and hypocotyl elongation, and flower and inflorescence development, while sequence similarity links extend associations to grain weight, plant height, drought tolerance, heat tolerance, seed dormancy, and arsenic concentration.
