TB1 — Zea mays

Summary

ZM00001EB099370, also known as TB1 and ZmREP1, encodes a sequence-specific DNA-binding transcription factor that localises to the nucleus. In maize, this gene is associated with the regulation of shoot development, meristem initiation, organogenesis, and the specification of symmetry, as well as shade avoidance, abscisic acid breakdown, starch metabolism, and spore formation. It has been linked to numerous agronomically important traits, including tiller number, tassel branch number, ear number, plant height, stem diameter, leaf number and angle, root number and length, grain weight, grain yield, seed size, heterosis, anthesis time, and cold tolerance. The gene is also connected to crown root number, branch angle, spikelet fertility, and stem elongation. Related genes in other species link the family to tillering and inflorescence branching.
