TB1 — Zea mays

Summary

ZM00001EB312380 (TB1, also known as ZmREP1) on maize chromosome 7 encodes a TCP domain-containing transcription factor with sequence-specific DNA binding activity. This nuclear protein is associated with the regulation of shoot development, inflorescence development, shade avoidance, organogenesis, specification of symmetry, determination of dorsoventral asymmetry, and regulation of secondary shoot 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 shape, root number and length, crown root number, branch angle, spikelet fertility, seed size, grain weight, anthesis time, and salt tolerance. Additional associations include cell aggregation, spore formation, mating, vision, mitochondria localization, abscission, and starch metabolism. Related genes in other species link the family to tillering and inflorescence branching.
