FC1 — Zea mays

Summary

ZM00001EB054440 (ZmFC1, also known as TB1) on maize chromosome 1 encodes a TCP family transcription factor containing a CYC/TB1_R domain. The protein localises to the nucleus and exhibits sequence-specific DNA binding activity. ZmFC1 is associated with the regulation of shoot development, secondary shoot formation, inflorescence development, leaf development, shade avoidance, and specification of symmetry. It has been linked to agronomically important traits including tiller number, plant height, ear number, tassel branch number, grain weight, seed size, stem diameter, root number, crown root number, lateral root length, leaf number and shape, spikelet fertility, anthesis time, and salt tolerance. The gene is also connected to strigolactone-mediated axillary bud dormancy, shoot gravitropism, and starch metabolism. Related genes in other species link the family to tillering, panicle number, grain yield, and lodging resistance.
