FC1 (TRAESCS4D02G040100) — triticum aestivum

Summary

TRAESCS4D02G040100 (symbol FC1, also known as TB1) on bread wheat chromosome 4D encodes a TCP transcription factor containing a CYC/TB1_R domain, with sequence-specific DNA binding activity. This gene is associated with the regulation of shoot development, secondary shoot formation, flower development, and specification of symmetry. It has been linked to tiller number, ear number, plant height, stem internode elongation, leaf number, and inflorescence branching. The gene is associated with strigolactone-mediated axillary bud dormancy and suppression of tillering, as well as shoot gravitropism. Related genes in other species link the family to tillering, branching, auxin and strigolactone responses, dwarfism, lodging, grain yield, and panicle development. The encoded protein localises to the nucleus.
