TCP7 — Brassica oleracea var. botrytis

Summary

BoTCP7, encoded by gene BOLND125_C09P007930.1 on cauliflower chromosome 9, is a TCP family transcription factor with DNA-binding transcription activator activity and protein homodimerization activity, localizing to the nucleus. This gene is associated with the regulation of circadian rhythm and the timing of the vegetative-to-reproductive phase transition, including upregulation of long-day photoperiodism and flowering. BoTCP7 has been linked to numerous developmental and morphological traits, including leaf size, petiole size, root width, anther morphology, pollen fertility restoration, and brassinosteroid sensitivity. Additional associations include sporocyte differentiation, cell cycle, and shoot apical meristem development. Studies of related TCP family members in other species connect this gene family to endoreplication, immune signaling, sporogenesis, and heat stress memory, though these functions are not yet established for BoTCP7 itself.
