TCP7 — Brassica oleracea var. botrytis

Summary

BoTCP7, located on chromosome 7 of cauliflower (Brassica oleracea var. botrytis), encodes 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, the timing of the vegetative-to-reproductive phase transition, and sporocyte differentiation. It has been linked to numerous traits including flowering time, leaf size and morphology, petiole size, root width, anther morphology, pollen fertility restoration, brassinosteroid sensitivity, and plant morphology. Associations also extend to leaf and hypocotyl development, cell size, root size, male fertility, microsporocyte generation, ovule development, and immune responses such as systemic acquired resistance and PAMP-triggered immunity. Studies of related genes in other species connect the TCP family to endoreplication, immune signaling, sporogenesis, and heat stress memory.
