TT8 — Phaseolus vulgaris

Summary

PvTT8 (PHAVU_001G150300) on chromosome 1 of French bean encodes a protein with a MYC/MYB_N domain, a bHLH-TF_ACT-like_plant domain, a bHLH domain, and an HLH_DNA-bd_sf domain, and is annotated with DNA binding transcription factor activity, sequence-specific DNA binding, transcription cis-regulatory region binding, DNA binding, protein dimerization activity, and protein binding. The gene is associated with regulation of flavonoid, proanthocyanidin, and anthocyanin anabolism, pigmentation, plant epidermal cell fate specification, trichome differentiation, and other biological processes. It is linked to seed color, seed weight, germination rate, stem dry weight, root hair length, flowering time, UV-B light sensitivity, high temperature stress response, low temperature stress response, oxidative stress response, biotic plant stress trait, cadmium concentration, oleic acid content, and lignin biosynthesis trait. Studies of related genes in other species link the family to proanthocyanidin accumulation, anthocyanin pigmentation, seed coat pigmentation, trichome formation, root hair development, and UV-B tolerance.
