TT8 — Brassica napus

Summary

BnTT8 (TT8, BnBHLH42) on chromosome A09 encodes a protein with a basic helix-loop-helix (bHLH) domain and MYC/MYB_N domain, and has DNA binding, sequence-specific DNA binding, transcription cis-regulatory region binding, protein dimerization activity, and DNA binding transcription factor activity. In oilseed rape, it is associated with anthocyanin breakdown, pigment metabolism, downregulation of sinapate ester anabolism, cell cycle transition, pigment accumulation, regulation of flavonoid anabolism, regulation of proanthocyanidin anabolism, sucrose-mediated signaling, proanthocyanidin anabolism, response to dexamethasone, plant epidermal cell fate specification, cell development, removal of O2-, cell fate commitment, regulation of protein localization, mucilage anabolism during seed coat development, mucilage anabolism, and pigmentation. The gene is linked to seed color, seed coat color, seed coat morphology trait, seed weight, seed size, leaf color, plant height, root hair density, root hair length, trichome morphology trait, UV-B light sensitivity, UV light sensitivity, high temperature stress response, low temperature stress response, cadmium concentration, biotic plant stress trait, and other traits. It is also connected to stem dry weight, root epidermal cell length, flavonoid content, relative growth rate, lignin biosynthesis trait, oleic acid content, protein content, phototropism response trait, insect damage response trait, germination rate,
