TT8 — Asparagus officinalis
Summary
AoTT8 (TT8, BHLH42) on asparagus chromosome 3 encodes a DNA-binding transcription factor with protein dimerization activity. It is associated with the regulation of anthocyanin, proanthocyanidin, and flavonoid biosynthesis, as well as phenylpropanoid metabolism and seed coat development. The gene is linked to traits including anthocyanin and flavonoid content, seed weight, plant height, root length, stem dry weight, photosynthetic rate, and responses to UV light, high and low temperature, oxidative stress, and biotic stress. It is also connected to trichome differentiation, cell fate commitment, and secondary cell wall biogenesis. Studies of related genes in other species link the family to proanthocyanidin accumulation, seed coat pigmentation, trichome formation, and UV-B tolerance.
