TT8 — Camelina sativa

Summary

CsTT8 (CSA13G044750) on Camelina sativa chromosome 13 encodes a basic helix-loop-helix (bHLH) transcription factor with DNA-binding and protein-dimerization activity. The gene is associated with the regulation of flavonoid, anthocyanin, and proanthocyanidin anabolism, as well as phenylpropanoid metabolism and downregulation of sinapate ester anabolism. It has been linked to seed coat color and morphology, mucilage anabolism during seed coat development, trichome differentiation, and plant epidermal cell fate specification. Additional associations include responses to UV light, oxidative stress, cadmium, and temperature extremes, along with traits such as seed weight, germination rate, plant height, stem dry weight, root hair density and length, and relative growth rate. The protein localizes to both the nucleus and cytoplasm and is associated with sucrose-mediated signaling and regulation of secondary cell wall biogenesis.
