PAP1 — Brassica oleracea

Summary

BoPAP1 (BOLC102_C03P056600.1) on cabbage chromosome 3 encodes a MYB-family transcription factor with DNA-binding, transcription factor, protein dimerization, ubiquitin ligase, and protein kinase activities. It is associated with the regulation of anthocyanin, flavonoid, and proanthocyanidin biosynthesis, as well as pigmentation, seed growth, mucilage production, trichome spacing, and epidermal cell fate specification. The gene is linked to traits including flavonoid content, seed coat color, leaf trichome density, root epidermal cell length, light sensitivity, cadmium and iron concentration, seed longevity, lignin biosynthesis, phosphorus uptake, and viral disease response. Studies of related genes in other species connect the family to anthocyanin pigmentation, trichome differentiation, root hair development, salt stress tolerance, and circadian rhythm.
