PAP1 — Brassica napus

Summary

BnPAP1 (DARMORV10_A07P33330.1) on chromosome A07 of oilseed rape encodes a MYB transcription factor with DNA-binding, transcription factor activity, protein dimerization, ubiquitin ligase, and protein kinase activities. It is associated with the regulation of flavonoid and proanthocyanidin anabolism, anthocyanin metabolism, pigmentation, petal development, seed growth, mucilage anabolism and extrusion from the seed coat, trichome spacing, epidermal cell fate specification, and responses to UV-A and sucrose signaling. The gene has been linked to traits including flower and seed coat color, flavonoid content, root epidermal cell length, leaf trichome density, seed longevity, cadmium and iron concentration, phosphorus uptake, lignin biosynthesis, and responses to light quality, UV, and viral disease. Studies of related genes in other species connect the family to anthocyanin pigmentation, trichome and root hair differentiation, light responsiveness, and salt stress tolerance.
