PAP1 — Brassica napus

Summary

BnPAP1 (also known as PAP1, MYB90, and BnPAP1-D) on chromosome C02 of oilseed rape encodes a Myb-domain transcription factor with DNA-binding, transcription factor, protein dimerization, ubiquitin ligase, and protein kinase activities. It is associated with the regulation of flavonoid, proanthocyanidin, and anthocyanin biosynthesis, as well as pigmentation, petal development, seed growth, mucilage production, trichome spacing, and responses to UV-A light and sucrose signaling. The gene is 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, and responses to light quality, UV, and viral disease. Related genes in other species are associated with anthocyanin pigmentation, insect resistance, iron accumulation, and salt stress tolerance.
