PAP1 — Brassica oleracea

Summary

BoPAP1 (BOLC102_C02P026460.1) on cabbage chromosome 2 encodes a protein with a Myb_TF_plants domain, a Myb domain, a SANT/Myb domain, and a Homeodomain-like superfamily domain, and is associated with DNA-binding transcription factor activity, protein dimerization activity, ubiquitin ligase activity, ubiquitin-protein transferase activity, protein kinase activity, and other molecular functions. It localizes to the nucleus, root hairs, nuclear ubiquitin ligase complex, nuclear body, and Cul4-RING E3 ubiquitin ligase complex. This gene is associated with the regulation of flavonoid, proanthocyanidin, anthocyanin, and mucilage biosynthesis, as well as pigmentation, seed growth, trichome spacing, epidermal cell fate specification, sucrose-mediated signaling, and circadian rhythm. Traits linked to this gene include flavonoid content, seed coat color, leaf trichome density, root epidermal cell length, light sensitivity (far-red, blue, UV, red), cadmium concentration, iron concentration, phosphorus uptake, seed longevity, lignin biosynthesis, starch grain synthesis, brassinosteroid content, viral disease response, and photoperiod-sensitive flowering time. Related genes in other species are linked to anthocyanin pigmentation, trichome differentiation, root hair differentiation, salt stress tolerance, and iron accumulation.
