PAP1 — Brassica oleracea

Summary

BoPAP1 (BOLC102_C06P043920.1_BOLC102_V1) on cabbage chromosome 6 encodes a protein with a Myb_TF_plants domain, a Myb domain, a SANT/Myb domain, and a Homeodomain-like superfamily domain. It is associated with DNA binding, DNA-binding transcription factor activity (RNA Polymerase II-specific), protein dimerization activity, ubiquitin ligase activity, ubiquitin-protein transferase activity, protein kinase activity, transcription cis-regulatory region binding, identical protein binding, ATP binding, and protein binding. The gene is associated with the regulation of flavonoid, proanthocyanidin, and anthocyanin anabolism, pigmentation, seed growth, mucilage anabolism and extrusion, trichome spacing, epidermal cell fate specification, and sucrose-mediated signaling. It is linked to numerous traits including flavonoid content, seed coat color, leaf trichome density, root epidermal cell length, light quality responses, cadmium concentration, iron concentration, seed longevity, heterosis, lignin biosynthesis, phosphorus uptake, and viral disease response. Studies of related genes in other species link the family to anthocyanin pigmentation, trichome and root hair differentiation, light responsiveness, salt stress tolerance, and insect resistance.
