PFT1 — Brassica oleracea var. botrytis

Summary

BoPFT1 (BOLND125_C02P070950.1) on cauliflower chromosome 2 encodes a protein with transcription coactivator activity, sequence-specific DNA binding, and ubiquitin-like protein ligase activity, and belongs to the mediator complex. It is associated with the regulation of defense responses to insects, jasmonic acid/ethylene-dependent systemic resistance, positive regulation of photomorphogenesis, and inhibition of brassinosteroid-mediated signaling. The gene is linked to numerous agronomic traits including photoperiod-sensitive flowering time, inflorescence bract development, seed protein and oleic acid content, iron and cadmium concentration, nitrogen recycling, phosphorus uptake, lignin biosynthesis, shoot branching, lateral root number, and responses to submergence, UV-B light, aluminum, and aphids. It also shows associations with hypoxia tolerance, photosynthetic efficiency, redox homeostasis, and seed embryo development. Related genes in other species are linked to flowering time regulation, abiotic stress tolerance, and resistance to fungal pathogens and viruses.
