AS1 — Brassica oleracea var. botrytis

Summary

BoAS1 (AS1, MYB91) on cauliflower chromosome 3 encodes a protein with Myb domain, SANT/Myb, Homeodomain-like superfamily, and Leaf_Dev_Regulator domains, and is annotated with transcription regulator activity, DNA-binding transcription activator activity, sequence-specific DNA binding, and chromatin binding. It is associated with leaf formation, adaxial/abaxial axis specification, proximodistal axis specification, organ boundary specification, and leaf margin serration. The gene is linked to yield, leaf number, leaf flexibility, leaf water potential, photoperiod-sensitive flowering time, days to flowering, shoot growth angle, auxin content, brassinosteroid content, jasmonic acid sensitivity, UV-B light sensitivity, nitrate transport, raffinose content and breakdown, and mucilage pectin metabolism. It localises to the nucleolus, plastid, chloroplast envelope, plasmodesma, and chromatin silencing complex. Related genes in other species are linked to leaf polarity, floral organ development, and plant fertility.
