AGL9 — Brassica oleracea

Summary

BoAGL9 (also known as AGL9 or SEP3) on cabbage chromosome 5 encodes a protein with MADS-box and K-box domains, possessing transcription regulator activity, DNA-binding transcription factor activity, and histone H3K27me2/H3K27me3 demethylase activity. The gene is associated with floral organ length, petal number, carpel and sepal morphology, flower morphology, fruit ripening, silique morphology, seed coat hardness and color, seed longevity, and plant male sterility. It is linked to negative regulation of seed maturation, fruit abscission, regulation of proanthocyanidin anabolism, abscisic acid breakdown, gibberellin catabolism, and downregulation of short-day photoperiodism. Localization evidence connects the product to the nucleus, cytoplasm, plasmodesmata, and plastid. Studies of related genes in other species link the family to floral organ identity, floral meristem determination, and seed oil accumulation.
