AGL9 — Brassica oleracea var. botrytis

Summary

BoAGL9 (also known as BoSEP3 or AGL9) on cauliflower chromosome 5 encodes a protein with MADS-box and K-box domains, with annotated activities including DNA-binding transcription factor activity, transcription coactivator and corepressor activity, and histone H3K27me2/H3K27me3 demethylase activity. The gene is associated with biological processes such as negative regulation of seed maturation, fruit abscission, regulation of proanthocyanidin and mucilage pectin anabolism, gibberellin catabolism, abscisic acid breakdown, and downregulation of short-day photoperiodism, flowering. It is linked to floral and reproductive traits including floral organ length, carpel and sepal morphology, petal number, flower morphology, fruit ripening, silique fruit morphology, seed coat hardness and color, seed longevity, and plant male sterility. Additional associations include osmotic adjustment capacity, leaf shattering, aluminum response, and vegetative to reproductive phase transition. The protein localizes to the nucleus, cytoplasm, plastid, and plasmodesmata.
