MAS2 — Brassica oleracea var. botrytis

Summary

BoMAS2 (MAS2) on cauliflower chromosome 9 encodes a protein with NKAP and NKAP_C domains. The gene is associated with DNA endonuclease activity producing 3′-phosphomonoesters, 5′ flap endonuclease activity, RNA endonuclease activity, RNA helicase activity, and binding of nucleic acids, chromatin, actin, siRNA, and miRNA. It is linked to miRNA biogenesis, post-transcriptional gene silencing, rRNA maturation, ribosomal subunit assembly, auxin metabolism, leaf patterning, adventitious root development, and positive regulation of mitotic entry. It localizes to the nucleolus, plastid, cell wall, microprocessor complex, and spliceosomal complex. BoMAS2 is associated with traits including seed yield, flowering time, leaf morphology, inflorescence architecture, submergence tolerance, viral and aphid responses, high and low temperature stress responses, and embryo viability. Related genes in other species are linked to abscisic acid sensitivity, viral resistance, leaf senescence, and susceptibility to Botrytis cinerea and Sclerotinia sclerotiorum.
