AP1 (BOLC102_C06P047480.1_BOLC102_V1) — Brassica oleracea

Summary

BoAP1 (AP1, AGL7) on cabbage chromosome 6 encodes a MADS-box transcription factor with RNA polymerase II-specific DNA-binding, transcription coactivator and corepressor activities, and is also annotated with mRNA regulatory element binding translation repressor activity, histone H3K27me2/H3K27me3 demethylase activity, and chromatin binding. It is associated with floral whorl development, abscisic acid breakdown, regulation of proanthocyanidin anabolism, release of seed from dormancy, and differential growth. The gene is linked to numerous flower, fruit, seed, and leaf morphology traits, including floral organ size, petal number, fruit shape, seed color, leaf margin serration, and fruit shattering. It is also connected to floral meristem identity, fruit development, inflorescence determinacy, and pod shatter. Related genes in other species are linked to seed yield, petal and stamen identity, leaf longevity, and temperature-responsive flowering.
