Summary

BoAP1 (AP1, AGL7) on cauliflower chromosome 6 encodes a MADS-box transcription factor with RNA polymerase II-specific DNA-binding activity, transcriptional co-regulator functions, and chromatin-related activities including histone binding and nucleosome array spacer activity. It is associated with floral whorl development, bract morphogenesis, floral meristem identity, and fruit development, as well as the regulation of proanthocyanidin anabolism, abscisic acid breakdown, and release of seed from dormancy. The gene has been linked to numerous agronomic traits including fruit yield, inflorescence size, flower morphology, floral organ number and size, petal number, sepal and carpel morphology, seed color, stem diameter, secondary shoot axis branch number, leaf margin serrated, and responses to boron and potassium. Studies of related genes in other species connect the family to petal and stamen identity, seed yield, leaf longevity, and temperature-responsive flowering.
