Abstract excerpt
Development of the cauliflower phenotype in Arabidopsis thaliana requires mutations at both the CAULIFLOWER and APETALA1 loci. BoAP1 is the Brassica oleracea orthologue to the Arabidopsis AP1 gene, and is present in two copies in Brassica genomes. The BoAP1-A gene appears to encode a full-length protein, but BoAP1-B alleles in B. oleracea contain insertions that lead to premature translation termination. The...
