Molecular Evaluation of the Effects of Homologs and Coordinating Regulators on the Flowering Responses to Vernalization in Cabbage ( var. ) Genotypes.

The flowering loci of cabbage must be understood to boost their productivity. In this study, to clarify the flowering mechanisms of cabbage, we examined the three flowering repressors , and , and the flowering regulators , , and of early (CAB1), middle (CAB3), and late (CAB5) flowering cabbage genotypes. Analysis of allele-specifically amplified genomic DNA and various sequence alignments demonstrated that maximal insertions and deletions influenced cabbage flowering behavior, notably in CAB3 and CAB5.
