摘要
Using the direct amplification of genomic DNA from two cultivars of leaf mustard (Brassica juncea), we obtained two homologs of the MADS-box gene FLOWERING LOCUS C(FLC), which regulates flowering time in arabidopsis. Nucleotide and deduced amino acid sequences of two cloned FLC fragments (from exon 2 to exon 7) were compared to the previously characterized FLC genes in arabidopsis and FLC homologs in other Brassicaceae species. The homolog AY266265 is an ortholog of the FLC3 gene from Brassica rapa (95% identity), whereas the function of the homolog AY268931 has not been established conclusively. The FLC gene and its homologs were used to compare the variability in the primary structures of exons and introns.
