[Objective]Analysis of FLC sequence that Vernalization-related genes in Arabidopsis.［Method］Advance through natural populations of Arabidopsis QTL analysis of vernalization response was found on chromosome 5 of Arabidopsis thaliana have a flowering-related QTL, this test is to use sequence analysis to determine whether it is with the FLC gene homology［Result］Arabidopsis thaliana, Italy and Sweden in the 27th, No. 461, p. 501, p. 638, p. 738, No. 884 different base. While these bases are different, but the codon encoding the first nine amino acids out of the first 167 amino acids, the first 246 amino acids, due to codon degeneracy, encode proteins that are the same. [Conclusion] Arabidopsis has a rich genetic diversity, the FLC gene is highly conserved sequence length, base variable sites rich degenerate codons encoding the same amino acids they are not affect the growth of Arabidopsis thaliana. This indicates that the Arabidopsis genome sequence will be the environment.
