Abstract: Forty-eight thousand coding DNA sequences of cabbage were used to analyze the relative frequency of synonymous codon(RFSC). Six high-frequency codons including TCT,CCT,AGA,GTT,GCT,and GAT were revealed by CodonW. When the frequency of codon usage of cabbage was compared to Escherichia coliArabidopsis thaliana,and Oryza sativa,we found that the codon preference was considerably different between cabbage and Escherichia coliOryza sativa,while the codon preference was identical between cabbage and Arabidopsis thalianaGossypium hirsutum. The codons of Bt cry1C gene sequence have been reconstructed according to the results. The foreigngene containing the optimal codons of cabbage is helpful to researches involving cabbage transformation.

Key words: cabbage, codon usage, high-frequency condon, condon preference
