摘 要: 采用高频密码子分析法,对甜橙C itrus sinensis、温州蜜柑C.unshiu、葡萄柚C.paradisi和柠檬C.lim on等4种柑橘的蛋白质编码基因序列(codon DNA sequence,CDS)进行了分析,计算出了柑橘同义密码子相对使用频率(rela-tive frequency of synonymous codon,RFSC),确定出了4种柑橘的高频率密码子,发现不同种类柑橘偏爱密码子稍有差别. Codon DNA sequence (CDS) of four different citrus species, including sweet orange (Citrus sinensis), satsuma mandarin (C. unshiu), grapefruit (C. paradisi) and lemon (C. limon) were used to analyze the relative frequency of synonymous codon (RFSC) , and high-frequency codons were selected by high-frequency codon analysis. The results indicated that the codon preference was little different in four citrus species.
