摘　　要：为了解雌雄异株植物间MADS-box基因家族的密码子使用偏好性特点,以拟南芥为参照,利用Gen-Bank Feature Extractor,Codonw和CUSP等软件对已发表的雌雄异株植物MADS-box基因序列的密码子偏好性进行分析,发现拟南芥及雌雄异株植物中均偏好使用密码子第3位点为U和A的密码子.再运用SPSS11.5对拟南芥和雌雄异株植物的MADS-box基因密码子偏好性进行聚类分析,发现雌雄异株植物与拟南芥在MADS-box基因的密码子选择偏好方面的差异不显著.从而得出雌雄异株植物对MADS-box基因密码子偏好性不具有显著影响.In order to know the codon bias characteristics of different genes from dioecious plants, the study has analyzed by some softwares （GenBank Feature Extractor, codonw and cusp）. The results show that MADS-box genes in Arabidopsis and dioecious plants prefer A-ending and U-ending codons. However, through the hierarchical cluster analyse method of SPSSll. 5, it has been found that there are not obvious differences in the codon bias of MADS-box genes between Arabidopsis and dioecious plants, thus it is proved that it a negative significant correlation between dioecious plants and the codon bias of MADS-box genes.
