| 摘 要： | 芸薹属作物是十字花科中重要的蔬菜和油用作物,经济价值和食用价值比较高。本研究通过生物信息学手段,从3个芸薹属物种EST序列中获得了大量的SNP和Indel资源,对SNP与EST的数量及拼接结果之间的关系、SNP碱基置换的偏好性、Indel碱基数量与发生频率之间的关系进行了分析。分析结果对深入研究芸薹属基因组特点具有一定的参考价值,为进一步通过试验验证预测的SNP位点、开发该作物高通量SNP分子标记奠定了基础。

| Abstract: | As one of vegetable and oil crops in Cruciferae,genus Brassica has highly economic and edible values.In this research a number of SNPs and indels were obtained from EST sequences of three Brassica species by bioinformatic tools.The relationship between spelling results and the number of SNP and EST,preference of nucleotide replacement,and the relationship between amount and frequency of nucleotides were further analyzed.The results will be useful to gain insight into the characteristics of Brassica genome.T... |
