摘要: 【目的】构建白菜(Brasscia campestris ssp. chinensis)分子转录图谱。【方法】以矮脚黄白菜自交系(97-3-2)和白蔓菁芜菁自交系(001-24),以及以两者为亲本杂交建立的F6重组自交系群体为材料,在莲座期取嫩叶提取RNA并反转录成cDNA,采用cDNA-AFLP技术,利用256对cDNA-AFLP引物对亲本97-3-2、001-24之间的多态性进行检测,筛选出56对多态性引物用于F6群体分析,通过对cDNA-AFLPs分子标记的遗传分析构建图谱。【结果】构建了一个包括164个 cDNA-AFLPs 分子标记的分子转录图谱。该图谱由13个连锁群组成,图谱总长度为1 401.2 cM,标记间平均图距9.7 cM。【结论】这是第一份利用cDNA-AFLP标记构建的白菜分子转录图谱。

Abstract: 【Objective】Developing construction of cDNA-AFLPs molecular transcriptome map of Chinese cabbage-pak-choi (Brassica campestris L. ssp. chinensis Makino), which can establish the molecular basis of molecular breeding and heterosis for Chinese cabbage.【Method】With the inbred line ‘Aijiaohuang 97-3-2’, the inbred line ‘Baimanjing 001-24’ of turnip [B. campestris ssp. rapifera (Matzg.) Sinsk ] and F6 recombinant inbred(RI) population as experimental materials, Using 56 couples cDNA-AFLP primers out of 256, the segregation and distribution of cDNA-AFLPs in parents and F6 plants were analysized. 【Result】A total of 138 cDNA-AFLPs marker loci were mapped to 12 linkage groups, covering 1309.5 cM with an average distance of 9.2 cM. 【Conclusion】It was the first transcriptome map of Chinese cabbage by using cDNA-AFLP.
