Results indicated that tran-scription factor WRKY35 harbors a WRKYGQK core domain and a Cys2His2 or Cys2His/Cys zinc finger in the 5’ end without transmembrane domain. After PCR amplification and restriction digestion, WRKY35 gene fragment was ligated to prokaryotic expression vector PET28. This study provided basis for expression anal-ysis of WRKY35 protein and subsequent functional identification of WRKY35 gene.展开更多

[Method] Nine main commercial rapeseed cultivars in Guizhou were detected by 40 pairs of SSR primers used in the national regional trial of B. napus, and then clus-tering analysis was carried out. [Result] A total of 191 bands were amplified, and 143 （accounting for 75%） of them showed polymorphism among the nine rapeseed cultivars. By cluster analysis, the nine cultivars were divided into two groups. Group A included seven varieties, and group B consisted of two cultivars from Guizhou In-stitute of Oil Crops. The cultivars in group A were further divided into sub-groups A1 and A2 at the similarity coefficient of 0.643 4. Sub-group A1 included three culti-vars from Guizhou Rapeseed Institute, and sub-group A2 included the other four cultivars from Guizhou Institute of Oil Crops. [Conclusion] The cultivars bred by the same institute had similar genetic background. The cultivars from Guizhou Institute of Oil Crops showed wider genetic basis. However, the genetic similarity coefficient between Qianyou 17 and Qianyou 29 was up to 0.87, suggesting that they shared closer genetic basis.展开更多
