Transgenic Rape with hrf2 Gene Encoding HarpinXooc Resistant to Sclerotinia sclerotinorium
摘要
Abstract
The objective of this study was to increase the resistance of rape using the method of transformation. The gene hrf2 derived from Xathomonas oryzae pv. oryzicola encoding harpinXooc protein was constructed into transgenic vector pCAMBIA1301. The cotyledonal petiole segments from rapeseed variety Yangyou 4 were infected by Agrobacterium tumefaciens strain LBA4404/pCAMBIA1301-hrf2. Hygromycin-resistant green shoots were obtained. Successful integration of the foreign gene into the genome of the rapeseed variety Yangyou 4 was confirmed by PCR, RT-PCR, and β-glucuronidase analyses. Disease bioassays of transgenic plants revealed an improved resistance of transgenic plants to Rape sclerotiniose. In brief, the hrf2 gene can be transferred into rape using the method of Agrobacterium-medmted transformation, which increased the resistance to Sclerotinia sclerotinorium in the transgenic plant.关键词
