| 英文摘要 | Transgene flow from engineeredBrassica napusto wild weed relatives could potentially have an environmental effect. To evaluate the introgression of transgenicB. napusinto wildBrassica juncea, the hybrid F(1)and backcross progenies derived fromB. juncea(genome constitution AABB) and transgenicB. napus(AACC) crosses were investigated. C-genome-specific simple sequence repeat (SSR) markers corresponding to linkage groups N11-N19 in B. napuswere screened and used to estimate the marker frequency in hybrid F(1)and backcross progenies. C-genome-specific markers could be stably detected in hybrid F-1 and backcross BC1 plants, but were only rarely found in the BC2-BC5 generations. For example, a specific SSR marker for linkage group N12 segregated in BC2 generation but were completely lost in BC3-BC5, while a specific SSR marker of linkage group N15 segregated in BC1, BC2 and BC3 generations and was absent in more advanced backcrossed generations (BC4 and BC5). The results indicate that a certain gene regions inBrassica napusplants are transmitted at a relatively lower frequency to wild relatives, and more rapidly disappeared in subsequent backcross generations. We propose that a foreign gene or transgene that is integrated in the C-chromosome ofBrassica napuscould reduce the risk of introgression in nature. |
