Cisgenesis is genetic modification to transfer beneficial alleles from crossable species into a recipient plant. The donor genes transferred by cisgenesis are the same as those used in traditional breeding. It can avoid linkage drag, enhance the use of existing gene alleles. This approach combines traditional breeding techniques with modern biotechnology and dramatically speeds up the breeding process. This allows plant genomes to be modified while remaining plants within the gene pool. Therefore, cisgenic plants should not be assessed as transgenics for environmental impacts.
顺基因作用是一种基因改造方式，用于将可杂交物种中的有益等位基因转移到受体植物中。通过顺基因作用转移的供体基因与传统育种中使用的基因相同。它可以避免连锁累赘，提高现有基因等位基因的利用效率。这种方法将传统育种技术与现代生物技术相结合，极大地加速了育种进程。这使得植物基因组能够在保持在基因库内的同时进行改造。因此，对于环境影响而言，不应将顺基因植物评估为转基因植物。
