One such novel idea is that (idea) of inserting into the chromosomes of plants discrete genes that are not a part of the plants' natural constitution:specifically,the idea of inserting into nonleguminous plants the genes,if they can be identified and isolated,that fit the leguminous plants to be hosts for nitrogen-fixing bacteria. Hence,(there is ) the intensified research on legumes.
這其中的一個(gè)新穎思想就是,在植物的染色體(chromosome)內(nèi)注入并非是該植物自然構(gòu)造一個(gè)部分的那些不相關(guān)聯(lián)的因基:具體而言,這一思想是,在非豆科植物內(nèi)注入這樣一些基因,倘若這些基因可被辨識(shí)出來并被分離開來,而這些基因業(yè)已使豆科植物宜于充當(dāng)那些具備固氮作用的細(xì)菌的寄主。由此,對(duì)豆科植物的研究日趨深入。
