One such novel idea is　that 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，the intensified research on legumes.

　　#一个新奇的想法/就是插入在植物的染色体中/不相关联的因基/不是该植物自然组成部分的/：具体而言/，这个想法就是/插入在非豆科植物内/这样一些基因/，如果他们能被辨识出来并被分离开来/，他们使豆科植物适合充当寄主/那些具备固氮作用的细菌的/。因此，研究深入对豆科植物的。

　　*这个句子很难理解，因为融入了太多的专业知识，但是知识要求并不高，如果以前对基因方面以及豆类植物固氮作用略知一二，理解大意还是不成问题的。
