近年来,由于遗传学和实验技术的迅速发展,已到了这样一个时期,高等植物的育种将会陆续出现一些重大的突破。对此作些粗略的预测,提出四个方面的问题。一、突变育种基因实变的机理由于基本上搞清楚了DNA结构,是已经相当清楚了。核苷酸顺序的破坏或个别核苷酸的变换,就会影响该基因的功能,或者甚至于使它完全失去作用。所以基因 In recent years, due to the rapid development of genetics and experimental techniques, it has come to such a period that some major breakthroughs will be made in the breeding of higher plants. Make some rough predictions on this issue and put forward four questions. First, the mechanism of mutation breeding gene consolidation Basically clear the DNA structure, is already quite clear. The disruption of the nucleotide sequence or the conversion of individual nucleotides affects the function of the gene or even disables it completely. So gene
