一、前言早在1908年,科伦斯(Correns)就首次从遗传的角度对细胞质进行了研究。他研究的是蓟属(Girsium)的两个种(Correas,1908)。通过下列连续的回交,他发现,C.oleaceum的单性别性状(母系)是由细胞质而不是由核基因决定的。
I. INTRODUCTION As early as 1908, Correns first studied the cytoplasm from a genetic point of view. He studied two species of the genus Girsium (Correas, 1908). Through the following successive backcrosses, he found that the single-sex trait (maternal line) of C. oleaceum is determined by the cytoplasm rather than the nuclear gene.
