科技部专家组不久前宣布,黑龙江大学郭德栋教授主持的课题组已成功地从野生甜菜中分离出带有无融合基因的单个染色体。这一成果表明,我国植物克隆技术已居世界领先水平。 无融合生殖也叫植物克隆,是指植物在不需雄雌细胞结合的情况下所进行的单体无性繁殖。该项目是国家自然科学基金和国家转基因计划专项课题。郭德栋教授在对野生甜菜进行的杂交实验中,成功分离出无融合生殖甜菜单体染色体,并从这个染色体中发现了无融合克隆基因,这也是世界上第一次将无融合基因确定在一个染色体上。这一成果是由以中科院院士范云六教授为组长的科技部专家小组进 Not long ago, the group of experts of the Ministry of Science and Technology announced that a research group led by Professor Guo De-Dong of Heilongjiang University has successfully isolated a single chromosome with a non-fusion gene from wild beet. This result shows that China’s plant cloning technology has been the world’s leading level. Apomixis, also known as plant cloning, refers to the vegetative propagation of a plant in the absence of male and female cells. This project is a special subject of National Natural Science Foundation of China and national gene transfer program. In his experiment on hybridization of wild sugar beet, Professor Guo Degong successfully isolated the chromosomes of apomictic beet monomer and found apomixis cloning genes from this chromosome. This is the first time in the world that the apomixis gene is identified in one chromosome on. This achievement is made by a team of experts from the Ministry of Science and Technology headed by Professor Fan Yunli, a member of the Chinese Academy of Sciences
