中文摘要
本研究着重于诱变方向的研究,以期提高植物诱变育种的效率。蔗糖处理提高了拟南芥花色素苷合成相关基因的表达水平。离子束辐照诱导的色素缺失突变体的频率在蔗糖处理的幼苗中高于未处理的幼苗。这表明高表达基因相对可变的可能性。
英文摘要
This study focused on the direction of mutation in order to improve the efficiency of plant mutation breeding. The expression level of Arabidopsis genes involved in anthocyanin biosynthesis was elevated by sucrose treatment. The frequency of pigment-less mutants induced by ion beam irradiation was higher in sucrose-treated seedlings than in non-treated seedlings. This suggests the possibility that the highly-expressed genes are relatively mutable.
