对温敏型叶绿素突变体进行遗传分析表明,离子束诱变的水稻温敏型叶绿素突变体苗期叶片黄化性状是以一对隐性核基因为主,核质互作遗传;其叶绿体在超微结构上表现为基粒数少,基粒类囊体片层数目少,发育滞后,叶绿体缺少明显的双层膜结构。
The genetic analysis of the thermo-sensitive chlorophyll a mutant showed that the leaf yellowing trait of rice thermo-sensitive chlorophyll mutant by ion beam mutagenesis was dominated by a pair of recessive nuclear genes, On the ultrastructure, there are few basal grains, few stratum granulosum lamellae, lagging development and lack of obvious bilayer membrane structure in chloroplast.
