水稻细胞质雄性不育的分子机制研究——不育系、保持系苗期基因表达差异初步探讨

STUDIES ON MOLECULAR MECHANISM OF RICE CYTOPLASMIC MALE STERILITY ——Preliminary studies on seedlings gene differential expression between sterile lines and their maintain lines

应用ｍＲＮＡ差异显示技术研究了珍汕９７、马协和丛广４１等３套水稻细胞质雄性不育系（Ａ）及保持系（Ｂ）在二叶苗期基因表达情况，发现这３套材料的不育系和保持系在苗期都存在着基因表达的差异，且基因表达的差异情况各有特点．

Seedlings gene differential expression between rice cytoplasmic male sterile lines and their maintain lines of Zhenshan 97,Maxie and Congguang 41 was found by applying mRNA differential display.And there are different features in gene differential expression.This paper preliminarily analyses the result and further discusses the complex mechanism of interaction between nuclear and cytoplasmic gene in cytoplasmic male sterility.
