摘　　要：以水稻光温敏核不育系安农810S的自然淡黄叶突变体安农标810S及其野生型为材料,运用cDNA芯片技术,分析突变体和野生型的基因差异表达。结果表明,突变体有40多个与叶绿体蛋白相关的基因表达量明显增加,但是只有一个与叶绿体色素相关的基因即编码衰老诱导叶绿体延缓绿色蛋白(SGR)的基因野生型表达量明显大于突变体,这可能是突变型叶色变黄的原因。The differences in gene expression were analyzed between a natural yellowish leaf mutant, Annong Biao 810S and its wild type Annong 810S, a PTGMS line in rice by using cDNA microarrays. The results showed that in the mutant type, more than forty chloroplast protein related genes had an up-regulated expression while only one gene, i.e. , the gene encoding the senescence-inducible chloroplast stay-green protein （ SGR）, had a remarkable down-regulated expression, indicating that the leaf yellowing might result from the low expression of the gene SGR in the mutant type rice.
