摘　　要：用基因芯片检测鉴定离子束辐照下水稻中的差异表达基因(DEGs).结果共检测到26个上调和6个下调的差异表达基因.共表达网络分析(RiceNET)表明,这些基因都存在着直接或间接的互作网络,暗示水稻存在着以前没有充分认识的基因网络.为进一步研究植物应答离子束辐照候选基因提供了基础.A rice gene expression microarray was genes （DEGs） in two independent bombardment used to investigate the overlap differentially expressed experiments involving three ion fluences. The results showed that 26 up- and 6 down-regulated overlap genes were observed. A RiceNet co-expressed network analysis of the overlap DEGs showed the direct and indirect co-expressed linkages, which suggested some signal transduction pathways should be involved in this response, but the situation remains unclear. The microarray data revealed the general and key genes responding to the stress of bombardment with low-energy ion beams during rice germination, and provided information on the candidate genes for further eluci- dation of the molecular mechanisms biological effects underlying the ion-beam bombardment.
