水稻白葉枯病抗性突變體接種白葉枯病菌之轉錄體學研究

Abstract

白葉枯病是由＂Xanthomonas oryzae pv. oryzae＂所引起的水稻嚴重病害。本研究為了開發新的抗性基因，利用「台農67號」（'TNG67'）及具持久抗性之SA0423突變體為材料，接種台灣水稻白葉枯病抗性檢定圃專用菌株XF89b，並利用微陣列晶片分析接種後之轉錄體變化。 Bacterial blight disease, caused by ＂Xanthomonas oryzae pv. oryzae＂, is one of the most serious diseases in rice. To explore novel resistant genes in SA0423, harbored with broadly resistance against rice bacterial blight disease (RBBD), the transcriptomes of 'TNG67' and SA0423 were determined by microarray technologies with the RNA samples prepared from the leaves collected at 0, 0.5, 1, 2, and 6 h, respectively, after inoculation of XF89b, atypical isolate used in Taiwan nursery.
