中文摘要 | 摘要 為加速水稻病蟲害抗性研究,以四個生 物基因組資料庫(Oryzabase, Gramene, dbEST, KOME)的生物資訊為基礎,對水稻 五種重要病蟲害(稻熱病、紋枯病、白葉枯 病、褐飛蝨、白背飛蝨)的抗性基因組研究, 如抗性基因、數量性狀基因座(QTL)、表現 序列標幟(EST)及全長cDNA(FL-cDNA)的 註冊情形進行了初步統計,並就相關進展加 以綜述討論。透過多個生物資料庫的搜尋和 資料整理分析顯示,目前這五種重要水稻病 蟲害抗性基因及其QTL,均已被陸續鑑定 出來,病害方面以水稻抗稻熱病基因相對較 多,蟲害則以水稻抗褐飛蝨基因較多;但僅 有受稻熱病及褐飛蝨誘導之水稻EST 和 FL-cDNA 已登錄有序列資料。到2005 年5 月31 日為止,NCBI 的dbEST 資料庫中受 稻熱病誘導之水稻EST 有85,105 條,佔其 所有水稻EST 之22%,而褐飛蝨誘導之水 稻EST 則僅有188 條。在KOME 資料庫中 受稻熱病、褐飛蝨誘導之水稻FL-cDNA 各 有9、11 條,數量甚微,不到其所有水稻 FL-cDNA 之0.04%。 |
英文摘要 | ABSTRACT To promote the development of the disease/pest resistance research in rice, a highlight of information on rice genomics was presented. We searched, collected and integrated the rice genome information of five major diseases and pests (blast fungus, sheath blight, bacterial blight, brown planthopper and white-backed planthopper) in rice from four public databases (Oryzabase, Gramene, dbEST and KOME). The data of major resistant gene, quantitative trait locus (QTL), expressed sequence tag (EST) and full length cDNA (FL-cDNA) from multiple public databases were summarized in statistics that allow the researchers to easily understand the current progress in rice disease/pest resistance genomics research. The perspective in these fields was also discussed. So far, many major genes and many QTLs in rice resistant to five diseases and pests have been detected, especially for blast fungus and brown planthopper resistance in rice. However, only ESTs and FL-cDNA in rice resistant to blast fungus and brown planthopper were found. Up to May 31, 2005, the dbEST of NCBI has recorded 85,105 rice ESTs induced by blast fungus, which occupied 22% of total rice ESTs. Only 188 rice ESTs induced by brown planthopper were found in dbEST. Only a few of FL-cDNA in rice ESTs induced by blast fungus and brown planthopper, being 9 and 11 pieces,obtained from KOME database (less than 0.04% of rice FL-cDNA). |
