微生物分子遺傳學研究室

植物病原細菌學、細菌遺傳學、分子生物學

        實驗室主要目標在於利用核酸相關技術與次世代定序為植物病害防治帶來更多可能性，包含分析目標細菌染色體、不同環境微生物相及代謝物產生情形，並分析細菌性條斑病基因型分群與各水稻品中間抗感病之關係。

        植物病原細菌在台灣因氣候及環境適宜，可造成多種植物病害，如 Ralstonia solanacearum 所引起之青枯病及由 Xanthomonas 屬細菌引起之多種作物細菌性斑點病，其傳播快速加上防治困難，在田間已造成農民重大損失。青枯病與番茄萎凋病分別為細菌及真菌所造成之番茄系統性病害，兩者皆為土壤傳播病害，難以使用化學藥劑防治，為達永續農業之目的，合理使用化學藥劑並同時發展可替代性物質已成為各相關單位之共同目標。實驗室以次世代定序技術研究有無發生青枯病之土壤微生物相差異，試圖由大數據中解讀可用於病害防治之相關因子，以達到病害防治之目的。另分析已知可防治番茄萎凋病之枯草桿菌屬 (Bacillus spp.) 細菌 BM02 之代謝物成分，並分析其調控植物基因表現情形，試圖釐清其抑病能力可能機制為何。

        病害防治除可由病原菌及環境著手，寄主植物亦為其關鍵之一，快速、正確的檢測方法可提供健康種苗以供農民使用，避免初次感染源進入本田，降低病害發生的機率，另可防止新興病害藉由國際種子貿易進入台灣，並有助種子出口貿易進行，實驗室近年鑑定多種台灣新細菌性植物病害，並研究其病原生態，開發檢測相關技術，以加強病害診斷之鑑別度與防止病害的大發生。

       水稻為台灣重要糧食作物，細菌性條斑病 (X. oryzae pv. oryzicola) 於 2005 年在台中發現，已逐漸蔓延全台，為了解各水稻品種對本病抗感病性，透過核酸多型性分析並結合田間接種試驗結果，期許可釐清本病於我國蔓延之原因並找出適宜的防治策略。

1. 結合細胞生物學、分子生物學及遺傳分析等技術研究植物病原細菌致病機制及寄主植物與病原細菌之交互作用，並開發有效之病害管理方式。
2. 台灣新興細菌性病害病因學研究 (etiology)，並針對台灣細菌性病害開發可應用於植物檢疫或健康種苗相關技術。
3. 以基因體學 (genomics) 探討土壤細菌之生物防治特性

1. 枯草桿菌屬細菌 (Bacillus spp.) 全基因體解序與其抑病能力之探討。
2. 土壤微生物或其蛋白質應用於植物病害防治之可能機制探討。
3. 水稻細菌性條斑病菌 (Xanthomonas oryzae pv. oryzicola) 與水稻白葉枯病菌 (X. oryzae pv. oryzae) 之基因分型及水稻品系抗病反應探討。
