Introduction

The Department of Plant Pathology and Microbiology is a centre for research in the plant diseases and microbiology at National Taiwan University. It is committed to basic research in plant pathology and microbiology as well as to the application of plant protection and microbial resources.

The Department of Plant Pathology and Microbiology at National Taiwan University was officially established in 2003. Over the years, the Department has developed well-balanced research, extension and teaching programs that emphasise applied plant disease management and a pursuit of new knowledge of use in controlling plant diseases.

The department offers BS, MS, and PhD degree programs with a current enrolment of 120 undergraduate and 50 graduate students. For prospective students, postdoctoral scientists and visiting scholars, our department offers exclusive opportunities throughout the country to work with a broad range of crops and plant diseases of national and international importance.

The mission of our department is to engage in excellence research, education, and outreach in plant pathology and microbiology with importance on the understanding of relationships among microbes, their hosts, and the environment, and on the management of diseases and other threats impacting agricultural and natural ecosystems, food safety, and human and environmental health. Our faculty is focused on professional priorities for novel research, excellence in mentoring of students, and productivity in scholarship and outreach service to society. We strive for the highest commitments to creativity, honesty, and mutual respect.

解密樹木褐根病 ─ 有害木層孔菌基因體發表

中央研究院生物多樣性研究中心蔡怡陞助研究員及臺灣大學植物病理與微生物學系鍾嘉綾副教授領導的研究團隊,與農業試驗所植物病理組、臺大生機系及日本獨立行政法人森林綜合研究所 (FFPRI) 聯手合作,首次定序引起樹木褐根病的有害木層孔菌 (Phellinus noxius) 及另三種近緣真菌基因體,探討P. noxius可能的致病遺傳機制,及褐根病在台灣及日本離島的傳播途徑,這些結果可望提供深入研究此類真菌病原特性的新基礎。該研究於2017年9月19日發表在國際期刊《分子生態學》(Molecular Ecology)。...更多


鈣離子真的這麼重要嗎!? 植物病原篇 (劉瑞芬老師實驗室 胡芳瑜)

鈣離子在各種生物扮演次級傳訊者的角色,一旦接收到外界的刺激,為了要快速把訊息傳遞到細胞運作的核心,這時候就需要擴散快速且數量眾多的小尖兵-鈣離子出現啦~他們可以迅速地把外界的刺激放大並傳遞到下游的訊息接收者。因此,細胞內鈣離子濃度上升或是下降都可以看作是開啟下一步反應的開關,然後像大隊接力一般,鈣離子所捎來的訊號被一步步往下傳遞,最終傳到細胞核內的轉錄因子後,便可啟動相關基因的表現。...更多


源自百合防禦相關蛋白的抗菌胜肽(陳昭瑩老師實驗室 林家華博士)

生物具備多重防禦機制以抵抗病原微生物所造成的感染,普遍存在於原核與真核生物表皮組織或細胞表面的抗菌胜肽屬於植物防禦的第一防線,負責阻止或殺滅病毒、細菌、真菌、線蟲等入侵微生物,為天然之植物免疫反應。百合葉部防禦相關蛋白LsGRP1鑑定自葵百合經水楊酸處理的植株,其LsGRP1C區段具有廣泛抑菌圖譜之抗菌活性,能透過破壞微生物細胞膜、誘發真菌之程序性細胞死亡等機制殺滅微生物。...更多


百慕達草白葉病菌質體的基因體分析(林長平老師實驗室 卓舒婷)

百慕達草白葉病 (Bermuda grass white leaf) 是由一種透過媒介昆蟲傳播的細菌性植物病原所導致的疾病,於1972年首先在台灣發表。受感染的植株會出現白葉、節間縮短等病徵,甚至是死亡。這類叫做「植物菌質體 (phytoplasma)」的病原菌擁有極小的細胞和僅僅數百個基因,但能夠感染的宿主範圍卻很廣。其生存區域侷限在宿主植物的韌皮部以及媒介昆蟲體內,截至目前為止仍然無法被在實驗室中純化培養,因此長期以來我們對於植物菌質體的研究一直面臨很大的困難。...更多


抗Potyvirus屬植物病毒之廣效性抗體之研發(張雅君老師實驗室 劉漢麟博士)

Potyvirus屬病毒為重要的植物病毒屬之一,根據ICTV正式命名的病毒數目已多達162種。此屬病毒能夠經由蚜蟲或機械傳播,且屬內某些病毒的寄主廣泛,造成嚴重的經濟損失。為了能夠降低農損與防止病毒傳播,研發有效率且低費用的病毒檢測方法是重要的課題之一。...更多
