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.

樹癌「褐根病」是怎麼傳播的?如何有效防止病害傳播?

褐根病(Brown root rot)是近年來赫赫有名、對樹木極具威脅性的敵人,除了臺港澳門等熱帶與亞熱帶地區的都市林,包括美屬西太平洋群島、日本琉球群島上的森林都受到嚴重的褐根病危害。當褐根病菌(Phellinus noxius)入侵樹木的根部組織,便會開始大肆破壞,造成木材組織的腐朽,原本堅固的根變得脆弱,影響根系吸收土壤中的養分,甚至因為支撐力下降而容易倒伏。...更多 


全球土壤線蟲食性群相與總量分佈研究

本系楊爵因助理教授參與跨國聯合研究團隊,完成首例涵蓋全球大範圍的劃時代線蟲群相研究。此計畫翻轉科學界對全球土壤線蟲食性群相與總量分佈的認知,發現高緯度地區的表土中線蟲數量最高,研究成果於今(7月25日)刊登在國際頂尖雜誌《自然(Nature)》期刊。...更多


Deciphering brown root rot disease of trees ─ The comparative and population genomics landscape of Phellinus noxius

In a joint international effort led by Dr. Isheng J. Tsai from the Biodiversity Research Center, Academia Sinica, and Dr. Chia-Lin Chung from the Department of Plant Pathology and Microbiology of National Taiwan University (NTU), who collaborated with the Japan Forestry and Forest Products Research Institute, University of Miyazaki, Japan, as well as Taiwan Agricultural Research Institute and NTU’s Department of Bio-industrial Mechatronics Engineering, a reference genome of P. noxius and high-quality assemblies of three closely related Hymenochaetales species (the wood-decomposing fungus P. lamaensis, the laminated root rot fungus P. sulphurascens and the trunk pathogen Porodaedalea pini) were released. ...Learn More


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
