植微系副教授楊爵因長年致力植物保護學 獲110年度吳大猷先生紀念獎肯定

 

        台大植物病理與微生物學系副教授楊爵因長年致力研究植物寄生性線蟲,不僅發現我國新紀錄種草莓根腐線蟲,並透過田間監測建立預測模型,面對長期困擾農民的水稻病蟲害,楊爵因研究室更開發檢測技術,能偵測躲藏於幼苗中的線蟲和病菌,對植物病蟲害防治貢獻良多,也獲得110年度科技部「吳大猷先生紀念獎」殊榮。

        科技部為培育青年研究人員,獎助並鼓勵國家未來學術菁英長期投入學術研究與持續提升學術表現,同時紀念物理學家吳大猷對發展科學與技術研究之貢獻,自2000年起設立「吳大猷先生紀念獎」。該獎項由科技部主動遴選年齡42歲以下之副教授、副研究員或相當職級以下執行科技部專題研究計畫之主持人,頒予獎項給研究表現優異者。

植微系副教授楊爵因。

 

        楊爵因於植物保護學領域研究傑出,教學與服務不遺餘力,而她更是全球少數致力於植物寄生性線蟲研究的學者。

植物寄生性線蟲為重要的農林業病原害蟲,每年於全球造成近5兆台幣的經濟損失。然而,植物寄生性線蟲身體細小且透明,肉眼難以直接看見,且諸多種類為絕對寄生且行兩性交配,欲進行相關研究頗具挑戰性。

        楊爵因2015年成立「線蟲與微生物生態學研究室」,從永續農業的角度出發,在植物病理的紮實基礎上,併用新穎的分子生物學與傳統植物病原微生物技術,進行應用導向型的基礎研究,逐步開發綜合病蟲害防治管理策略。

        該研究室長年於全國各處進行土壤線蟲族群與相關植物病害的調查,還發現我國新紀錄種草莓根腐線蟲,並透過田間監測研究線蟲族群於田區的族群動態變化,以及分析諸多環境因子與族群密度消長的關聯性,最終建立可預測田間線蟲族群的模型與恰當的輪作方法,作為防治此種害蟲的重要參考。

        此外,面對長期困擾農民的水稻病蟲害,楊爵因的研究室選擇運用恆溫圈環形核酸增幅分子偵測技術,開發高專一性且敏感的水稻白尖病和徒長病快速檢測技術。該技術可偵測出躲藏於幼苗中的線蟲和病菌,不僅能運用於水稻育苗期,也能作為我國進口植物與相關產品之植物檢疫之工具,有利於國內外水稻重要病害的提早發現與防範。

        不僅如此,楊爵因更發現我國新種真菌Paraboeremia taiwanensis Samsoniella sp.具有良好的寄生線蟲能力,能有效降低根瘤線蟲所造成的植物病害,且防治效果與國際市售之生物防治製劑相當,具備開發潛力,能適用於台灣生物防治資材。

Asso. Prof. Jiue-in Yang in the Department of plant pathology and microbiology recognized as awardee of Wu Ta-You Memorial Award

 

        In honor and memory of Dr. Ta-You Wu for his contribution to the development of science and technology, the Ministry of Science and Technology (MOST) has established the Ta-You Wu Memorial Award. Since 2002, the award is given to nurture young researchers under the age of 42, and is bestowed upon individuals who have dedicated themselves to long-term outstanding research work. We are glad to share the news that Asso. Prof. Jiue-in Yang in the department of plant pathology and microbiology is recognized with this year’s award in her excellence in plant protection research.

        Asso. Prof. Yang is one the very few scientists working with plant parasitic nematodes, a group of microscopic pests that damage forest and crops intensively and contribute to over $150 billion USD yield loss each year. Being transparent in the soil and living an obligate parasitism life style, plant parasitic nematodes are very challenging to work with.

        Nevertheless, with the passion of nematodes and sustainable agriculture, the Nematology and Microbial Ecology Laboratory aiming to develop integrated pest management strategies for plant parasitic nematodes was established in 2015 by Dr. Yang, and had been since conducting application-oriented research using both modern molecular biotechnologies and traditional phytopathological methods.

        Throughout the past 6 years, the Yang lab conducted large-scale field survey and mapped the soil nematode population and related plant disease distribution in Taiwan. They discovered the strawberry root lesion nematode in strawberry fields, and developed population prediction crop rotation model after months of nematode population and environmental factors surveillance and analysis.

        On the other hand, for the diseases that had long been troubling rice growers, the Yang lab developed a fast, highly specific and sensitive LAMP detection assay for both white-tip and Bakana diseases; The assays allow early detection of the disease at seedling stage, and could not only prevent the ill plants entering the field but also serve as great tool for border quarantine inspections.

         Last but not least, the Yang lab discovered the nematode-parasitic abilities for two new local isolated fungi,Paraboeremia taiwanensis and Samsoniella sp.are equivalent to commercialized products, that are with great potential for bio-pesticide development.

        Asso. Prof. Yang’s outstanding dedication to plant protection research and teaching is inspiring. We are proud of her recognition by the Wu Ta-You Memorial Award by MOST.  

Asso. Prof. Yang’s research has been published in "Nature".
