Keynote Speakers

The information about the Keynote Speakers of ICASB2022 are as follows, which will be updated regularly.

Dr. Xingang Liu, Professor
Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing, China

Biography: Dr. Xingang Liu got his Ph.D. degree in applied chemistry in 2006 from Tianjin University. He has been Assistant Professor from 2006 to 2008, Associate Professor from 2009 to 2013, and Professor from 2014 to now. He was a visiting scholar at the University of Minnesota from Sep. 2018 to Sep. 2019. He has mainly researched Chemical analysis of pesticide residue, the environmental behavior of pesticides, and pesticide pollution prevention and control, etc.

Topic: Degradation and Risk of Fungicides in Water and Soil

Abstract: Difenoconazole is a widely used triazole fungicide that has been frequently detected in the environment. Here, laboratory experiments were conducted to investigate the degradation kinetics, pathways, and toxicity of transformation products of difenoconazole. 12, 4 and 4 TPs generated by photolysis, hydrolysis and soil degradation were identified via UHPLC-QTOF/MS and the UNIFI software. Four intermediates TP295, TP295A, TP354A and TP387A reported for the first time were confirmed by purchase or synthesis of their standards, and they were further quantified using UHPLC-MS/MS in all tested samples. ECOSAR prediction and laboratory tests showed that the acute toxicities of four novel TPs on Brachydanio rerio, Daphnia magna and Selenastrum capricornutum are substantially lower than that of difenoconazole, while all the TPs except for TP277C were predicted chronically very toxic to fish, which may pose a potential threat to aquatic ecosystems. The results are important for elucidating the environmental fate of difenoconazole and assessing the environmental risks, and further providing guidance for scientific and reasonable use.

Dr. He Yan, Associate Professor
College of Plant Protection, Northwest A&F University, Yangling, China

Biography: Dr. He Yan is currently an associate professor at Northwest University of Agriculture and Forestry Science and Technology. Dr. Yan received his doctorate from Kunming Institute of Botany, Chinese Academy of Sciences. In 2018, Dr. Yan becomes an associate professor in the school of plant protection, at Northwest University of Agriculture and Forestry Science and Technology. His research interests include the discovery and mechanism of action of natural products with antifungal activity and design, synthesis and biological activity of natural products based derivatives. Dr. Yan has written more than 30 peer-reviewed publications and 12 patents. Dr. Yan is a member of China Agricultural Chemistry Society, China insect society and China plant protection society. She is an active commentator in many journals, books, and conferences. Dr. Yan was invited to deliver more than 10 speeches at domestic and international conferences and has won many national and international awards from different professional associations and organizations.

Topic: Development and Application of New Plant Immune Inducers

Abstract: Plant immune inducers have the ability to improve crop resistance and effectively prevent and control crop diseases, which meets the needs of the development of green agriculture. At present, several large agrochemical companies in the world have successively developed commercialized plant disease resistance inducers. The research and utilization of plant immune inducers have been recognized by relevant government management and promotion departments and farmers. Inducers play an increasingly important role in protecting the healthy growth of plants and ensuring food and ecological safety. With the support of the national key R & D Program (2017yfd0200900), we carried out the screening of plant disease resistance induced by biological sources, the separation of active components and the related research on the action mechanism. More than 300 kinds of plant extracts were screened successively to induce plant disease resistance activity, and the separation of active components and action mechanism of highly active plant extracts such as Coptis Chinensis, Chelidonium majus, Citrus reticulata, Phyllanthus Emblica, and Litsea cubeba were studied. A variety of elicitors with prominent activity in inducing plant disease resistance have been reported successively, such as alkaloids represented by berberine, chelidonine and reticine an (active component of inducing resistance in the citrus peel), phenolic acids represented by corilagin, sugars and proteins represented by gp1pro protein, leiwan polysaccharide and pullulan polysaccharide. Published 12 academic papers and applied for 9 invention patents of the people's Republic of China. These studies laid a foundation for the development of new plant immune inducers. This speech will discuss the latest important achievements in the discovery, mechanism of action and product development of leading compounds that induce plant immunity.
