　　研究方向

　　植物中合成丰富多样的特异性天然产物，对于植物自身的天然防御、适应性和发育具有重要意义，其中很多在人类的农业生产和健康营养中有着不可替代的应用价值。植物如何合成这些特异性天然代谢物是植物学研究中一个重要的方面，为他们的合成生物学应用提供理论基础。本课题组利用转录组、基因组和化学分析为主要手段，配合细菌、酵母、植物等多种表达体系，解析对于农艺性状和人类健康有重要应用价值的天然代谢物的合成途径，一方面利用分子遗传学手段改变农作物的代谢相关农艺性状，促进农业生产的发展；另一方面利用合成生物学理念和代谢工程手段，异源重组代谢途径，以达到大规模生产具有经济价值的天然代谢物的目的。

 

　　研究进展

　　利用转录组学测定和共表达分析、烟草瞬时表达和化学测定等手段，对植物天然杀虫代谢物除虫菊酯在植物中的代谢途径进行较为全面的解析。作者和其合作者先后解析了除虫菊中除虫菊酯配体：茉莉醇酮（Jasmolone）、除虫醇酮（Pyrethrolone）、第二菊酸（Pyrethric acid）等化合物相关合成酶和合成过程，并在烟草中进行了初步的合成生物学构建和检测 (Li et al, Plant Physiology, 2019; Li et al, Plant Physiology, 2018; Xu et al, New Phytologist, 2019)。

　　Research Interest

　　Plant synthesizes specialized metabolism with a vast of diversity and peculiarity. Most of them are important for defence, adaption and development of plant itself. Human are using many of those plant specialized metabolism for agricultural and health purpose. Elucidation of plant specialized metabolism and using those knowledges acquired for synthetic metabolic engineering is important for application. Our group uses transcriptome, genome, chemical analysis and multiple exogenous expression system (including bacteria, yeast and plant), to elucidate the biosynthesis pathway of plant specialized metabolism which are important for both agriculture and human health, on one hand improving crop traits related to metabolites via genetic methods, on the other hand using synthetic metabolic engineering by exogenously reassemble metabolic biosynthesis pathway to produce valuable metabolites in large scale.

　　

　　Major Achievements

　　The biosynthesis pathway of natural pesticide pyrethrins in Tanacetum cinerariifolium was comprehensive deciphered, via methods including transcriptome and coexpression analysis, tobacco transient expression and chemical analysis etc. We and our collaborator elucidated the enzymes and reactions worked for biosynthesis of pyrethrins moieties: jasmolone, pyrethrolone and pyrethric acid, and did primary test for synthetic metabolic engineering (Li et al, Plant Physiology, 2019; Li et al, Plant Physiology, 2018; Xu et al, New Phytologist, 2019).
