3、代谢组学在农业和食品安全中的应用

Metabolomics applications in agricultureand food safety

代谢组学致力于全面、系统地对生物体内的小分子代谢物进行定性和定量分析,从而揭示其生理功能和代谢表型之间的关系。代谢组学在植物生理生化、抗逆胁迫机制及新品种培育及食品安全等领域已有广泛应用。本课题组围绕国家重大需求和领域热点问题开展新方法及其在农业和食品安全等领域应用研究。

Metabolomicsis the unbiased simultaneous identification and quantification of metabolomes. Metabolites are the end products of cellular functions, and their levels can be viewed as the response of biological systems to environmental or genetic manipulation. Metabolicalternations reflectthe changes occurring during plant growth, development, and in response to stress. Metabolomics are aimed at linking between genotypes and phenotypes. Current studies have shown metabolomics can help us to understand the various physiological and biochemical changes occurring in the plants and their influence on the phenotype.

Our research interestsare focused on:

(a)The development of plant metabolomics analytical methods

(2)Metabolomics in assessing plant phenotypes and genetic diversity

(3)Metabolite signatures of genetically modified crops

(4)Metabolomics for plant stressresponse

(5)Metabolomics in food safety
