Abstract: Genome, transcriptome, proteomics, metabonomics technology are the important means to study the gene, protein and small molecular etc. substances, when the organisms encounter the internal and external environment disturbance. They are widely applied in botany, microbiology, food safety, etc. fields. This paper expounded the application of monomics in studying different varieties, ecological environment, stress, functional genes, flavor, organ of tobacco. Then the advantages and disadvantages of each monomics were analyzed, and the function of multiple monomics conjoint analysis technique in up-grading quality of tobacco leaves was introduced. The paper also prospected the future research and application, so as to provide experience and reference for further study on molecular mechanism of tobacco quality.

Key words: tobacco, genome, transcriptome, proteome, metabolome

摘要： 基因组、转录组、蛋白组、代谢组学技术作为研究生物体受到内外环境扰动后基因、蛋白和小分子等物质的重要手段，被广泛应用于植物学、微生物学、食品安全等领域。综述了单组学技术在研究不同品种、生态环境、胁迫、功能基因、香型、器官条件下的烟草差异变化机理的应用。最后对各组学优缺点进行了分析，介绍了多组学联合分析技术在提升烟叶品质研究中的作用，并对下一步的研究和应用进行了展望，以期为烟草品质的分子机理研究提供借鉴与参考。
