摘要
代谢组学是一门研究生物体在环境变化后产生的小分子代谢物质变化规律的学科,作为一项新兴组学技术,在基因组学、蛋白质组学和转录组学之后逐渐发展起来.随着近年来极端天气频发,多种逆境胁迫对烟草的生长发育和品质产生严重影响,包括烟草质量下降、口感及香气特性发生变化等.本文总结了近年来烟草在响应逆境胁迫方面的代谢组学研究,涵盖生物胁迫和非生物胁迫两个方面,发现在逆境胁迫条件下,烟草中氨基酸、类黄酮以及糖类等与渗透调节和抗氧化相关的物质含量明显增加.同时,对代谢组学在鲜烟叶及烤后烟叶品质形成过程中的应用研究进行归纳,发现鲜烟叶受地域和成熟度影响较大,而烤后烟代谢物在不同品种间差异较大,高品质烟叶均表现出致香物质、类胡萝卜素降解产物和类西伯烷类物质等次生代谢物增多,这些物质能够赋予烟草独特的香气和风味,对品质提升具有重要意义.最后,对应用代谢组学研究烟草逆境生物学和品质的应用前景进行展望,以期为烟草逆境胁迫和品质提升方面的研究提供新思路.
Abstract
Metabonomics is a discipline that studies the change rule of small molecule metabolites pro-duced by organisms after environmental change.As an emerging omics technology,it has gradually developed after genomics,proteomics and transcriptomics.With the frequent occurrence of extreme weather in recent years,various adversity stresses have had serious impacts on growth,development and quality of tobacco,in-cluding the decline of tobacco quality and the changes of taste and aroma characteristics,etc.This article sum-marized the metabonomics research on tobacco defense response to stresses in recent years,covering biological and abiotic stresses.It was found that under stress conditions,the content of amino acids,flavonoids,sugars and other substances related to osmotic regulation and antioxidant activity in tobacco increased significantly.At the same time,the application researches of metabonomics in quality formation process of fresh and cured to-bacco leaves were also summarized.It was found that the metabolites of fresh tobacco leaves were greatly af-fected by geography and maturity,while that of cured tobacco leaves varied greatly among different varieties.High quality tobacco leaves showed the increase of secondary metabolites such as aroma compounds,carote-noid degradation products and siberane like substances,which could endow tobacco with unique aroma and flavor and was of great significance to quality improvement.Finally,the application of metabonomics in stud-ying tobacco stress biology and quality were prospected to provide new ideas for research on adversity stress and quality improvement of tobacco.
