番茄果实的发育和成熟受到了相当多的关注，因为这一过程对植物生物学的独特性以及这些果实作为人类饮食组成部分的重要性。果实发育的分子和遗传分析，特别是肉质果实的成熟，近年来在知识方面取得了重大进展。关于乙烯的生物合成和反应、细胞壁代谢以及影响成熟的环境因素（如光），人们已经收集了大量的知识。对支撑这些反应的一般代谢变化的直接关注要少得多。鉴于果实代谢的巨大复杂性，本综述选择的重点是初级代谢物和那些对果实质量重要的次生代谢物。本文就近年来番茄代谢途径的研究进展进行综述。还讨论了最近的例子，其中结合应用代谢和转录分析，旨在确定候选基因修改代谢物的内容，被使用。
The development and maturation of tomato fruits has received considerable attention because of both the uniqueness of such processes to the biology of plants and the importance of these fruits as a component of the human diet. Molecular and genetic analysis of fruit development, and especially ripening of fleshy fruits, has resulted in significant gains in knowledge over recent years. A large amount of knowledge has been gathered on ethylene biosynthesis and response, cell wall metabolism, and environmental factors, such as light, that impact ripening. Considerably less attention has been paid directly to the general metabolic shifts that underpin these responses. Given the vast complexity of fruit metabolism, the focus chosen for this review is on primary metabolites and those secondary metabolites that are important with respect to fruit quality. Here, recent advances in dissecting tomato metabolic pathways are reviewed. Also discussed are recent examples in which the combined application of metabolic and transcriptional profiling, aimed at identifying candidate genes for modifying metabolite contents, was used.
