番茄果实的独特风味是糖、酸和大量挥发性化合物之间复杂相互作用的总和。虽然人们普遍认为商业化生产的番茄的味道较差，但该性状的生物化学和遗传复杂性使得育种以改善味道变得极其困难。挥发物，特别是，提出了一个主要的挑战，风味改善，从一个不同的脂质，氨基酸和类胡萝卜素前体的集合产生。很少有基因控制其生物合成已被确定。新的数量性状基因座（QTL），影响红熟水果的挥发性排放量的描述。利用栽培番茄Solanum lycopersicum与其野生近缘种S. habrochaites，特点是在多个季节和地点。共定位了30个影响一种或多种挥发物释放的QTL。从这个映射项目的数据，结合以前收集的数据，IL人口来自S。lycopersicum和S. pennellii种群，用于构建相关数据库。来自这些数据的代谢物树提供了新的见解，这些挥发物的合成途径。其中一个QTL是2号染色体上影响水果类胡萝卜素含量的新位点。从这个和其他线路的挥发性排放物表明，线性和环状的脱辅基类胡萝卜素挥发物可能来自单独的类胡萝卜素池。
The unique flavour of a tomato fruit is the sum of a complex interaction among sugars, acids, and a large set of volatile compounds. While it is generally acknowledged that the flavour of commercially produced tomatoes is inferior, the biochemical and genetic complexity of the trait has made breeding for improved flavour extremely difficult. The volatiles, in particular, present a major challenge for flavour improvement, being generated from a diverse set of lipid, amino acid, and carotenoid precursors. Very few genes controlling their biosynthesis have been identified. New quantitative trait loci (QTLs) that affect the volatile emissions of red-ripe fruits are described here. A population of introgression lines derived from a cross between the cultivated tomato Solanum lycopersicum and its wild relative, S. habrochaites, was characterized over multiple seasons and locations. A total of 30 QTLs affecting the emission of one or more volatiles were mapped. The data from this mapping project, combined with previously collected data on an IL population derived from a cross between S. lycopersicum and S. pennellii populations, were used to construct a correlational database. A metabolite tree derived from these data provides new insights into the pathways for the synthesis of several of these volatiles. One QTL is a novel locus affecting fruit carotenoid content on chromosome 2. Volatile emissions from this and other lines indicate that the linear and cyclic apocarotenoid volatiles are probably derived from separate carotenoid pools.
