Genome-scale analyses of variation, gene expression, and metabolite accumulation in ancestral, early domesticates, and modern tomatoes by Zhu et al. identify genes underlying fruit chemistry and demonstrate that alleles affecting metabolic quality have been bred into modern varieties as a result of linkage drag. Similar metabolic hitchhikers are likely ubiquitous in other domesticated species.

番茄基因组学揭示了作物驯化和改良的后果。

Zhu等人在祖先，早期驯养和现代番茄中进行变异，基因表达和代谢产物积累的基因组规模分析。鉴定水果化学基础的基因，并证明影响连锁质量的等位基因已因连锁拖累而被育成现代品种。在其他驯养物种中，类似的代谢搭便车者也很普遍。
