Genome duplication impact on secondary metabolite composition in non-cultivated species: A systematic meta-analysis.

Genome duplication is known to influence herbivore interactions and plant physiology; however, despite abundant case studies, much is still unknown about the impact of genome duplication on secondary metabolites in relation to defense. We aimed to identified whether there is a relationship between increased genome size and secondary metabolite production in non-cultivated species. To assess the relationship between genome size and secondary metabolite production, we conducted a systematic meta-analysis comparing secondary metabolite production between closely-related species or species-complexes differing in genome size. Despite the abundant studies on chemosystematics of polyploids, few studies have measured the abundance of shared secondary metabolites between polyploids and closely related diploids. Based on relevant studies, we found that whole genome duplication does not affect secondary metabolites in naturally occurring populations in a consistent manner.
