BACKGROUND AND AIMS Whole genome duplication is known to influence ecological interactions and plant physiology, however, despite abundant case studies, much is still unknown about the typical impact of genome duplication on plant secondary metabolites (PSMs). In this study, we assessed the impact of polyploidy events on PSM characteristics in non-cultivated plants. METHODS We conducted a systematic review and meta-analysis to compare composition and concentration of PSMs among closely-related plant species or species-complexes differing in ploidy level. KEY RESULTS We assessed 53 studies that focus on PSMs among multiple cytotypes, of which only 14 studies compared concentration quantitatively among cytotypes. We found that whole genome duplication can have a significant effect on PSM concentration, however these effects are highly inconsistent. CONCLUSION Overall, there was no consistent effect of whole genome duplication on PSM concentrations or profiles.

基因组重复对非栽培物种次生代谢物组成的影响:系统荟萃分析

背景和目的 众所周知,全基因组复制会影响生态相互作用和植物生理学,然而,尽管有大量案例研究,但关于基因组复制对植物次生代谢产物 (PSM) 的典型影响仍有很多未知。在这项研究中,我们评估了多倍体事件对非栽培植物 PSM 特征的影响。方法 我们进行了系统评价和荟萃分析,以比较密切相关的植物物种或不同倍性水平的物种复合体之间 PSM 的组成和浓度。主要结果 我们评估了 53 项针对多种细胞类型中 PSM 的研究,其中只有 14 项研究对细胞类型之间的浓度进行了定量比较。我们发现全基因组复制对 PSM 浓度有显着影响,但这些影响高度不一致。
