Abstract
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.
摘要
背景与目的
全基因组复制已知会影响生态相互作用和植物生理学；然而，尽管有大量的案例研究，但对于基因组复制对植物次生代谢物（PSM）的典型影响，我们仍知之甚少。在本研究中，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，以比较亲缘关系密切的植物物种或在多倍体水平上存在差异的物种复合体之间 PSM 的组成和浓度。
主要结果
我们评估了 53 项专注于多种细胞型 PSM 的研究，其中只有 14 项研究在细胞型之间定量比较了浓度。我们发现，全基因组复制会对 PSM 浓度产生显著影响；然而，这些影响高度不一致。
结论
总体而言，全基因组复制对 PSM 浓度或谱没有一致的影响。
