Abstract

Intraspecific genetic diversity is an important component of biodiversity. A substantial body of evidence has demonstrated positive effects of plant genetic diversity on plant performance. However, it has remained unclear whether plant genetic diversity generally increases plant performance by reducing the pressure of plant antagonists across trophic levels for different plant life forms, ecosystems and climatic zones. Here, we analyse 4702 effect sizes reported in 413 studies that consider effects of plant genetic diversity on trophic groups and their interactions. We found that that increasing plant genetic diversity decreased the performance of plant antagonists including invertebrate herbivores, weeds, plant-feeding nematodes and plant diseases, while increasing the performance of plants and natural enemies of herbivores. Structural equation modelling indicated that plant genetic diversity increased plant performance partly by reducing plant antagonist pressure. These results reveal that plant genetic diversity often influences multiple trophic levels in ways that enhance natural pest control in managed ecosystems and consumer control of plants in natural ecosystems for sustainable plant production.

植物遗传多样性影响多个营养水平和营养相互作用。

种内遗传多样性是生物多样性的重要组成部分。大量证据表明，植物遗传多样性对植物生产性能有积极影响。然而，在不同的植物生命形式、生态系统和气候带的营养水平上，植物遗传多样性是否通过降低植物拮抗剂的压力来提高植物的性能，目前尚不清楚。在这里，我们分析了413项研究中报告的4702个效应值，这些研究考虑了植物遗传多样性对营养群及其相互作用的影响。研究发现，植物遗传多样性的增加降低了无脊椎食草动物、杂草、植食线虫和植物病害等植物拮抗剂的性能，而提高了食草动物的植物和天敌的性能。结构方程模型表明，植物遗传多样性通过降低植物拮抗剂压力来提高植物的生产性能。这些结果表明，植物遗传多样性通常影响多个营养水平，从而加强管理生态系统中自然害虫的控制和自然生态系统中植物的消费者控制，以实现植物的可持续生产。
