由于剧毒病原体基因型的选择，植物中抗病基因的功效随着时间的推移而降低。作物保护计划的一个关键目标是提高这些基因所赋予的抗性的持久性。植物抗病基因的空间和时间分布被认为是决定其耐久性的主要因素。在文献中，四种主要策略结合时间和空间上的抗性基因被认为可以延缓剧毒病原体基因型的进化。我们回顾了这篇文献，目的是确定哪种部署策略可以实现抗性基因的最大持久性。尽管比较一种以上抗性基因的部署策略的理论和实证研究非常缺乏，但它们表明，可以通过将抗病基因组合在同一植物中（金字塔）来提高抗病基因的整体耐久性。田间监测数据的回顾性分析还表明，植物内抗病基因的金字塔化是最持久的策略。通过扩展，我们建议将抗病基因与其他病原体控制实践（农药、耕作实践）相结合可能是减缓剧毒病原体基因型进化的相关管理策略。
The efficacy of disease resistance genes in plants decreases over time because of the selection of virulent pathogen genotypes. A key goal of crop protection programs is to increase the durability of the resistance conferred by these genes. The spatial and temporal deployment of plant disease resistance genes is considered to be a major factor determining their durability. In the literature, four principal strategies combining resistance genes over time and space have been considered to delay the evolution of virulent pathogen genotypes. We reviewed this literature with the aim of determining which deployment strategy results in the greatest durability of resistance genes. Although theoretical and empirical studies comparing deployment strategies of more than one resistance gene are very scarce, they suggest that the overall durability of disease resistance genes can be increased by combining their presence in the same plant (pyramiding). Retrospective analyses of field monitoring data also suggest that the pyramiding of disease resistance genes within a plant is the most durable strategy. By extension, we suggest that the combination of disease resistance genes with other practices for pathogen control (pesticides, farming practices) may be a relevant management strategy to slow down the evolution of virulent pathogen genotypes.
