摘要: 植物表面和内部组织中的微生物在植物的生长、发育、适应和多样性中发挥着至关重要的作用。大量研究证实了植物相关微生物组的巨大功能潜力,但尚不清楚植物相关微生物组是如何在植物进化过程中构建的。从植物系统发育、作物驯化中植物-微生物组进化轨迹,以及宿主约束下微生物之间互作进化的研究进展入手,概述了植物及其微生物组的生态适应和进化机制。了解植物-微生物组相互作用的进化驱动因素,有利于恢复植物与微生物原始的有益协作关系,从而达到提高作物养分吸收、产量和品质等高产高效目标。强调未来通过分子生物学和作物基因组学相结合的策略,将是调控植物微生物组以促进农业可持续发展的关键,同时,对植物-微生物组互作的生态进化研究方向进行了展望。

Abstract: Microorganisms thriving at the plant surfaces and internal tissues play critical roles in plant growth,development,adaptation,and diversification. Numerous studies have revealed the great functional capacity of plant-associated microbiome,however,it is not clear how plant-associated microbiome assembles in plant evolutionary process. In this paper,the ecological adaptation and the evolutionary mechanism of plant-microbiome interactions are summarized based on the evolutionary trajectory of plant phylogeny,plant-microbiome in crop domestication,and the microbe-microbe interaction and evolution under host constraints. Understanding the evolutionary drivers of plant-microbiome interactions may contribute to restoring the beneficial connections between plants and microbes,thus achieving the goals of high yield and high efficiency by increasing crop nutrient absorption,yield and quality. Strengthening the strategy of combining molecular biology and crop genomics will be the key to regulate plant microbiome to promote agricultural sustainability. Meanwhile,the outlook of eco-evolutionary of plant-microbiome interactions is highlighted.
