驯化对谷子-根际微生物互作机制影响的进展与展望

Impact of domestication on the mechanism of millet and rhizosphere microorganism interactions

  • 摘要: 根际微生物可赋予植物新的抗逆性, 其群落结构及生态功能的变化也体现了作物对环境变化的适应能力。驯化影响作物的遗传多样性、生理性状及其代谢产物, 进而会对根际微生物群落组成与功能产生作用。目前, 对于作物驯化的研究多关注植物遗传多样性与植物表型和生理特性之间的相互关联及影响机制, 微生物在作物驯化过程中的作用及其与植物互作机制的探索还处于起步阶段。为此, 本文首先对驯化过程在禾本科作物根际微生物群落构建中的作用进行了回顾, 针对起源于中国的重要旱作C4模式作物谷子, 系统总结了谷子的驯化过程及其对谷子生长、生理性状和根际微生物的影响, 以及驯化对谷子根际微生物间互作和谷子与微生物互作的作用机制, 以期为恢复农田生态系统中的作物-微生物有益关系提供科学依据。

     

    Abstract: Rhizosphere microorganisms endow plants with stress resistance, and variations in their community structure and ecological functions reflect the adaptability of crops to environmental changes. Domestication affects the genetic diversity, physiological traits, and crop metabolites, affecting the composition and function of rhizosphere microbial communities. To date, studies on crop domestication have mainly focused on the correlation and influencing mechanisms between plant genetic diversity and plant phenotypic and physiological characteristics. However, the role of microorganisms in crop domestication and exploration of interactive mechanisms with plants are still in their infancy. In this review, we systematically summarize the current progress regarding the effects of domestication on the community construction of gramineous crop rhizosphere microorganisms. Therefore, we focused on foxtail millet, an important C4 model plant originating in China, to discuss the effects of domestication on foxtail millet growth and physiological traits and how these changes may further affect the structural and functional properties of rhizosphere microbial communities. This review provides theoretical guidance for the restoration of beneficial crop-microbe relationships in agricultural ecosystems.
