作物驯化对根际微生物组的选择

A discussion on issues related to the recruit of rhizosphere microbes caused by crop domestication

作物驯化是人类活动影响下的生物进化过程,不仅会引起作物生理生态以及微生物群落结构和多样性的改变,还对根际微生物的相互关系、功能特征以及作物调控等方面产生影响。同时,根际微生物生态变化也体现了作物在驯化过程中对环境的适应力。本文综述了作物驯化与根际微生物组间的研究进展,讨论了作物驯化可能对根际微生物组的选择及其驱动要素,为改善根际微生物的生态特征及功能,寻找潜在的特殊的微生物资源,提高作物的抗性及养分吸收及实现土壤可持续发展奠定理论基础。

Crop domestication is an evolutionary process manipulated by human acitivities.It not only changes the eco-physiological aspects of crops,microbial community structure and diversity,but also affects the relationship between bacterial and fungal communities in rhizosphere,microbial functional characteristics and crop regulation;while the change of rhizosphere microbial ecology reflects the adaptability of crops to environment.In this review,we summarized the current progress concerning the effect of crop domestication on rhizomicrobiome,as well as the driving factors for rhizosphere microbial selection strategies,which would provide a theoretical foundation for improving the ecological characteristics and functions of rhizosphere microorganisms,searching for potential special microbial resources,increasing crop resistance and nutrient absorption and achieving sustainable development of soil management in the end.
