摘　　要：Beneficial root-microbiome interactions offer enormous potential to improve crop performance and stress tolerance.Domestication and improvement reduced the genetic diversity of crops and reshaped their phenotypic traits and their associated microbiome structure and function.However,understanding of the genetic and physiological mechanisms how domestication and improvement modulated root function,microbiome assembly and even coselective patterns remains largely elusive.This review summarizes the current status of how crop domestication and improvement(heterosis)affected root characteristics and their associated microbiome structure and function.Also,it assesses potential mechanisms how crop domestication and improvement reshaped root-microbiome association through gene regulation,root structure and function and root exudate features.A hypothetical strategy is proposed that entangles crop genetics and abiotic interactions with beneficial microbiomes to mitigate the effects of global climate change on crop performance.A comprehensive understanding of the role of crop domestication and improvement in root-associated microbiome interaction will advance future breeding efforts and agricultural management.
