摘      要：Soil-derived microbiota associated with plant roots are conducive to plant growth and stress ***,the spatio-temporal dynamics of microbiota in response to organochlorine pollution during the unstable vegetative growth phase of rice is not well *** this study,we focused on the rice(Oryza sativa L.)microbiota across the bulk soil,rhizosphere and endosphere compartments during the vegetative growth phase in two different soils with and without lindane *** results showed that the factors of growth time,soil types and rhizo-compartments had significant influence on the microbial communities of rice,while lindane mostly stimulated the construction of endosphere microbiota at the vegetative *** rice root-soil-microbe interactions induced an inhibition effect on lindane removal at the later vegetative growth phase in rice-growth-dependent anaerobic condition,likely due to the root oxygen loss and microbial mediated co-occurring competitive electron-consuming redox processes in *** rhizocompartment owned distinct microbial communities,and therefore,presented specific ecologically functional categories,while the moderate functional differences were also affected by plants species and residual pollution *** work revealed the underground micro-ecological process of microbiota and especially their potential linkage to the natural attenuation of residual organochlorine such as lindane.
