Metagenomic analyses of bacterial diversity from rhizosphere soils of 27 different tomato varieties along a domestication gradient

This study evaluates whether variation in plant traits along a domestication gradient determines the composition and functionality of soil microbiomes; and whether changes in microbial composition are related with targeted traits (e.g., fruit traits) or are side effects of less-often-targeted traits (e.g., resistance) during crop breeding.本研究旨在探究沿驯化梯度分布的植物性状变异是否决定土壤微生物组的组成与功能；同时解析作物育种过程中，微生物组组成的变化究竟与目标性状（例如果实性状）相关，还是由较少作为选育目标的性状（如抗逆性）所产生的附带效应。
