Genetic diversification of tomato and agricultural soil management shaped the rhizospheric microbiome of tomato (Solanum lycopersicum)

This study aims to determine whether the genetic diversification associated with tomato domestication and the transition from native to agricultural soils have reduced the taxonomic and functional diversity of the microbial community in the rhizosphere of tomato relatives, including the wild tomato Solanum chilense, a Cherry tomato (intermediate stage of domestication, S. lycopersicum L. var. cerasiforme), and two domesticated tomato types (S. lycopersicum L. var. lycopersicum), the landrace cv. Poncho Negro and the modern cultivar Cal-Ace. Our work identified taxonomic and functional changes involved in the tomato genetic diversification process and demonstrated their relevance to plant fitness.
