Résumé anglais
Human-directed selection of desirable traits in crop species has led to the development of highly productive agricultural systems, but has not been without tradeoffs. The unforeseen negative impacts of modern conventional agriculture on the environment are now clear, but other hidden tradeoffs have yet to be fully understood. In particular, it is not well understood how shifts in the cultivation environment and directed selection for aboveground productivity in maize (Zea mays L.) may have impacted belowground traits and rhizosphere interactions. Agricultural intensification has dramatically increased the use of synthetic agrochemicals over inputs of organic matter, but it remains unclear whether this shift has decreased the ability of maize to recruit and benefit from a diverse rhizobiome. Because of the heightened importance of plantmicrobe interactions and microbially mediated processes for nutrient acquisition in organically managed agroecosystems, potential negative impacts would have profound implications for the sustainable production of this nutritionally and economically important crop in the future.
