Tolerance to increased environmental temperature in pine plants inoculated with edible ectomycorrhizal fungi and beneficial bacteria

Abstract

Global warming is generating drastic changes in the planet's ecosystems, causing the loss of biodiversity and the modification of its natural distribution. Massive deforestations and the lack of successful reforestations have aggravated this global problem. It has been shown that in general natural ecosystems and in particular forest ecosystems are very sensitive to increases in temperature. Mexico is one of the main diversification centers of the Pinus genus, whose species are the main suppliers of wood production in the country. For this reason, currently various species of pine have been used in national reforestation programs, which have frequently failed due to the absence of the incorporation of ectomycorrhiza, which is an obligatory symbiosis for the development of said forest species. Additionally, in despite the challenging scenario of global warming, to date studies linked to the tolerance that ectomycorrhiza can confer to increased temperatures have been scarce globally.
