Alterations of plants-microbe interactions under environmental stress conditions

The symbiosis of plants with growth promoting fungi comes at a certain price for the host plant. In this review article, we summarized the current knowledge on how plants cope with symbiotic interactions under environmental stress conditions.


Over thousands of years, plants have evolved in proximity to a plethora of different microbes, which eventually led to the establishment of symbiotic plant-microbe interactions. There are many examples of plant growth promoting bacteria and fungi, and how they enhance plant biomass production, productivity, and stress resilience. However, symbiotic interactions have a mutual character, which means that they come on the expense of sharing resources, including inorganic nutrients and photoassimilates. In the published review article, we asked the question as to whether plants can maintain their mutual interaction with their symbionts under unfavorable environmental conditions, or do they have to limit the degree of interaction by reducing fungus load in the interacting tissues. In addition, we discuss molecular measures by which plants can adjust the interaction strength and how the microbial partner answer under these conditions.
