Response of microorganisms to climate change:
Altered environmental conditions due to climate change are likely to induce changes in plant physiology and rootexudation. Elevated CO2 in particular will, in many cases, lead to increased C allocation to the root zone and potentially also lead to altered composition of root exudates. Elevated temperature and drought might induce similar changes, and together they are likely to lead to changes in the composition, abundance or activity of plant associated microbial communities. Climate change may thus substantially impact the diversity and activities of such plant associated microbial communities. Consequently, microorganisms known for their beneficial effects on plant growth or health might also be impaired, in terms of exhibiting their desirable properties, secretion of quorum sensing molecules and their colonization capacity under certain conditions. However, a detailed understanding on how exactly plant-associated microbial communities are influenced either directly by altered environmental conditions or indirectly by altered plant physiology and how this affects plant performance and finally ecosystem functioning is what we are trying to understand through the FACE and TGT experiments .
