Impact of Climate Change on Plant–Microbe Interactions under Agroecosystems. Climate Change and Agricultural Ecosystems, 2019, Pages: 153 - 179.

      Anthropogenic climate change is of prime global concern and directly or indirectly affects the plant and microbial diversity of planet Earth. It is evident that anticipated increase in CO2, temperature, and altered precipitation are major consequences of climate change that has added the complexity and uncertainty to the plants and agroecosystem and threaten their sustainable management. Plant–microbe interactions are an important factor that influence the response of plants to alterations in climatic conditions. However, there are some beneficial plant-associated rhizobacteria and mycorrhiza that play an important role in reducing the ill-effects of climate change, such as drought, salinity, and plant diseases, etc. Apparently, it has been determined that climate change indirectly influences crop quality and plant–microbe relationships through the anthropogenic introduction of xenobiotics (pesticides, polycyclic aromatic hydrocarbons, etc.,) in terrestrial environments, posing risks to soil health by disturbing soil microbial enzyme activities and community structures. Considering the long-term effects of global climate change, it is essential to review the impacts of climate change on various life form sustaining components including soil–plant–microbe relationships with special reference to the belowground environment. This chapter could also help in predicting how plant–microbe interactions respond to climate change as well as the selection of suitable crops that would be able to produce more yields even under multistress conditions.

Keywords: Climate change, elevated CO2 plant–microbe interactions, biocontrol host–pathogen interactions, xenobiotics.

      In the past four decades, tremendous progress has been made in understanding how plants respond to microbial colonization and how microbial pathogens and symbionts reprogram plant cellular processes. In contrast, our knowledge of how environmental conditions impact plant-microbe interactions is less understood at the mechanistic level, as most molecular studies are performed under simple and static laboratory conditions. In this review, we highlight research that begins to shed light on the mechanisms by which environmental conditions influence diverse plant-pathogen, plant-symbiont, and plant-microbiota interactions. There is a great need to increase efforts in this important area of research in order to reach a systems-level understanding of plant-microbe interactions that are more reflective of what occurs in nature.

Keywords: plant pathogen, symbiosis, abiotic stress, temperature, light, circadian clock, humidity, nutrient, innate immunity, climate change.
