Phytomicrobiome and Stress Regulation, a volume in the Microbiome Research in Plants and Soil series, provides a comprehensive overview of major abiotic and biotic stresses faced by plants providing key insights into advancements in the use of phytobiomes in stress mitigations of plants. Crop microbes helps plant growth and tolerance to a variety of biotic and abiotic stresses. Studies have reported that the belowground microbial communities act as regional drivers of the aboveground biotic communities. Further, in driving ecological functions, composition and microbial diversity are extensively recognized as key factors. Any change in the composition of microbial communities because of environmental change eventually effects the functioning of the whole ecosystem due to the strong link between microbial communities and soil functioning. Hence, changes in microbial community structure, composition and function are important factors to understand. Phytomicrobiome and Stress Regulation addresses the need for a more complete understanding for the responses and dynamic roles of microbial communities in mitigating various biotic and abiotic stresses particularly for future climate change scenarios. It explores the implications of different stresses and environmental perturbations on variations in structure and function of phytobiomes and highlights recent advances in the field of applied crop microbiology.
