Abstract

Anthropogenic activities in the last century have highly impacted our physical environment in many different ways. Burning of fossil fuels, pollution, deforestation, and production of pesticides and fertilizers have elicited climate change (global warming) and have inadvertently disturbed the ecosystem balance. Arbuscular mycorrhizal fungi (AMF) which are widely distributed in terrestrial ecosystems form a mutualistic interaction known as arbuscular mycorrhiza(AM) with the roots of most land plants. Their contribution to ecosystem functioning by regulating plant function, nutrient uptake, stress resistance, and community interactions is noteworthy. Different studies have suggested that an increase in temperature, carbon dioxide enrichment, and increased nutrient deposition in the ecosystem which is the result of imprudent human activities strongly impact the colonization, diversity, and function of AMF in the terrestrial ecosystems. This review briefly describes the responses of AMF to different climatic factors and their consequences on host plant functioning and productivity. Understanding the dynamics of plant-fungal associations in the context of global climate change will help in designing strategies to alleviate detrimental anthropogenic impacts to protect AMF diversity and consequently ecosystem functioning and its sustainability.
