Arbuscular Mycorrhizal Symbiosis Under Stress Conditions: Benefits and Costs

Chapter
Part of the Cellular Origin, Life in Extreme Habitats and Astrobiology book series (COLE, volume 17)

Abstract

Mycorrhization is a highly prevalent association of plants with fungi. Most plant species harbor symbioses with arbuscular mycorrhizal fungi (AMF), which take place within the plant roots. Arbuscular mycorrhizal (AM) symbiosis plays a major role in ecosystems, facilitating nutrient cycling by providing plants with essential nutrients. The AMF are members of the fungal phylum Glomeromycota (Schüssler et al., 2001) and form symbiotic associations with most terrestrial vascular flowering plants (Smith and Read, 1997). In addition to increasing nutrient uptake, other key contributions of AMF to plants have been recorded, including improved rooting and plant establishment, improved vegetative growth, and accelerated budding and flowering (Smith and Read, 1997). Moreover, the plant–AMF symbiosis has been shown to promote the plant’s ability to withstand numerous abiotic stress conditions. This phenomenon is the subject of the present review.
