“…These results indicate that AM fungi enhance growth and stress tolerance in rice under aerobic conditions which is accompanied by intermittent drying periods that can be harmful for the growth of rice plants. A significant correlation between K and P during AM symbiosis has been reported by Olsson et al, (2011); results obtained in our study upholds this correlation since rice plants inoculated with AMF displayed significantly higher P and K content as compared to the uninoculated rice plants. Gao et al, (2007) studied the effect of AMF inoculation on growth performance and Zn uptake by rice genotypes varying in Zn uptake when non mycorrhizal and showed that AMF inoculated plants produced more biomass and took up more Zn than non-mycorrhizal controls.…”

“…Rhizophagus intraradices-inoculated plants generally exhibited nutrient ratios indicative of P limitation, whereas for G. margarita-mycorrhized plants, corresponding ratios strongly implied either N or K limitation (Veresoglou et al 2011). Particleinduced X-ray emission experiments involving the AMF R. intraradices suggest that the K taken up by AMF were accumulated in various fungal structures like hyphae, vesicles, and spores (Johansson and Campbell 1988;Pallon et al 2007;Olsson et al 2008Olsson et al , 2011. Although transporters and channels of AMF involved in P transport are characterized, these are missing for K (Garcia and Zimmermann 2014).…”

Microbial interaction is a key determinant of soil fertility, plant health, and crop productivity. Arbuscular mycorrhizal fungi (AMF) belonging to the phylum Glomeromycota are a ubiquitous component of most natural and agroecosystems. These fungi associate with most of the plant species and provide several benefits including better nutrition and increased tolerance to various biotic and abiotic stresses. Mycorrhizal symbiosis can affect the microbial population and their activity in the rhizosphere both qualitatively and quantitatively including mineral solubilization by microorganisms. These changes are mediated through the so-called mycorrhizosphere effect resulting from direct or indirect changes in root exudation (composition and quantity) patterns or through fungal exudates. In most instances, the interaction between AMF and nutrient-solubilizing microorganisms is synergistic resulting in stimulation of plant growth through improved nutrient acquisition and inhibition of plant pathogens. The ecological impact of AMF interactions with microorganisms involved in potassium solubilization is not well resolved compared to those involved in phosphate solubilization. Although direct studies on the interactions between AMF and potassium-solubilizing microorganisms (KSMs) on plant growth are limited, studies on plant growth-promoting microorganisms (PGPMs) and AMF do involve organisms with K-solubilizing capabilities. Evidence does exist on the influence of KSMs on mycorrhizal formation and function. Interactions between AMF and KSMs are vital in sustainable low-input crop production systems that rely on biological processes to achieve improved plant growth and yield in addition to maintaining soil fertility. This article examines the interactions between AMF and KSMs on plant growth, development, and crop productivity.

“…Interestingly, a strong correlation observed between the distribution of P and K + during ECM and AM symbiosis has been reported (Smith et al 1981;Cumming 1993;Wallander and Pallon 2005;Olsson et al 2011). Moreover, K + and P have been found in the same fungal compartments in Paxillus involutus (Orlovich and Ashford 1993;Ashford et al 1999) and Scleroderma verrucosum (Jung and Tamai 2013), such as vacuoles.…”

“…The effect of AM symbiosis on the K + nutrition of plants was found using appropriate techniques. Assessment of the K + distribution in AM fungi (Rhizophagus irregularis) through particle-induced X-ray emission (PIXE) experiments (Johansson and Campbell 1988) showed high K + accumulation in spores (Pallon et al 2007), vesicles (Olsson et al 2011), and hyphae (Olsson et al 2008).…”

Mycorrhizae have been key living microorganisms in the plant colonization of terrestrial environments. The crucial roles of mycorrhizae are to provide plant nutrition and stress resistance for plant growth and development. Potassium (K + ) shows important functions in different metabolic processes and physiological functions and is the third crucial component of most crop fertilizers (after nitrogen and phosphorus). This chapter discusses the current state of knowledge about the role of mycorrhizal symbiosis in the release, solubilization, and transport of potassium from the soil to plants. Improved metagenomic analyses and the availability of transcriptome data provide promising tools for studying fungal weathering and the mycorrhizal contributions to K + solubilization and K + transport to plants. Additionally, some benefits of mycorrhizal potassium uptake in plants are described.
