Changes of Arbuscular Mycorrhizal Fungal Community and Glomalin in the Rhizosphere along the Distribution Gradient of Zonal Stipa Populations across the Arid and Semiarid Steppe

Abstract

This study fills a gap in our understanding of the soil arbuscular mycorrhizal fungal community distribution, community composition changes, and diversity of Stipa species along different Stipa population substitution distributions and of their adaptive relationships; furthermore, the differences in the glomalin-related soil protein (GRSP) contents in the rhizospheres of different Stipa species and GRSP’s contribution to the grassland organic carbon pool were investigated. These findings provide a theoretical basis for the protection and utilization of regional biodiversity resources and sustainable ecosystem development.

Diversity, Distribution, and applications of arbuscular mycorrhizal fungi in the Arabian Peninsula

“…Similarly, AMF is involved in the solubilization of potassium (K) as it is trapped in a crystal lattice and only 0.1 to 2 % is available for the plant uptake. AMF releases organic acids like p-coumaric acid, p-hydroxybenzoic acid, and caffeic acid which helps to solubilize K and make it available for plant’s uptake ( Ma et al, 2022b , Priyadharsini and Muthukumar, 2016 ).…”

Spatial distribution and drivers of arbuscular mycorrhizal fungi on the Tibetan Plateau

“…However, consistent conclusions regarding AMF biogeographic patterns and their controlling factors have yet to be reached ( Xiang et al., 2014 ; Davison et al., 2015 ). Some studies emphasize edaphic factors and climate parameters in explaining the variance in AMF distribution patterns ( Ma et al., 2022 ; Ma et al., 2023a ; Ma et al., 2023b )—for instance, soil texture and fertility are identified as key drivers determining the AMF community structure ( Goldmann et al., 2020 ; Aker et al., 2022 ; Zhang et al., 2022 ; Liu et al., 2023 ).…”
