RANGEL-IBANEZ, DANIELA,  and  ZAFRA, GERMAN,. Microbial diversity associated to Espeletia spp. in high mountain ecosystems. Rev.Bio.Agro [online]. 2022, vol.20, n.2, pp.129-141.  Epub July 01, 2022. ISSN 1692-3561.  https://doi.org/10.18684/rbsaa.v20.n1.2022.1640.

High mountain ecosystems have unique environmental characteristics, provide essential natural resources for the maintenance of life, and represent hotspots of biodiversity and endemism for animal and vegetal species. Within the vast diversity that characterizes high mountain environments, microbial diversity stands out due to its key role in the maintenance of soil stability and sustainability, promoting plant growth through the transformation of complex substances present in the environment into bioavailable forms, exerting biocontrol over phytopathogens or through the secretion of hormones and other compounds that allow better foliar and root development. Microorganisms establish important biological interactions with native plants in high mountains and páramos, including the different species of Espeletia, thus allowing to improve their role as regulators of water sources. Therefore, this review aims to consolidate the current knowledge about the microbial diversity present in high mountain soils, highlighting the microbiota associated with Espeletia spp. and their possible interactions.
