The vegetation in the Arabian Peninsula experiences drought, heat, soil salinity, and low fertility, mainly due to low phosphorus (P) availability. The beneficial mycorrhizal symbiosis between plants and arbuscular mycorrhizal fungi (AMF) is a key factor supporting plant growth under such environmental conditions. Therefore, AMF strains isolated from these soils might be useful as biotechnological tools for agriculture and revegetation practices in the region. Here we present a pioneering program to isolate, identify, and apply AMF isolated from rhizosphere soils of agricultural and natural habitats, namely date palm plantations and five native desert plants, respectively in the Southern Arabian Peninsula. We established taxonomically unique AMF species as single-spore cultures as part of an expanding collection of AMF strains adapted to arid ecosystems. Preliminary experiments were conducted to evaluate the abilities of these AMF strains to promote seedling growth of a main crop L. and a common plant L. (Druce) in the Arabian Peninsula. The results showed that inoculation with certain AMF species enhanced the growth of both plants, highlighting the potential of these fungi as part of sustainable land use practices in this region.
阿拉伯半岛的植被面临干旱、高温、土壤盐碱化和肥力低下等问题，主要原因是可利用的磷（P）含量低。植物与丛枝菌根真菌（AMF）之间有益的菌根共生关系是在这种环境条件下支持植物生长的关键因素。因此，从这些土壤中分离出的AMF菌株可能作为该地区农业和植被恢复实践的生物技术工具。在这里，我们展示了一个开创性的项目，分别从阿拉伯半岛南部农业和自然栖息地（即枣椰种植园和五种本土沙漠植物）的根际土壤中分离、鉴定和应用AMF。作为适应干旱生态系统的AMF菌株不断扩大的收集工作的一部分，我们建立了分类学上独特的AMF物种作为单孢子培养物。进行了初步实验，以评估这些AMF菌株促进阿拉伯半岛主要作物L.和常见植物L.（德鲁斯）幼苗生长的能力。结果表明，接种某些AMF物种可促进这两种植物的生长，突出了这些真菌作为该地区可持续土地利用实践一部分的潜力。
