Many halophytes are considered to be salt hyperaccumulators, adopting ion extrusion and inclusion mechanisms. Such plants, with high aboveground biomass, may play crucial roles in saline habitats, including soil desalination and phytoremediation of polluted soils and waters. These plants cause significant changes in some of the soil's physical and chemical properties; and have proven efficient in removing heavy metals and metabolizing organic compounds from oil and gas activities. Halophytes in Qatar, such as , , , and , are shown here to play significant roles in the phytoremediation of polluted soils and waters. Microorganisms associated with these halophytes (such as endophytic bacteria) might boost these plants to remediate saline and polluted soils. A significant number of these bacteria, such as spp. and spp., are reported here to play important roles in many sectors of life. We explore the mechanisms adopted by the endophytic bacteria to promote and support these halophytes in the desalination of saline soils and phytoremediation of polluted soils. The possible roles played by endophytes in different parts of native plants are given to elucidate the mechanisms of cooperation between these native plants and the associated microorganisms.
许多盐生植物被认为是盐超积累植物，采用离子外排和离子包容机制。这类地上生物量高的植物可能在盐碱生境中发挥关键作用，包括土壤脱盐以及对污染土壤和水体的植物修复。这些植物会引起土壤一些物理和化学性质的显著变化；并且已证明在去除重金属以及代谢来自石油和天然气活动的有机化合物方面很有效。卡塔尔的盐生植物，如 、 、 和 ，在此显示出在污染土壤和水体的植物修复中发挥着重要作用。与这些盐生植物相关的微生物（如内生细菌）可能会促进这些植物对盐碱和污染土壤的修复。据报道，大量这类细菌，如 属和 属的细菌，在许多生命领域中发挥着重要作用。我们探究内生细菌在盐碱土壤脱盐和污染土壤植物修复过程中促进和支持这些盐生植物所采用的机制。给出了内生菌在本地植物不同部位可能发挥的作用，以阐明这些本地植物与相关微生物之间的合作机制。
