Microbes play a vital role in ecosystem stability. Here, microbes-Acacia association is discussed with particular reference to Arbuscular Mycorrhizal Fungi (AMF) which help in the establishment of crop-plants, especially in arid and semi-arid areas. The association helps to restore the structural composition of soil from the hazardous impact of agrochemicals, increase resistance against various pathogenic attack as well as several abiotic stresses. Further, a comparative account of microbes found in the rhizosphere of Acacia is illustrated. Among these, Rhizobia, Acetobacter, Bradyrhizobium, Bacillus, Pseudomonas and Trichoderma were described in detail. All these microbes can be regarded as Plant Growth Promoting Rhizospheric Microbes (PGPM), some of PGPM are Phosphate Solubilizing Microbe (PSM). Both of them help AMF for infecting mycorrhizal hyphae inside the plant cell. Overall, microbes can be used as biofertilizers along with other organic compounds, that can compensate for the nutrient's availability.
微生物在生态系统稳定性中起着至关重要的作用。在这里,我们将特别讨论微生物-金合欢共生体,特别是丛枝菌根真菌(AMF),它们有助于作物的建立,特别是在干旱和半干旱地区。这种共生关系有助于从农用化学品的有害影响中恢复土壤的结构组成,提高对各种病原攻击以及多种非生物胁迫的抵抗力。此外,还对金合欢根际中发现的微生物进行了比较说明。其中,根瘤菌、醋杆菌、慢生根瘤菌、芽孢杆菌、假单胞菌和木霉被详细描述。所有这些微生物都可以被视为植物促生根际微生物(PGPM),其中一些 PGPM 是解磷微生物(PSM)。它们都有助于 AMF 感染植物细胞内的菌根菌丝。总的来说,微生物可以与其他有机化合物一起用作生物肥料,以弥补养分的可用性。
