Stressor (biotic as well as abiotic) generally hijack the plant growth and yield characters in hostile environment leading to poor germination of the plants and yield. Among the plant growth promoting rhizobacteria, spp. (Gram-negative prokaryote) are considered to improve the plant health. Various mechanisms are implicated behind improved plant health in spp. inoculated plants. For example, acceleration of phytohormone like Indole-3-Acetic Acid production, obviation of various stressors, nitrogen fixation, pesticides and oil globules degradation, heavy metals metabolization, etc. are the key characteristics of spp. action. In addition, application of this bacteria has also become helpful in the reclamation of soil suggesting to be a putative agent which can be used in the transformation of virgin land to fertile one. Application of pesticides of chemical origin are being put on suspension mode as the related awareness program is still on. As far as the limitations of this microbe is concerned, commercial level formulations availability is still a great menace. Present review has been aimed to appraise the researchers pertaining to utility of spp. in the amelioration of plant health in sustainable agroecosystem. The article has been written with the target to gather maximum information into single pot so that it could reach to the dedicated researchers.
胁迫因素（生物和非生物的）通常会在恶劣环境中影响植物的生长和产量特征，导致植物发芽率低和产量下降。在促进植物生长的根际细菌中，[具体菌属]（革兰氏阴性原核生物）被认为可以改善植物健康状况。接种了[具体菌属]的植物，其健康状况改善背后涉及多种机制。例如，加速吲哚 - 3 - 乙酸等植物激素的产生、消除各种胁迫因素、固氮、农药和油滴降解、重金属代谢等都是[具体菌属]作用的关键特征。此外，这种细菌的应用在土壤改良方面也很有帮助，表明它是一种可以用于将荒地转化为肥沃土地的假定试剂。由于相关的宣传项目仍在进行，化学合成农药的使用正处于暂停状态。就这种微生物的局限性而言，商业级制剂的可得性仍然是一个很大的问题。本综述旨在向研究人员评估[具体菌属]在可持续农业生态系统中改善植物健康方面的效用。撰写本文的目的是将尽可能多的信息汇总到一起，以便能够传达给专业研究人员。
