An Overview of Metabolic Activity, Beneficial and Pathogenic Aspects of Spp.

is an important bacterial species which has different beneficial effects, such as promoting the plant growth, including rhizosphere competence for the secretion of allelochemicals, production of antibiotics, and siderophores. In addition, most of species have demonstrated promising biocontrol action against different phytopathogens for diverse crops. In particular, demonstrates significant biotechnological potential as a source of novel antibiotics and bioactive secondary metabolites. The current review is concerned with spp. covering the following aspects: discovering, classification, distribution, plant growth promoting effect, and antimicrobial activity of different species of , shedding light on the most important secondary metabolites, their pathogenic effects, and biochemical characterization of some important species of such as , , , , , and .
