Gerayeli N. & Baghaee-Ravari S. 2016. The biological role of bacteriocins of gram-negative bacteria. Plant Pathology Science 5(2): 63-70.
Bacteriocins are a kind of antimicrobial peptides or proteins, produced by some gram-negative bacteria, for competition for space and resources, which can kill or inhibit closely-related bacteria. The producer bacterium is immune to these material by specific immunity proteins. Bacteriocins vary in size, microbial targets, mode of action and immunity mechanism. So far lots of bacteriocins that produced by specific isolates of gram-negative bacteria have been identified, which often have a high molecular weight. In this paper, mode of production, and mechanisms of action of bacteriocins, and their role in management of plants bacterial diseases, described.
