In order to kill competing strains of the same or closely related bacterial species, many bacteria produce potent narrow-spectrum protein antibiotics known as bacteriocins. Two sequenced strains of the phytopathogenic bacterium Pectobacterium carotovorum carry genes encoding putative bacteriocins which have seemingly evolved through a recombination event to encode proteins containing an N-termi...

In Morocco, Pectobacterium carotovorum is well known as causal agents of potato soft rot. Actually, there are no efficient bactericides used to protect potato against Pectobacterium spp. biological control using antagonistic could be an interesting approach to manage this disease. Thus, a collection of thirty antagonists isolated from compost, rhizospheres and endophytes of various crop plants ...
