Recent research advances and application potential in agriculture of Pseudomonas chlororaphis

Abstract:

Pseudomonas chlororaphis is one group of the most studied biocontrol strains. Since the beginning of the 19th century, it was firstly isolated and identified as Pseudomonas by Miguela, and then it was reclassified as P. chlororaphis by Peix in 2007. At present, four subspecies affiliated to this species have been reported, which can produce colored phenazine antibiotics. Most of the strains were isolated from the rhizosphere of plants, which play a protective role in plants against the infection of pathogens and nematodes. In this paper, based on the genomic and functional analysis of a new obtained Pseudomonas chlororaphis strain by our group and related literatures, we systematically summarized the taxonomic characteristics, genomic characteristics, functions of metabolites, and application prospects of Pseudomonas chlororaphis. This review will provide reference for the discovery of active metabolites, gene function research and agricultural application of Pseudomonas chlororaphis strains in the future.
