Other claims from this paper (8)
- Intervention effect Mutation of the chi54 locus eliminated chitinase production in Chromobacterium sp. strain C61.
- Intervention effect Adding chitin to the culture medium increased extracellular enzyme production and chi54 transcript expression in the wild-type strain.
- Intervention effect In planta biocontrol activity of filtrates from cultures grown with chitin was lower than that of filtrates grown without chitin.
- Observation Analysis of C61 culture filtrates revealed an antifungal cyclic lipopeptide, chromobactomycin, whose structure contained a unique nonameric peptide ring.
- Intervention effect Purified chromobactomycin inhibited the growth of several phytopathogenic fungi in vitro.
- Intervention effect Plant application significantly reduced disease severity for several pathogens.
- Intervention effect Chromobactomycin production was reduced in cultures amended with chitin.
- Mechanism The authors suggest that production of both extracellular chitinase Chi54 and chromobactomycin can contribute, in an interconnected way, to suppression of plant disease by strain C61.
