Project description:The genus Collimonas consists of soil bacteria that are well known for their antifungal activity and for mycophagy, i.e. the ability to grow at the expense of living fungi. The aim of the current study was to gain a better understanding of the mechanisms of antagonism of Collimonas bacteria towards fungi, the involvement of the mycophagous phenotype, and the role of the fungus as a responsive partner in the interaction. In order to reach this aim, the bacterium Collimonas fungivorans and the fungus Aspergillus niger were confronted in vitro. Bacterial and fungal RNA were isolated at two time points during the interaction and analyzed by microarray analysis. Objective: Investigate the expression profile of a bacterium when it was challenged by the presence of an antagonist fungus (control was the expression profile of the bacterium when it was alone). In parallel investigate the expression profile of the antagonist fungus when it was challenged by the presence of the bacterium (control was the expression profile of the fungus when it was alone).(Additional file available in additional.zip)

Project description:Collimonas is a genus of soil bacteria which comprises three recognized species: C. fungivorans, C. pratensis and C. arenae. The bacteria belonging to this genus share the ability to lyse chitin (chitinolysis) and feed on living fungal hyphae (mycophagy), but they differ in colony morphology, physiological properties and antifungal activity. In order to gain a better insight into the genetic background underlying this phenotypic variability of collimonads, we investigated the variability in the genomic content of five strains representing the three formally recognized Collimonas species. The genomic content of four test strains was hybridized on an array representing the reference strain C. fungivorans Ter331.
