Genetic components of Escherichia coli involved in its complex preypredator interaction with Myxococcus xanthus

Project description:Myxococcus xanthus and Escherichia coli represent a well-studied microbial predatorprey pair frequently examined in laboratory settings. While significant progress has been made in comprehending the mechanisms governing M. xanthus predation, various aspects of the response and defensive mechanisms of E. coli as prey remain elusive. In this study, the E. coli large-scale chromosome deletion library was screened, and a mutant designated as ME5012 was identified to possess remarkable resistance to predation by M. xanthus. Within the deleted region of ME5012 encompassing seven genes, the significance of dusB and fis genes in driving the observed resistant phenotype became apparent. Specifically, the deletion of fis resulted in a notable reduction in flagellum production in E. coli, contributing to a certain level of resistance against predation by M. xanthus. Meanwhile, the removal of dusB in E. coli led to diminished inducibility of myxovirescin A production by M. xanthus, accompanied by a slight increase in resistance to myxovirescin A. These findings shed light on the molecular mechanisms underlying the complex interaction between M. xanthus and E. coli in a predatory context.

Bdellovibrio bacteriovorus attack phase and Host-Independent grown cells

Project description:Bdellovibrio is a Gram-negative bacterium that preys upon other Gram-negative bacteria, including many pathogens, and as such has potential as a biocontrol agent. Little is known of the molecular and genetic control of Bdellovibrio’s attack upon its prey and of the nature of the HI phenotype. Here, we apply microarray technology to monitor changes of gene expression during the initial stages of prey infection to determine which predatory genes are important in this stage and to gain insight into possible regulatory mechanisms controlling the predation process. Comparison to gene expression during HI growth reveals a “predatosome” of genes specifically upregulated during predation and implicates some of those important in HI growth.

Deciphering the regulon of the alternative extracytoplasmic function (ECF) sigma factor DvdS and its dependence on the regulatory proteins CarD and CarG

Project description:This study addresses the key role of the extracytoplasmic function (ECF) sigma factor DdvS in the Gram-negative bacterium Myxococcus xanthus. It allows us to determine its regulon and it shows that the expression of ddvS and its regulón depends on the global regulatory complex CarD-CarG.

RNA-seq analysis of Myxococcus xanthus at various developmental time points

Project description:Myxococcus xanthus is a model organism for studying social behaviors and cell differentiation in bacteria. Upon nutrient depletion, M. xanthus cells initiate a developmental program that culminates in formation of spore-filled fruiting bodies and peripheral rods outside of fruiting bodies. Completion of this developmental program depends on fine-tuned spatial and temporal regulation of gene expression, intercellular communication, signaling by nucleotide-based second messengers, and motility. In order to understand stage-specific gene expression during growth and development, we extracted total RNA from vegetative cells (referred as 0 h of development) and from cells developed for 6, 12, 18 and 24 h under submerged conditions in two replicates.
