Project description:Our ChipSeq analysis show that while FrzCD does not bind DNA specific regions, ParB binds parS consistent with what as been previously shown. The FrzCD chemoreceptor from the gliding bacterium Myxococcus xanthus forms cytoplasmic clusters that occupy a large central region of the cell body also occupied by the nucleoid. FrzCD directly binds to the nucleoid and the FrzCD binding to the DNA leads to the formation of chemosensory complexes. This supra-molecular organization is required for cooperative interactions between clustered receptors, in turn important for the modulation of bacterial social behaviors.

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.

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 regulation of gene expression during growth and development, transcription start sites were identified using Cappable-seq. To this end, 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.

Project description:In response to starvation, Myxococcus xanthus initiates a developmental program that results in the formation of spore-filled multicellular fruiting bodies. Here we have used cDNA microarray analysis to determine changes in the global gene expression at different time points of the developmental process. The expression of nearly 900 genes was found to be altered at least two-fold during development as compared to vegetative cells. Genes encoding proteins with typical vegetative functions such as protein synthesis and energy metabolism were transcriptionally down-regulated in the early stages of development. Among the 430 genes transcriptionally up-regulated during development genes with regulatory functions were overrepresented; underlining that fruiting body formation relies on a complex signalling network. Notably, almost 40% of all genes with increased expression at different stages of development encoded hypothetical proteins indicating a large unexplored potential of proteins important for fruiting body formation.
