Vegetative Cells and Microcysts of Myxococcus xanthus
A number of reports have demonstrated that microcysts, the resting cells produced by most myxobacteria, are more resistant than the corresponding vegetative cells. Baur (1) showed that mycrocysts of Myxococcus ruber withstood desiccation and wet and dry heat better than did vegetative cells. In 1936, Imshenetsky and Solnetzewa (6) reported comparable findings for Cytophaga hutchinsonil and C. e...
متن کاملPredataxis behavior in Myxococcus xanthus.
Spatial organization of cells is important for both multicellular development and tactic responses to a changing environment. We find that the social bacterium, Myxococcus xanthus utilizes a chemotaxis (Che)-like pathway to regulate multicellular rippling during predation of other microbial species. Tracking of GFP-labeled cells indicates directed movement of M. xanthus cells during the formati...
متن کاملGlycerol 3-phosphate inhibits swarming and aggregation of Myxococcus xanthus.
We have cloned a gene of Myxococcus xanthus with similarities to the permease for glycerol 3-phosphate (G3P) of other bacteria. Expression of the gene increased significantly during the first hours of starvation. Swarming of the wild-type strain was inhibited and aggregation was delayed by G3P. Conversely, a DeltaglpT strain aggregated even on rich medium. These results indicate that G3P may fu...
متن کاملType IV pilus of Myxococcus xanthus is a motility apparatus controlled by the frz chemosensory system
Although flagella are the best-understood means of locomotion in bacteria [1], other bacterial motility mechanisms must exist as many diverse groups of bacteria move without the aid of flagella [2-4]. One unusual structure that may contribute to motility is the type IV pilus [5,6]. Genetic evidence indicates that type IV pili are required for social gliding motility (S-motility) in Myxococcus, ...
متن کاملQuantifying aggregation dynamics during Myxococcus xanthus development.
Under starvation conditions, a swarm of Myxococcus xanthus cells will undergo development, a multicellular process culminating in the formation of many aggregates called fruiting bodies, each of which contains up to 100,000 spores. The mechanics of symmetry breaking and the self-organization of cells into fruiting bodies is an active area of research. Here we use microcinematography and automat...
