Predataxis 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 کاملThe Mechanistic Basis of Myxococcus xanthus Rippling Behavior and Its Physiological Role during Predation
Myxococcus xanthus cells self-organize into periodic bands of traveling waves, termed ripples, during multicellular fruiting body development and predation on other bacteria. To investigate the mechanistic basis of rippling behavior and its physiological role during predation by this Gram-negative soil bacterium, we have used an approach that combines mathematical modeling with experimental obs...
متن کاملMyxobacteria motility: a novel 3D model of rippling behaviour in Myxococcus xanthus
Bacterial populations provide interesting examples of how relatively simple signalling mechanisms can result in complex behaviour of the colony. A well studied example of this phenomenon can be found in myxobacteria; cells can coordinate themselves to form intricate rippling patterns and fruiting bodies using localised signalling. Our work attempts to understand and model this emergent behaviou...
متن کاملLipolytic enzymes in Myxococcus xanthus.
The genome of Myxococcus xanthus encodes lipolytic enzymes in three different families: patatin lipases, alpha/beta hydrolases, and GDSL lipases. One member of each family was characterized. The protein encoded by MXAN_3852 contains motifs characteristic of patatins. MXAN_5522 encodes a protein with the G-X-S-X-G motif characteristic of the lipase subfamily of alpha/beta hydrolases. MXAN_4569 e...
متن کاملAccordion waves in Myxococcus xanthus.
Myxococcus xanthus are Gram-negative bacteria that glide on solid surfaces, periodically reversing their direction of movement. When starved, M. xanthus cells organize their movements into waves of cell density that sweep over the colony surface. These waves are unique: Although they appear to interpenetrate, they actually reflect off one another when they collide, so that each wave crest oscil...
