Phase Variation in Myxococcus xanthus Yields Cells Specialized for Iron Sequestration
Myxococcus xanthus undergoes phase variation during growth to produce predominantly two colony phenotypes. The majority are yellow colonies containing swarm-proficient cells and a minority are tan colonies containing swarm-deficient cells. Comparison of the transcriptomes of a yellow variant, a tan variant, and three tan mutants led to the identification of differentially-regulated genes that d...
متن کاملPhase transitions during fruiting body formation in Myxococcus xanthus
The formation of a collectively moving group benefits individuals within a population in a variety of ways such as ultra-sensitivity to perturbation, collective modes of feeding, and protection from environmental stress. While some collective groups use a single organizing principle, others can dynamically shift the behavior of the group by modifying the interaction rules at the individual leve...
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...
متن کاملMicrocyst germination in Myxococcus xanthus.
Germination of glycerol-prepared microcysts of Myxococcus xanthus was studied. The sequence of morphological events during germination resembled that of germinating fruiting body-microcysts. The turbidity drop of a culture of germinating microcysts could be described by McCormick's formula derived for germinating Bacillus spores. The rate of uptake of labeled glycine and acetate did not change ...
