Developmental expression of dnaA is required for sporulation and timing of fruiting body formation in Myxococcus xanthus.
Inhibition of DNA replication within the first 6 h of development results in a block in the developmental programme in the social soil bacterium Myxococcus xanthus. We have interpreted these data to imply that M. xanthus requires a new round of DNA replication early in the developmental programme. To further understand the role of DNA replication during development in M. xanthus we focused on t...
متن کاملThe response regulator PhoP4 is required for late developmental events in Myxococcus xanthus.
Phosphate regulation is complex in the developmental prokaryote Myxococcus xanthus, and requires at least four two-component systems (TCSs). Here, the identification and characterization of a member of one TCS, designated PhoP4, is reported. phoP4 insertion and in-frame deletion strains caused spore viability to be decreased by nearly two orders of magnitude, and reduced all three development-s...
متن کاملThe enhancer binding protein Nla6 regulates developmental genes that are important for Myxococcus xanthus sporulation.
UNLABELLED In the bacterium Myxococcus xanthus, starvation triggers the formation of multicellular fruiting bodies containing thousands of stress-resistant spores. Recent work showed that fruiting body development is regulated by a cascade of transcriptional activators called enhancer binding proteins (EBPs). The EBP Nla6 is a key component of this cascade; it regulates the promoters of other E...
متن کاملRasA is required for Myxococcus xanthus development and social motility.
An insertion in the rasA gene entirely blocked developmental aggregation and sporulation in Myxococcus xanthus while also reducing swarm expansion on a 0.3% agar surface. Data presented here demonstrate that rasA is required for extracellular fibril formation and social gliding motility.
متن کاملSporulation of Myxococcus xanthus in liquid shake flask cultures.
When suspended in a liquid starvation medium, exponentially growing Myxococcus xanthus sporulated within 3 days. These myxospores were similar to spores developed within fruiting bodies, as determined by electron microscopy and the production of spore-specific protein S. This liquid sporulation system may be useful as a means of preparing large quantities of myxospores and extracellular fluid f...
