Pattern formation: fruiting body morphogenesis in Myxococcus xanthus.
When Myxococcus xanthus cells are exposed to starvation, they respond with dramatic behavioral changes. The expansive swarming behavior stops and the cells begin to aggregate into multicellular fruiting bodies. The cell-surface-associated C-signal has been identified as the signal that induces aggregation. Recently, several of the components in the C-signal transduction pathway have been identi...
متن کاملPattern-formation mechanisms in motility mutants of Myxococcus xanthus.
Formation of spatial patterns of cells is a recurring theme in biology and often depends on regulated cell motility. Motility of the rod-shaped cells of the bacterium Myxococcus xanthus depends on two motility machineries, type IV pili (giving rise to S-motility) and the gliding motility apparatus (giving rise to A-motility). Cell motility is regulated by occasional reversals. Moving M. xanthus...
متن کاملPurification and properties of Myxococcus xanthus cell surface antigen 1604.
A cell surface antigen complex from Zwittergent-solubilized Myxococcus xanthus has been purified by immunoaffinity chromatography with monoclonal antibody (MAb) 1604 and by subsequent gel filtration. We propose that the cell surface antigen (CSA) 1604 complex participates in intercellular interactions. The apparent total molecular mass of the CSA 1604 complex is 200 kilodaltons (kDa), as determ...
متن کاملPattern formation by a moving morphogen source.
During Drosophila melanogaster oogenesis, the follicular epithelium that envelops the germline cyst gives rise to an elaborate eggshell, which houses the future embryo and mediates its interaction with the environment. A prominent feature of the eggshell is a pair of dorsal appendages, which are needed for embryo respiration. Morphogenesis of this structure depends on broad, a zinc-finger trans...
متن کاملAdenylate energy charge during fruiting body formation by Myxococcus xanthus.
The adenylate energy charge of developing Myxococcus xanthus cells was measured. The energy charge of vegetative cells (0.81) does not change significantly during the course of fruiting body formation. Furthermore, myxospores, which are resistant, resting cells present in the fruiting body, have a relatively high energy charge (0.73).
