Beschreibung
Molecular diffusion limits cell size and therefore, only a minority of bacterial species develop unusual large sizes in nature. Despite their unique cell biological properties, the molecular basis of their reproduction is scarcely known. The filamentous bacteria associated to two species of marine symbiotic nematodes, Eubostrichus fertilis and dianeae, are sulfur-oxidizing Gammaproteobacteria. The former is crescent-shaped and can be up to 45 ľm long, whereas the latter forms up to 120 ľm long filaments. By morphometric and immunohistochemical analysis, we showed that, despite their extraordinary length and polyploidy, bothGammaproteobacteria reproduce by symmetric FtsZ-based fission i.e. they place a single FtsZ ring at midcell. Surprisingly, in the E. fertilis symbiont formation of a single, medially localized division apparatus is independent of cell length. This is the first investigation of the cellular and molecular basis of reproduction of unusually long, environmental bacteria.| Zeitraum | 15 Dez. 2013 |
