When viewed under light microscope, most bacteria appear in variations of three major shapes: the rod (bacillus), the sphere (coccus) and the spiral type (vibrio). In fact, structure of bacteria has two aspects, arrangement and shape. So far as the arrangement is concerned, it may Paired ...
One potentially widespread interaction that may shape the dynamics of bacterial cell dispersal is the migration of bacterial cells on fungal hyphae16,17. Multicellular filamentous fungi form mycelial networks that enable bacteria to migrate across simplified environments16,18. The specific biological and p...
In order to maintain shape and withstand intracellular pressure, most bacteria are surrounded by a cell wall that consists mainly of the cross-linked polym... DJ Scheffers,MG Pinho - 《Microbiology & Molecular Biology Reviews Mmbr》 被引量: 712发表: 2006年 Bacterial cell shape. Bacterial specie...
In the absence of an overt cytoskeleton, the external cell wall of bacteria has traditionally been assumed to be the primary determinant of cell shape. In the Gram-positive bacterium Bacillus subtilis, two related genes, mreB and mbl, were shown to be required for different aspects of cell mor...
The Great Wall: Peptidoglycan Is a Primary Determinant of Bacterial Cell Shape In Caulobacter, as in almost all bacteria, the peptidoglycan (PG) cell wall is both necessary and sufficient to maintain cell shape. The cell wall resides just outside the cytoplasmic membrane and is one large, coval...

These null-model-based inferences were supported by neutral modelling, which estimated a dispersal rate almost two orders-of-magnitude lower for fungi than bacteria. This indicates that while stochastic processes are important for fungal assembly, bacteria were more influenced by deterministic selection ...
