Control of Cell Morphogenesis in Bacteria Two Distinct Ways to Make a Rod-Shaped Cell
Cell shape in most eubacteria is maintained by a tough external peptidoglycan cell wall. Recently, cell shape determining proteins of the MreB family were shown to form helical, actin-like cables in the cell. We used a fluorescent derivative of the antibiotic vancomycin as a probe for nascent peptidoglycan synthesis in unfixed cells of various Gram-positive bacteria. In the rod-shaped bacterium...
متن کاملMicrostructure of colonies of rod-shaped bacteria.
Whole colonies of Bacillus cereus, B. megaterium, B. mycoides CN2495, Corynebacterium hofmanni NCTC1938, Escherichia coli, Lactobacillus acidophilus NCIB1899, Nocardia graminis NCTC4728, Pseudomonas viscosa, and Serratia marcescens were prepared for scanning electron microscopic examination by freeze-drying and metal-coating. The arrangement of individual cells within colonies could be seen. Ce...
متن کاملBistable protein distributions in rod-shaped bacteria
The distributions of many proteins in rod-shaped bacteria are far from homogenous. Often they accumulate at the cell poles or in the cell center. At the same time, the copy number of proteins in a single cell is relatively small making the patterns noisy. To explore limits to protein patterns due to molecular noise, we studied a generic mechanism for spontaneous polar protein assemblies in rods...
متن کاملInvestigation of cytotoxicity properties of zinc oxide nanoparticles in spherical and rod shaped on leukemia cells
In this study, we reported a method to associate doxorubicin drug on folic acid functionalized SiO2/ZnO nanoparticles (NPs) in rod and spherical shapes. The clinical usage of the anticancer drug, doxorubicin (DOX), is limited by severe side effects and cell resistance. Targeted drug delivery by binding DOX to nanoparticles could overcome these limitations. The surface functionalization of the Z...
متن کاملContrasting mechanisms of growth in two model rod-shaped bacteria
How cells control their shape and size is a long-standing question in cell biology. Many rod-shaped bacteria elongate their sidewalls by the action of cell wall synthesizing machineries that are associated to actin-like MreB cortical patches. However, little is known about how elongation is regulated to enable varied growth rates and sizes. Here we use total internal reflection fluorescence mic...
