How and why cells grow as rods
WebStructure. Rods are a little longer and leaner than cones but have the same basic structure. Opsin-containing disks lie at the end of the cell adjacent to the retinal pigment … Web8 de jun. de 2024 · Spheres and rods are among the most common shapes adopted by walled bacteria, in which the peptidoglycan (PG) cell wall largely determines cell shape. When induced by chemicals, rod-shaped vegetative cells of the Gram-negative bacterium Myxococcus xanthus thoroughly degrade their PG and shrink into spherical spores.

In contrast to E. coli, some rod-shaped cells grow via insertion of new cell wall and membrane at the cell tips, while the lateral wall is relatively inert. Mechanisms of tip growth have been investigated in many walled organisms, including S. pombe, hyphal fungi, moss, and pollen tubes, as well as in bacteria such as … Ver mais Rod-shaped growth ultimately requires a breaking of symmetry, which can arise from directionality in the material properties of the cell … Ver mais In many bacteria, cell growth is achieved by insertion of new cell-wall material at sites throughout the cylindrical part of the cell wall, while insertion is decreased at cell poles. The most well studied organism from the perspective … Ver mais In addition to propagation of shape during growth, cells can face the challenge of initial establishment of shape.
