Prokaryotic cell division: flexible and diverse
Current Opinion in Microbiology, 2013Gram-negative rod-shaped bacteria have different approaches to position the cell division initiating Z-ring at the correct moment in their cell division cycle. The subsequent maturation into a functional division machine occurs in vastly different species in two steps with appreciable time in between these.

Cell-to-Cell Communication Across the Prokaryote-Eukaryote Boundary
Science, 2002Bacteria are capable of complex assemblage behavior through cell-to-cell communication using diffusible chemical signal molecules that accumulate to a threshold concentration that activates target genes ([1][1]). This process, termed “quorum sensing,” has not been shown to cross the prokaryote-

Ultrasound-mediated transformation of prokaryotic cells
The Journal of the Acoustical Society of America, 1999Ultrasound-mediated transfection of mammalian cells has been reported in the literature [Kim et al., ‘‘Ultrasound-mediated transfection of mammalian cells,’’ Human Gene Therapy 7, 1339–1346 (July 10, 1996)]. Optimum results were obtained using continuous wave insonification at a carrier frequency of MHz, peak pressures of 319–411 kPa, exposure times of

Evaluation of Prokaryotic and Eukaryotic Cell
Asian Journal of Pharmaceutical Research, 2021In the “ecosystems-first” approach to the origins of life, networks of noncovalent assemblies of molecules (composomes), rather than individual protocells, evolved under the constraints of molecular complementarity. Composomes evolved into the hyperstructures of modern bacteria.

The human cytomegalovirus immediate‐early gene region 1 promoter‐enhancer is active in bacteria and in many mammalian cells. Recombinant plasmids containing portions of this DNA can be used to promote the expression of foreign proteins in many cells.

The ultrastructure of prokaryotic-eukaryotic cell junctions
Journal of Cell Science, 1980ABSTRACT Freeze-fracture and thin-section electron microscopy were used to describe the sites of attachment of 2 kinds of ectosymbiotic bacteria to a devescovinid flagellate from termites. In each case, surface specializations in both partners occur at the junctional complexes. Rod bacteria lie in pockets of the eukaryotic membrane which

The photosynthetic membrane: prokaryotic and eukaryotic cells
Endeavour, 1985Abstract Photosynthesis is one of the most important of all biochemical progresses, occuring not only in green plants but in certain algae and bacteria. This article reviews current ideas about the mechanisms of photosynthesis, with special reference to the role of photosynthetic membranes.
