Introduction

Our understanding of cell structure and function is being altered by recent discoveries in bacteria and archaea. It used to be thought that only eukaryotes had complex cell ultrastructure, but now it is clear that all three domains have complex intracellular membranes, organelle structures, and the ability to form extracellular vesicles. A recent investigation into the ultrastructure of bacterial cells revealed a wide variety of unidentified cellular characteristics and structures, indicating that there is still much to be learned. Some of the most intriguing new discoveries in our comprehension of the organization, evolution, and architecture of bacterial and archaeal cells are highlighted in the publications of this Research Topic [1].

Description

Whether complex cell architectures in bacteria and archaea shed light on the origins of eukaryotic cell architecture is an important question. On the one hand, the newly discovered Agars lineages' growing evidence of cellular complexity may help bridge the gap between archaea and the development of the eukaryotic endomembrane system. However, the relationship between eukaryotic cell complexity and bacterial ultrastructure remains a mystery. According to Hendrickson and Poole, one intriguing hypothesis is that distinct structures evolved independently, resulting in similar solutions from very different starting points. Infection with Pseudomonas jumbo phage results in the formation of a nucleus-like barrier, as Chaikeeratisak [2] demonstrates.

Because it suggests that genetic material can be separated from other parts of a cell in a variety of circumstances, the discovery of a phage nucleus is intriguing. The fact that this structure is proteinaceous, in contrast to the eukaryotic nucleus, is a striking feature. The initial mid-cell placement of the phage nucleus and its subsequent rotation during fresh phage assembly are mediated by a spindle of phage-encoded proteins, particularly PhuZ, which is evolutionarily related to tubulin. In order to investigate the distribution of bacterial micro compartments, proteinaceous researchers conduct a survey of the human microbiome. Some BMCs function to trap hazardous aldehyde intermediates generated during metabolic events that take place within these compartments, in contrast to jumbophages, which form a shell to protect the phage genome from degradation by host-encoded defensive mechanisms. In membrane-bounded bacterial compartments like planctomycetes' anammoxosomes, metabolic reactions are also secluded.

With a wide range of complex membrane topologies, Seeger [3] contributes to the diversity of the phylum Planctomycetes. A close relative of the gemmate obscuriglobus, Tuwongella immobilises, is the subject of their in-depth investigation. The question of whether Gemmates' complex cell ultrastructure includes a membrane-bound genetic compartment has been the subject of significant research. Focused Ion Beam Scanning Electron Microscopy tomography was used in this study to show that immobilises does not have such a compartment. Seeger and others, Provide, on the other hand, a picture of a complicated intracellular membrane with tunnels and crannies. They suggest that this could cause distinct molecular processes to be separated spatially [4]. Recent genetic compartmentation in an isolate of the putative phylum Agrobacteria raises the question of whether any bacteria possess nucleus-like compartmentation. It is helpful to keep in mind that the eukaryotic nucleus is a dynamic structure that disassembles during mitosis in many species when considering the difficulties of distinguishing bacterial genetic compartments [5].

Conclusion

Therefore, finding out not only whether bacteria have genetic compartmentation, but also whether it is stable or dynamic, will be fascinating. Another overlooked aspect of prokaryote cell biology is the formation of intercellular bridges, which enable gene transfer and contact between cells. Using a combination of electron cryotomography and fluorescence imaging, they discovered that the archaeon Haloferax volcanic carries a variety of macromolecular complexes, including ribosomes, across these bridges that connect the cytoplasm of mating cells. This demonstrates the extent to which this occurs. Formicate endospore formation and actinobacterial exospore formation is compared by Beskrovnaya. Their findings indicate that formicates have endospores, but that exospores most likely formed after actinobacterial diversification.
