Non-thermal plasma is an alternative to conventional sterilization methods [5] and is considered as a new sterilization technique in the conservation of materials from bacteria [4].
The high functional conservation of T3SS in bacteria and the presence of a single ATPase per virulence system suggest a critical role for the ATPase protein in the function of T3SS.
The metabolic pathway of the histidine biosynthesis, reactions, enzymes, as well as the organization of the corresponding genes display a high degree of conservation in bacteria [ 49].
Given the high degree of conservation of rRNA sequences in bacteria, each read could only be unambiguously classified at the genus level (or at the family level in the case of Enterobactericeae) (Fig. 4).
These observations reinforce the conservation of these functions in bacteria, since similar results were previously obtained for other microorganisms [ 33].
The preferential selection of specific rhizobia strains is likely a major reason supporting the conservation of the plant and bacteria genes required for mutualism [ 31].
Since the topology of bacteria co-conservation protein-protein interaction networks has not previously been studied in depth, we first perform such an analysis for co-conservation networks in E. coli K12.
Given the high conservation of SlmA in Gram-negative bacteria, we propose that this NO mechanism is likely used by all bacteria that harbour a SlmA protein.
The conservation of KerV in non-pathogenic bacteria also proposes that it is likely important in other ecological settings besides plant and animal infections, such as beneficial bacteria-host interactions and environmental processes.
Previous studies have illustrated the conservation of antisense transcription separately in bacteria [ 3], yeasts [ 18] and mammals [ 12, 19].
