Example sentences for: enterobacteriales
How can you use “enterobacteriales” in a sentence? Here are some example sentences to help you improve your vocabulary:
A number of taxa do show arsC phylogenies that are inconsistent with the established 16S rRNA evolutionary tree, perhaps the most dramatic being the separation of some of the non-enteric γ-Proteobacteria ( Pseudomonas putida , P. aeruginosa , and A. ferrooxidans ) from the Enterobacteriales.
For example, the arsC sequences from major divisions of Bacteria such as the Green Sulfur Bacteria (represented by Chlorobium tepidum ) and the Deinococcales (represented by D. radiodurans ) are loosely associated with either the Enterobacteriales/α-Proteobacteria (Figure 2) or Low GC Gram-positive Bacteria (Figure 3) depending upon the analysis used, but in either case diverge to form their own deep branches, suggesting that they possess distinct arsenate reductases.
The plasmid-borne arsC gene from Salmonella typhimurium , shows little similarity to it's chromosomal equivalent, and appears to be related to the other arsC genes found in plasmids in the Enterobacteriales.
The non-enteric γ-Proteobacteria actually appear to be paraphyletic with regards to arsC , in that the two Xanthomonas species group with the α-Proteobacteria, whereas the others form a distinct group with the sole representative of the β-Proteobacteria ( R. solanacearum ). The phylogenetic affiliation of the latter clade is uncertain: ED analysis placed it as a deep branch in the Low GC Gram positive Bacteria group (Figure 2), whereas MP placed it loosely with the large Enterobacteriales/α-Proteobacteria group (Figure 3).
Either placement had poor bootstrap support, and given the relatively low sequence homology of this clade to either of the other major bacterial arsC groups (50% similarity to the Low GC Gram positives, 40% similarity to the Enterobacteriales/α-Proteobacteria group) we suspect that this group might represent a fourth distinct group of arsenate reductases, making its placement in a binary tree difficult.
