Words similar to alpha-proteobacteria
Example sentences for: alpha-proteobacteria
How can you use “alpha-proteobacteria” in a sentence? Here are some example sentences to help you improve your vocabulary:
Our results show clear evidence of a trans-domain transfer of a GshA gene from alpha-proteobacteria to plants.
Many of the alpha-proteobacteria are either plant pathogens (for example, Agrobacterium tumefaciens ) or plant commensals (for example, Sinorhizobium meliloti and Zymomonas mobilis ). The close physical association between these bacteria and plants apparently provided an opportunity for lateral transfer of the GshA gene, perhaps more than 300 million years ago.
The gamma-proteobacteria represented in group 1 are reasonably closely related to the alpha-proteobacteria in group 3, and the crown eukaryotes in group 2 are reasonably closely related to the plants in group 3. Orthologous relationships between these groups can often be identified.
For this purpose, we used five closely related genomes in the enterobacteria group: E. coli O157:H7 EDL933 [ 11 ] , E. coli O157:H7 Sakaï [ 29 ] , E. coli K12 [ 30 ] , Salmonella enterica [ 31 ] , and S. typhimurium LT2 [ 10 ] ; three closely related genomes in the alpha-proteobacteria group: Helicobacter pylori J99 [ 32 ] , H. pylori 26695 [ 33 ] , and Campylobacter jejunii [ 34 ] ; and three closely related genomes in the Streptococcus genus: S. pneumoniae R6 [ 35 ] , S. pneumoniae TIGR4 [ 36 ] , and S. pyogenes [ 12 ] . We considered as unambiguous the relationships between these bacteria because, for example, the orthologous genes of the two strains of E. coli O157:H7 are almost identical at the nucleotide level, while they show noticeable differences from E. coli K12 (data not shown).
Lateral gene transfer from alpha-proteobacteria to plants is particularly intriguing because transfer and retention of a foreign gene in a sophisticated multicellular organism is more difficult than in bacteria.
