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:

  • 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.

  • 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.

  • Our results show clear evidence of a trans-domain transfer of a GshA gene from alpha-proteobacteria to plants.

  • The first group consists primarily of gamma-proteobacteria, the second of non-plant eukaryotes and the third primarily of flowering plants and alpha-proteobacteria.

  • 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.
