Computational studies that analyzed HGT events among bacterial genomes revealed that HGT frequency positively and strongly correlates with the similarity of tRNA pools between donors and acceptors
HGT typically adds new catabolic routes to microbial metabolic networks. This increases the chance of new metabolic interactions between bacteria
We tested a broad range of Enterobacteriaceae conjugative plasmids for their sensitivity to the growth stage of the donors and identified three distinct regulation types.
In soil, bacteria tend to live in a state of dormancy due to prevailing oligotrophic conditions, which would not be particularly favorable for the development of competence
It can also be argued that the transformed DNA is a good resource of phosphates, nitrogen etc., so might be favoured in oligotrophic conditions?
In culture conditions that enhance cell-to-cell contact, conjugation rates approach 100% with the cis-acting plasmid
high efficiency
absence of nitrogen was found to increase HGT events three orders of magnitude
