Phylogeny of nodulation and nitrogen-fixation genes in Bradyrhizobium: supporting evidence for the theory of monophyletic origin, and spread and maintenance by both horizontal and vertical transfer.
(International Journal of Systematic and Evolutionary Microbiology, 61, p. 3052-3067, Feb. 2011., 2011)
Exploring the ancestral mechanisms of regulation of horizontally acquired nitrogenases
(Springer, 2015-10)
The vast majority of Pseudomonas species are unable to fix atmospheric nitrogen. Although several studies have demonstrated that some strains belonging to the genus Pseudomonas sensu stricto do have the ability to fix ...
Whitefly genomes contain ribotoxin coding genes acquired from plants
(Nature Publishing Group, 2020-12)
Ribosome inactivating proteins (RIPs) are RNA N-glycosidases that depurinate a specific adenine residue in the conserved sarcin/ricin loop of 28S rRNA. These enzymes are widely distributed among plants and bacteria. ...
Reticulate evolution in eukaryotes: Origin and evolution of the nitrate assimilation pathway
(Public Library of Science, 2019-02)
Genes and genomes can evolve through interchanging genetic material, this leading to reticular evolutionary patterns. However, the importance of reticulate evolution in eukaryotes, and in particular of horizontal gene ...
Metagenomic strategies identify diverse integron-integrase and antibiotic resistance genes in the Antarctic environment
(John Wiley & Sons Inc., 2021-10)
The objective of this study is to identify and analyze integrons and antibiotic resistance genes (ARGs) in samples collected from diverse sites in terrestrial Antarctica. Integrons were studied using two independent methods. ...
