“…In this study, we assembled high-quality genomes of a common warthog (Phacochoerus africanus), a red river hog (Potamochoerus porcus), as well as an East Asian Diannan small-ear pig (Sus scrofa). Phylogenetic analysis showed that common warthog and red river hog diverged from their common ancestor around the Miocene/Pliocene boundary, putatively predating their entry into Africa. …”

“…We collected 152 individuals from 20 localities throughout the species’ range, ran genetic and demographic analyses, and applied ecological niche modeling. Phylogenetic and population genetic analyses based on cpDNA and AFLP data identified three phylogroups that correspond to the previously identified subregions within the SATZ. …”

Molecular characterization of yerba mate chlorosis-associated virus, a putative cytorhabdvirus infecting yerba mate (Ilex paraguariensis) por Bejerman, Nicolas Esteban, De Breuil, Soledad, Debat, Humberto Julio, Miretti, Marcos, Badaracco, Alejandra, Nome Docampo, Claudia

“…Seven open reading frames (ORFs) were identified in the antigenomic orientation of the negative-sense, single-stranded viral RNA, in the order 3′-N-P-P3-P4-M-G-L-5′. Phylogenetic analysis suggested that the described virus is a new member of the genus Cytorhabdovirus, which was supported by the observation of rhabdovirus-like particles within the cytoplasm of infected yerba mate cells. …”

Ancient Human Mitogenome of the Beagle Channel (Tierra del Fuego): An Argentine Collaborative Project por Arencibia, Valeria, Muñoz Hidalgo, Marianne Graziel, Crespo, Cristian, Maldonado, Lucas, Lichtenstein, Gabriel, Kamenetzky, Laura, Vera, Pablo Alfredo, Zangrando, Atilio F., Tessone, Augusto, Avena, Sergio, Lia, Veronica Viviana, Puebla, Andrea Fabiana, Dejean, Cristina

“…To obtain an ancient mitogenome in Argentina, several institutions collaborated to apply massively parallel sequencing and bioinformatic methodologies on an enriched ancient DNA library of an individual from the Beagle Channel (dated 1504 ± 46 years BP), a region of particular interest for this line of inquiry. Phylogenetic reconstruction showed a close relationship with a Yamana from Navarino Island and an individual from Hoste Island (Chilean Antarctic Province): the three shared an ancestor who lived between 203 and 4,439 years ago. …”

Morphological and molecular identification of the invasive Xylosandrus crassiusculus (Coleoptera: Curculionidae: Scolytinae) and its South American range extending Into Argentina a... por Landi, Lucas, Gómez, Demian, Braccini, Celina Laura, Pereyra, Vanina Antonella, Smith, Sarah M., Marvaldi, Adriana Elena

“…Molecular identification was also done on the basis of the 5′ region of the mitochondrial cytochrome c oxidase I (COI) gene, obtained from a specimen from Argentina and compared with available “barcode” sequences in public databases. Phylogenetic analyses, via maximum likelihood and parsimony, were performed using COI sequences from 17 terminals, including 14 sequences of X. crassiusculus from different continents plus other Xylosandrus and Cnestus species as outgroups. …”

Leptospira species molecular epidemiology in the genomic era por Caimi, Karina Cynthia, Repetto, Silvia A., Varni, Vanina Delia, Ruybal, Paula

“…The correlation observed between STs and serogroups in our previous work, is still satisfied with this higher dataset sustaining the implementation of MLST to assist serological classification as a complementary approach. Bayesian phylogenetic analysis of concatenated sequences from R7-MLST loci allowed us to resolve taxonomic inconsistencies but also showed that events such as recombination, gene conversion or lateral gene transfer played an important role in the evolution of Leptospira genus. …”

Novel bird’s-foot trefoil RNA viruses provide insights into a clade of legume-associated enamoviruses and rhabdoviruses por Debat, Humberto Julio, Bejerman, Nicolas Esteban

“…The genome of the proposed “bird’s-foot trefoil-associated virus 2” (BFTV-2) is 5,736 nt long with a typical 5΄-PO-P1-2-IGS-P3-P5-3′ enamovirus genome structure. Phylogenetic analysis indicated that BFTV-1 is closely related to datura yellow vein nucleorhabdovirus and that BFTV-2 clusters into a monophyletic lineage of legume-associated enamoviruses. …”
