Comparative phylogeography in rainforest trees from Lower Guinea, Africa por Heuertz, M., Duminil, J., Dauby, G., Savolainen, V., Hardy, Olivier J.

“…Comparative phylogeography is an effective approach to assess the evolutionary history of biological communities. We used comparative phylogeography in fourteen tree taxa from Lower Guinea (Atlantic Equatorial Africa) to test for congruence with two simple evolutionary scenarios based on physio-climatic features 1) the W-E environmental gradient and 2) the N-S seasonal inversion, which determine climatic and seasonality differences in the region. …”

Family Flexiviridae: A case study in virion and genome plasticity por Martelli, G.P., Adams, M.J., Kreuze, Jan F., Dolja, V.V.

“…We postulate a common evolutionary ancestor for the family Tymoviridae and the two distinct evolutionary clusters of the Flexiviridae, i.e., a plant virus with a polyadenylated genome, filamentous virions, and a triple gene block of movement proteins. …”

Glycosyltransferase Family 61 in Liliopsida (Monocot): The story of a gene family expansion por Cenci, A., Chantret, Nathalie, Rouard, M.

“…In grasses (Poaceae), a copy number expansion was reported for the GT61 family, which raised the question of the evolutionary history of this gene family. A phylogenetic study was performed on GT61 members from 13 species representing the major angiosperm clades to classify the genes, reconstruct the evolutionary history of this family and study its expansion in monocots. …”

Expanding the Repertoire of the Plant-Infecting Ophioviruses through Metatranscriptomics Data por Debat, Humberto Julio, Garcia, Maria Laura, Bejerman, Nicolas Esteban

“…Here, by exploring large publicly available metatranscriptomics datasets, we report the identification and molecular characterization of 33 novel viruses with genetic and evolutionary cues of ophioviruses. Genetic distance and evolutionary insights suggest that all the detected viruses could correspond to members of novel species, which expand the current diversity of ophioviruses ca. 4.5-fold. …”
