Whole genome sequencing data and de novo draft assemblies for 66 teleost species
2017
Teleost fishes comprise more than half of all vertebrate species, yet genomic data are only available for 0.2% of their diversity. Here, we present whole genome sequencing data for 66 new species of teleosts, vastly expanding the availability of genomic data for this important vertebrate group. We report on de novo assemblies based on low-coverage (9–39×) sequencing and present detailed methodology for all analyses. To facilitate further utilization of this data set, we present statistical analyses of the gene space completeness and verify the expected phylogenetic position of the sequenced genomes in a large mitogenomic context. We further present a nuclear marker set used for phylogenetic…
Diversity and Evolution of papillomaviruses

1.1. Introducción Con el fin de averiguar las causas de las devastadoras epidemias de finales del siglo XIX, se llevaron a cabo diferentes estudios que dieron como resultado la identificación de unos nuevos agentes infecciosos, para los que se acuñó el nombre de “virus”. Desde entonces el descubrimiento de nuevos virus ha sido incesante, lo que llevó, en los años 70, a la creación de un organismo encargado de desarrollar, refinar y mantener la clasificación taxonómica de los virus, el Comité Internacional de Taxonomía Viral (ICTV), en el seno de la Unión Internacional de Sociedades Microbiológicas (IUMS). En 2014 este organismo había reconocido 3.186 especies virales pertenecientes a 104 fa…
On the hybrid origin of the C2Salsola divaricata agg. (Amaranthaceae) from C3 and C4 parental lineages
2021
AbstractC2 photosynthesis is characterized by recapturing photorespiratory CO2 by RuBisCO in Kranz-like cells and is therefore physiologically intermediate between C3 and C4 photosynthesis. C2 can be interpreted as an evolutionary precursor of C4 and/or as the result of hybridization between a C3 and C4 lineage.We compared the expression of photosynthetic traits among populations of the Salsola divaricata agg. (C2) from humid subtropical to arid habitats on the coasts of the Canary Islands and Morocco and subjected them to salt and drought treatments. We screened for enhanced C4-like expression of traits related to habitat or treatment. We estimated species trees with a transcriptome datase…
Data from: From cacti to carnivores: improved phylotranscriptomic sampling and hierarchical homology inference provide further insight into the evolu…

Premise of the Study— The Caryophyllales contains ~12,500 species and is known for its cosmopolitan distribution, convergence of trait evolution, and extreme adaptations. Some relationships within the Caryophyllales, like those of many large plant clades, remain unclear and phylogenetic studies often recover alternative hypotheses. We explore the utility of broad and dense transcriptome sampling across the order for resolving evolutionary relationships in Caryophyllales. Methods— We generated 84 transcriptomes and combined these with 224 publicly available transcriptomes to perform a phylogenomic analysis of Caryophyllales. To overcome the computational challenge of ortholog detection in su…
