Objectives Elaeis oleifera, commonly known as the American oil palm, plays a crucial role in the agricultural economies of Central and South America due to its unique oil characteristics and resistance to certain diseases. Despite its importance, limited available genetic information has hindered the effective utilization of this species in breeding programs aimed at improving oil yield and disease resistance. This study employed Genotyping-bySequencing (GBS) to profile polymorphisms within Elaeis oleifera populations, the unique germplasm bank for Peru, located in Ucayali, Peru, aiming to characterize the gene pool. Data description The GBS analysis successfully identified 22,703 informative single-nucleotide polymorphisms (SNPs) across the twelve-year-old plant genomes (n=42). Observed heterozygosity (Ho=0.3086) and expected heterozygosity index (He=0.3385) were quantified. The fixatio...

Introduction: Currently, infections by the SARS-CoV-2 virus exceed 600 million cases in the world. Objective: Isolation and characterization of the SARS-CoV-2 virus causing COVID-19 at the beginning of the pandemic in Peru. Materials and methods: Twenty nasal and pharyngeal swab samples were isolated SARS-CoV-2 using two cell lines, Vero ATCC CCL-81 and Vero E-6; virus identification was performed by RT-PCR and the onset of cytopathic effect (CPE) was evaluated by indirect immunofluorescence and subsequent identification by genomic sequencing. One of the most widely circulating isolates was selected and named the prototype strain (PE/B.1.1/28549/2020). Then 10 successive passages were performed in Vero ATCC CCL-81 cells to assess mutation dynamics. Results: Results detected 11 virus isolates by cytopathic effect, and subsequently confirmed by RT-PCR and indirect immunofluorescence. Of th...
