D’Afonseca","doi":"10.4238/gmr19003","DOIUrl":"https://doi.org/10.4238/gmr19003","url":null,"abstract":"\"The challenge presented by the SARS-CoV-2 pathogen has changed the global perception about virus diseases. In Wuhan, China the first case of the disease called COVID-19 (Coronavirus Disease 2019) was reported in December 2019 and quickly reached 215 countries. The pathogenic SARS-CoV-2 virus has an RNA genome composed of a positive-sense single-strand, harboring 14 ORFs that encode 50 proteins composed of typical structural proteins. The spike protein, a surface glycoprotein, is essential for the invasion of the causal agent of COVID-19 into the host system. Several variants have specific mutations in protein S that affect transmission processes, diagnosis, and available therapies. Entry of SARS-CoV-2 into the host cell promotes immunological dysregulation with increased expression of interferon type 1 and an exaggerated proinflammatory cytokine event called \"\"cytokine storm\"\". This event is often associated with deleterious outcomes such as acute respiratory distress syndrome. In addition, substantial immunological memory can be generated after initial SARS-CoV-2 infection, involving four major cell types, such as anti-spike protein memory B cells (RBD IgG, IgM), T cells (CD4+ and CD8+) and other molecules, such as antibodies. It is important to collect genetic and immunological information related to the SARS-CoV-2 virus to provide a global vision and high quality knowledge about the biology and this disease in order to develop effective control measures and treatments.

To date, various methodologies have been applied, including metagenomic approaches and amplicon-based sequencing associated with high-throughput sequencing platforms. We adapted some details in amplicon-based sequencing using a SARS-CoV-2 community panel (Illumina AmpliSeq), with additional modifications for balanced and high-quality sequencing using the MiSeq platform. The modified protocol was used to detect circulating SARS-CoV-2 variants in Goias state, Brazil. Initially, RNA samples were obtained from swab samples from 15 patients from the state of Goias, Brazil, in November/2020 and February/2021 to validate protocol steps. The libraries were prepared following AmpliSeq for Illumina workflow with modifications;subsequently, we analyzed 305 positive samples collected from the state of Goias from December 2020 to July 2021. For protocol improvement, we removed the need to treat samples with DNAse and demonstrated the importance of quantification by qPCR before and after library dilution. No fragmentation pattern was observed in the samples analyzed with Bioanalyzer. The libraries returned sequencing results that were used for genome assembly and variant detection. We were able to assemble SARS-CoV-2 genomes from 318 samples, which were used to identify 13 variants of coronavirus circulating in Goias throughout those months. Variants of concern, such as Alpha (B.1.1.7), Gamma (P.1) and Delta (B.1.617.2) were detected;the latter was detected at first in Goias in April 2021. The modifications in the workflow we developed were successfully applied to detect SARS-CoV-2 variants, resulting in high coverage genome assembly, and they can be used to increase the number of genome sequences and aid in epidemiological surveillance in Brazil.","PeriodicalId":12518,"journal":{"name":"Genetics and Molecular Research","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70935639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the purpose was to determine the additive and non-additive effects that affect the genetic control of common bean roots. A field experiment, with 75 treatments in a partially balanced incomplete block design, was carried out in the 2018/19 growing season. The treatments consisted of backcross progenies (L1 P1 x F2, L2 P2 x F2 and L3 F1 x F2) resulting from a Triple Test Cross mating design, with the Mesoamerican parents P1-BAF50 (accession of the active germplasm bank) and P2-IPR Uirapuru (commercial cultivar). The trait root distribution was assessed based on the soil excavation method, in situ. To this end, trenches were opened under each plant (two plants per replication, in each treatment) and a grid was inserted in the open profile. Pictures were taken of the grid in the trench, based on which the root distribution (percentage) could be quantitatively assessed. To compare root and shoot biomass, the numbers of pods and grains were counted at harvest. The treatment factor was partitioned into genetic effects (additive, dominant and epistatic) by the establishment of predictive functions. The additive genetic effect was the most","PeriodicalId":12518,"journal":{"name":"Genetics and Molecular Research","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70934849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
