Assessment of genetic diversity in chinese hulless barley accessions for qualitative traits

Biosci. j. (Online); 37 (), 2021
Cultivated barley (Hordeum vulgare L.) has been proven to be an economically important model plant and having large genetic diversity among the species. The effective exploitation of qualitative characters in barley can be measured by its genetic diversity and interrelationship. This study aims to determ...

Genetic diversity among cassava genotypes (Manihot esculenta crantz) collected in the south-central mesoregion of the state of Mato Grosso-Brazil

Biosci. j. (Online); 37 (), 2021
The aim of this research was to evaluate the genetic divergence between 164 genotypes of Manihot esculenta from the South-Central mesoregion of the State of Mato Grosso. The genotypes are from projects conducted by the Laboratory of Genetic Resources & Biotechnology of the University of the State of Mato...

Genetic diversity and structure in natural populations of Cajui from Brazilian Cerrado

Biosci. j. (Online); 37 (), 2021
Cajui (Anacardium spp.) is a native fruit tree (small cashew) of the Brazilian Cerrado and possesses the potential for commercialization. However, cajui exploitation occurs exclusively through extractivism in the absence of conservation strategies. The lack of conservation strategies may lead to a decrea...

A simple and cost-effective method for DNA extraction suitable for PCR in “sucupira branca”

Biosci. j. (Online); 37 (), 2021
“Sucupira branca” is a plant found in the Brazilian Cerrado and is adapted to low fertility soils, and its fruit extract has anti-inflammatory, healing, antiulcerogenic, antimicrobial, cercaricidal, leishmanicidal and antioxidant activities. Furthermore, it provides protection against oxidative stres...

Determination of investigation of the link between human and animal Brucella isolates in Iran using multiple-locus variable number tandem repeat method comprising 16 loci (MLVA-16)

Braz. j. infect. dis; 25 (1), 2021
ABSTRACT Background: Epidemiological studies are important tools to assess the diversity of Brucella isolates and to estimate their epidemiological relationship among isolates from different geographical origins. In this study the MLVA16 (multiple-locus variable number tandem repeat analysis based on 16...

Human immunodeficiency virus infection and syphilis among homeless people in a large city of Central-Western Brazil: prevalence, risk factors, human immunodeficiency virus-1 genetic diversity, and drug resistance mutations

Braz. j. infect. dis; 25 (1), 2021
ABSTRACT Homeless people are at high risk for sexually transmitted infections (STIs), such as human immunodeficiency virus (HIV) infection and syphilis. We investigated the epidemiology of HIV-1 infection and syphilis among homeless individuals in a large city in Central-Western Brazil. In this cross-sec...

Large-scale advances in SSR markers with high-throughput sequencing in Euphorbia fischeriana Steud

Electron J Biotechnol; 49 (), 2021
BACKGROUND: Euphorbia fischeriana Steud is a very important medicinal herb and has significant medical value for healing cancer, edema and tuberculosis in China. The lack of molecular markers for Euphorbia fischeriana Steud is a dominant barrier to genetic research. For the purpose of developing many sim...

Development of Kompetitive Allele Specific PCR markers for identification of persimmon varieties using genotyping-by-sequencing

Electron J Biotechnol; 49 (), 2021
BACKGROUND: Persimmon (Diospyros kaki Thunb.) is the most widely cultivated species of the genus Diospyros. In this study, genetic diversity and variations in persimmon genotypes were investigated using single nucleotide polymorphism (SNP) markers identified by genotyping-by-sequencing (GBS) analysis. RE...

Vibrio sp. ArtGut-C1, a polyhydroxybutyrate producer isolated from the gut of the aquaculture live diet Artemia (Crustacea)

Electron J Biotechnol; 49 (), 2021
BACKGROUND: Vibrio species display variable and plastic fitness strategies to survive and interact with multiple hosts, including marine aquaculture species that are severely affected by pathogenic Vibrios. The culturable Vibrio sp. strain ArtGut-C1, the focus of this study, provides new evidence of such...

Bioinformática como recurso educativo para enseñar variabilidad genética mediante la comparación de mapas de restricción

Uno de los rasgos de la sociedad del siglo XXI es la incorporación de las TIC en la educación, las cuales pueden contribuir en los procesos de enseñanza-aprendizaje. Sin embargo, el maestro es quien le dá el sentido pedagógico a estos recursos educativos. En ese sentido, las herramientas de la bioin...
