Electric eels galore: microsatellite markers for population studies

Neotrop. ichthyol; 18 (4), 2020
Fourteen novel microsatellite loci are described and characterized in two species of electric eels, Electrophorus variiand E. voltaifrom floodplains and rivers of the Amazon rainforest. These loci are polymorphic, highly informative, and have the capacity to detect reliable levels of genetic diversity. L...

Parámetros forenses de diez microsatélites del cromosoma X en una muestra de la población del Estado Zulia, Venezuela
Forensic parameters of ten X chromosome microsatellites polymorphisms in a sample of the Zulia State population, Venezuela

Justificación:Las repeticiones cortas en tándem (STRs) están distribuidos por toda la extensión del genoma humano, los ubicados en los cromosomas autosómicos y en el cromosoma Y han sido ampliamente utilizados en los laboratorios de genética forense debido a las ...

Características histopatológicas del carcinoma colorrectal con inestabilidad microsatelital (IMS)

Repert. med. cir; 29 (1), 2020
El carcinoma colorrectal es una de las neoplasias con mayor incidencia a nivel mundial. Algunos de los tipos tienen componente hereditario y asociación con defectos en la reparación génica a nivel replicacional, por mutaciones en los genes encargados (MLH1, MSH2, MSH6 y PMS2), llam...

Microsatellite loci development for three catfish species from northwestern South America

Neotrop. ichthyol; 18 (1), 2020
The Neotropical catfish species Ageneiosus pardalis, Pimelodus grosskopfii, and Sorubim cuspicaudus are important fishery resources in Colombia that show historical declines in their capture. This study used next-generation sequencing with 454 FLX technology (Roche Applied Science) and bioinformatics ana...

Production of wheat-doubled haploids resistant to eyespot supported by marker-assisted selection

BACKGROUND: Wheat is one of the most important crops cultivated all over the world. New high-yielding cultivars that are more resistant to fungal diseases have been permanently developed. The present study aimed at the possibility of accelerating the process of breeding new cultivars, resistant to eyespo...

Identificación genética de recién nacidos en Perú: un estudio piloto

Rev. chil. pediatr; 90 (1), 2019
OBJETIVO: Determinar la factibilidad de la identificación genética a un grupo de recién nacidos prove nientes de un hospital público de Lima-Perú. MATERIAL Y MÉTODO: Estudio descriptivo de corte trans versal, realizado por Registro de Identificación y Estado Civil de Perú, en recién nacidos viv...

The genetic diversity of wild and cultivated Manila clam (Ruditapes philippinarum) revealed by 29 novel microsatellite markers

Background: Microsatellite loci often used as a genetic tool for estimating genetic diversity population variation in a wide variety of different species. The application of microsatellite markers in genetics and breeding includes investigating the genetic differentiation of wild and cultured populations...

Comparison of the phenolic contents and epigenetic and genetic variability of wild and cultivated watercress (Rorippa nasturtium var. aquaticum L.)

Background: Epigenetic modifications are key factors modulating the expression of genes involved in the synthesis of phytochemicals. The knowledge of plant epigenetic and genetic variations can contribute to enhance the production of bioactive compounds. These issues have been little explored thus far in...

Monitoramento e controle de mosquitos vetores: uma proposta para avançar no conhecimento e no controle de Aedes aegypti e Aedes albopictus

Aedes aegypti é o principal vetor de arbovírus ao homem, como o dengue, Zika e chikungunya. Como não existem tratamentos específicos e vacinas disponíveis, exceto para a dengue, o controle desses patógenos se dá mais comumente pelo combate ao vetor. Por este motivo, os inseticidas constituem-se a ...

Development and characterization of microsatellite markers in Gaultheria pumila Lf. (Ericaceae)

Biol. Res; 51 (), 2018
BACKGROUND: Polymorphic microsatellite markers were developed for Gaultheria pumila (Ericaceae) to evaluate genetic diversity and population structure within its native range in Chile. This is a very important Ericaceae endemic to Chile with a large commercial potential. Its resistance to different abiot...
