Genetic diversity and differentiation of nine populations of the hard clam (Meretrix petechialis) assessed by EST-derived microsatellites

BACKGROUND: Meretrix petechialis is one of the commercially important marine bivalves. In this study, we selected six highly polymorphic EST-derived microsatellite markers to assess the genetic diversity and population differentiation on nine wild populations of Meretrix petechialis. RESULTS: The number ...

Genetic diversity of Euterpe edulis martius based on fruit traits

Biosci. j. (Online); 36 (5), 2020
Juçara (Euterpe edulis Martius) is a palm species from the Atlantic Forest whose fruits are important as a source of food to several individuals from the fauna of the region. Despite its ecological importance, juçara is found in the list of endangered species, due to the fragmentation of the forests an...

Genetic diversity and population structure of endangered rosewood from the Peruvian Amazon using ISSR markers

Acta amaz; 50 (3), 2020
Rosewood, Aniba rosaeodora is an endangered species in Amazon forests and its natural stands have been heavily depleted due to over-exploitation for the cosmetic industry. This study aimed to investigate the genetic diversity and population structure of 90 rosewood accessions from eight localities in the...

Transferability of heterologous primers in Brycon falcatus

Acta amaz; 50 (3), 2020
The genus Bryconcomprises fish species of significant socioeconomic and biological importance in Brazil. Despite that, the genetic knowledge about these species is scarce, especially regardingBrycon falcatus. Thus, the objective of this study was to evaluate the transferability of heterologous microsatel...

Analysis of the population structure and genetic diversity of the red swamp crayfish (Procambarus clarkii) in China using SSR markers

BACKGROUND: Procambarus clarkii produces high-quality, delicious meat that is high in protein, low in fat, and rich in calcium and phosphorus. It has become an important aquatic resource in China. Our objectives are (i) to analyze the level of genetic diversity of P. clarkii populations; (ii) to explore ...

Molecular variation of Plasmodium vivax dehydrofolate reductase in Mexico and Nicaragua contrasts with that occurring in South America

Salud pública Méx; 62 (4), 2020
Abstract: Objective: To research mutations associated to pyrimethamine resistance in dihydrofolate reductase (pvdhfr) of Plasmodium vivax from Mexico and Nicaragua and compare it to that reported in the rest of America. Materials and methods: Genomic DNA was obtained from P. vivax-infected blood samp...

Diversidad genética de plasmodium falciparum
Genetic diversity of Plasmodium falciparum

La diversidad genética le confiere a Plasmodium falciparum la capacidad de evadir la respuesta inmune del hospedero y producir variantes resistentes a medicamentos y a vacunas. Diferentes autores han documentado la existencia de cepas o clones de P. falciparum, cuya diversidad genética se ha confirmado...

Genetic diversity among wild pomegranate (Punica granatum) in Azad Jammu and Kashmir region of Pakistan

BACKGROUND: Pomegranate (Punica granatum L.), one of the most important tropical fruits in Azad Jammu and Kashmir regions of Pakistan, is highly valued for its nutrition and medicinal purposes. Although pomegranate is native to this region, the genetic diversity among wild pomegranate accessions is curre...
