Genetic diversity; kdr; Mechanism of resistance; Mosquito

Recently, the number of Aedes aegypti foci has increased in west of Santa Catarina, south Brazil, which has increased concern regarding mosquito-borne disease outbreaks such as dengue fever, Zika virus, and chikungunya. Therefore, it is important to monitor genetic resistance to insecticides through “knockdown resistance”. Homozygosity (Ile/Ile) at ... more

We previously described a novel densovirus [Myzus persicae nicotianae densovirus (MpnDV)] infecting M. persicae nicotianae (Hemiptera: Aphididae) with 34% prevalence. This single-stranded DNA virus has a 5480-nucleotide ambisense genome and belongs to the Densovirinae subfamily within the family Parvoviridae. In the present study ... more

Genetic diversity; ISSR; Limnonectes gyldenstolpei; Limnonectes taylori; Parapatric

Biodiversity stems from speciation, and species identification allows scientists to measure species biodiversity. However, some closely related species, particularly amphibians that choose to inhabit the same environment, are difficult to identify. Juvenile specimens of Limnonectes gyldenstolpei (Lg) and L. taylori (Lt) were used as models to study the speciation ... more

The common bacterial blight, caused by Xanthomonas axonopodis pv. phaseoli (Xap) and X. fuscans subsp. fuscans (Xff), is one of the most important dry bean diseases of bacterial etiology. The present work aimed to study the genetic structure among and within populations, and also identify the pathogenic variability of Xap and Xff isolates evaluating the horizontal ... more

Lung cancer is the leading cause of cancer-related deaths worldwide. Despite therapeutic advances over the last several decades, the overall 5-year survival remains only 16%. (Siegel R, 2013). Molecular studies have indicated that Adenocarcinomas have distinct genomic alterations allowing classification into clinically relevant molecular subsets. Such specific ... more

Copernicia prunifera; Genetic diversity; ISSR; Stepwise multiple regression analysis

The carnauba palm Copernicia prunifera is the third most important non-timber forest species in Brazil; it is mainly known for the production of carnauba wax. We examined intra-population genetic diversity and correlated genotypic and phenotypic traits of 28 trees from a coastal location in Rio Grande do Norte state. Phenotypic variables tree height, ... more

Genetic diversity; Germplasm collection; Molecular markers; Vigna unguiculata

The cowpea, Vigna unguiculata (Fabeaceae) is widely cultivated in semi-arid regions, such as northeast Brazil. Due to the low crop yields in this region, it would be useful to develop cultivars adapted to these climate conditions. Landraces are seen as an important source of germplasm to be used in breeding programs of this species due to their good adaptation to the environment, but ... more

Black rhinoceros; D-loop; Genetic diversity; Kenya; Mitochondrial DNA; Translocations

The black rhino sanctuaries system has played a key role in repopulating and starting new subpopulations in Kenya. If this system is efficiently managed it may save the black rhinoceros from local extinction. Understanding the genetic status of endangered species is the most elemental sine qua non of animal breeding and conservation. It is therefore ... more
