Freshwater fish; Genetic diversity; Mantel test; Microsatellite; Population genetic structure; Spatial autocorrelation

Geographical genetics allows the evaluation of evolutionary processes underlying genetic variation within and among local populations and forms the basis for establishing more effective strategies for biodiversity conservation at the population level. In this study, we used explicit spatial analyses to investigate molecular genetic variation (estimated using 7 microsatellite markers) of ... more

Carpogenic germination; Microsatellite; Morphology characterization; Mycelial compatibility group; Sclerotinia sclerotiorum

White mold is a common bean disease caused by the fungus Sclerotinia sclerotiorum, resulting in economic losses in Brazil and worldwide. Lack of knowledge about the population structure of the pathogen makes it difficult to control the disease. The aim of this study was to characterize strains of S. sclerotiorum obtained from ex­perimental and commercial common bean ... more

Conservation; Holothuria scabra; Microsatellite; Sea cucumber

The sea cucumber Holothuria scabra is an endangered species. In this study, nine new polymorphic microsatellite loci were developed and tested in 30 individuals. The number of alleles ranged from 2 to 5, and the observed and expected heterozygosities ranged from 0.1200 to 0.7391 and from 0.2408 to 0.5983, respectively. No loci significantly deviated from the Hardy-Weinberg ... more

Microsatellite; Odontobutis potamophila; Polymorphism

We characterized 16 novel polymorphic loci isolated from a partial genomic DNA library of Odontobutis potamophila enriched for CA repeats. We tested the variability of these microsatellites on 51 unrelated individuals collected in China. All loci were polymorphic. The average allele number was 14.6 per locus, ranging from 2 to 27. The observed heterozygosity ranged from 0.35 to ... more

Meretrix meretrix is one of the important commercial bivalves in China. A total of 198 individual clams were collected from 5 locations characteristic of the clam’s 5 main natural habitats in China, that is, Shandong, Jiangsu, Fujian, Guangdong, and Guangxi. Ten polymorphic microsatellite markers were selected to examine the genetic diversity and identify genetic differences ... more

Conservation resources; Genetic markers; Microsatellite; Sebastiscus marmoratus

The marbled rockfish, Sebastiscus marmoratus, is an important commercially near-shore fish that inhabits the beach rocky bottom from Japan to the South China Sea. Eleven polymorphic microsatellite loci were developed from S. marmoratus and were used to identify polymorphisms in 30 samples from a wild population. The allele locus number ranged from 2 to 7. Polymorphism ... more

Germplasm conservation; Holothuria leucospilota; Microsatellite; Sea cucumber

Holothuria leucospilota is a tropical holothurian species that is widely distributed in the tropical and sub-tropical India-Western Pacific Region. Eight polymorphic microsatellite loci were developed from H. leucospilota by using the protocol fast isolation by amplified fragment length polymorphism of sequences containing repeats and tested in 30 individuals from Hainan ... more

Comet assay; Medicinal plant; Micronucleus test; Single-cell gel electrophoresis; Tamarindus indica

Tamarindus indica has been used in folk medicine as an antidiabetic, a digestive aid, and a carminative, among other uses. Currently, there is no information in the toxicology literature concerning the safety of T. indica extract. We evaluated the clastogenic and/or genotoxic potential of fruit pulp extract of this plant in vivo in peripheral blood and liver ... more

Bignoniaceae; Medicinal plant; Preservation; Random amplified polymorphic DNA

Catuaba (Anemopaegma arvense), a Bignoniaceae species endemic to Cerrado regions, shows anticancer properties and is widely used as a stimulant in traditional medicine. We evaluated the genetic diversity of seven populations found in the State of São Paulo, using random amplified polymorphic DNA markers. After optimization of the amplification reaction, 10 selected primers produced 70 ... more

Colombia; Genetic structure; Isoenzymes; Population genetics; Psorophora columbiae; Psorophora toltecum

Two populations of the mosquito Psorophora columbiae from the central Andean area of Colombia and one population of Ps. toltecum from the Atlantic coast of Colombia were analyzed for 11 isoenzyme markers. Psorophora columbiae and Ps. toltecum are two of the main vectors of Venezuelan equine encephalitis. We found no conspicuous genetic differences between the two ... more
