Genetic Variability
Differential responses of one hundred tomato genotypes grown under cadmium stress
Authors: M.M. Hussain, A. Saeed, A.A. Khan, S. Javid and B. Fatima
Due to increased global concern over the deleterious effects of toxic heavy metals in the environment, it has become necessary to develop plant genotypes that limit the uptake of heavy metals to aerial edible parts. To address this concern, we performed a glasshouse experiment to assess variations within tomato germplasm for cadmium (Cd) tolerance under c.. Read More»

Molecular marker-based genetic diversity analysis of scantly studied Brazilian accessions of a medicinal plant, Morinda citrifolia L. (noni)
Authors: P.N. Bordallo, A.M.R. Monteiro, J.A. Sousa and F.A.S. Arag�£o
Morinda citrifolia L., commonly known as noni, has been used for the treatment of various diseases for over two centuries. It was introduced and widely disseminated in Brazil because of its high market value and ease of adaptation to the soil and climatic conditions of the country. The aim of this study was to estimate the gen.. Read More»

Contribution of microsatellites markers in the clarification of the origin, genetic risk factors, and implications for conservation of Tunisian native sheep breeds
Authors: Y. Ben Sassi-Zaidy F. Maretto F. Charfi-Cheikhrouha A. Mohamed-Brahmi M. Cassandro
The genetic diversity and genetic relationship of the two main groups of African sheep, thin-tailed and fat-tailed sheep, represented by the indigenous Tunisian sheep breeds “Barbarine” (BAR, fat-tailed) and “Queue Fine de l’Ouest” (QFO, thin-tailed) were investigated. The genotypes of 110 animals belonging to these two breed.. Read More»

Genetic variability and heterogeneity of Venezuelan equine encephalitis virus vector Ochlerotatus taeniorhynchus (Diptera: Culicidae) populations of the Colombian Atlantic coast, based on microsatellite loci
Authors: F. Bello and V. Becerra
In Colombia, the mosquito Ochlerotatus taeniorhynchus has been identified as an efficient vector of the epidemic-epizootic Venezuelan equine encephalitis virus. We evaluated the genetic variability and heterogeneity of this mosquito in Colombian populations using eight microsatellite DNA loci. Two hundred and te.. Read More»

Population genetic structure in Phyla scaberrima from Mexico and Colombia assessed by AFLP markers and implications for conservation
Authors: L.G. Androcioli, E.A. Ruas, L.A. Rodrigues, C.F. Ruas , H.E.R. Perilla, P.M. Ruas
Phyla scaberrima (Verbenaceae) is a herbaceous perennial species that is distributed from Mexico (center of origin) to Colombia, growing in forest and swamp edges or grasslands from sea level up to an altitude of 1800 m. The chemical properties and uses in popular medicine have drastically affected the population siz.. Read More»

Genetic diversity and differentiation in natural populations of Arapaima gigas from lower Amazon revealed by microsatellites
Authors: P.F. Fazzi-Gomes, N. Melo, G. Palheta, S. Guerreiro, M. Amador, A.K. Ribeiro-dos-Santos, S. Santos and I. Hamoy
Genetic variability is one of the important criteria for species conservation decisions. This study aimed to analyze the genetic diversity and the population differentiation of two natural populations of Arapaima gigas, a species with a long history of being commercially exploited. We collected 87 samples of A. gigas from Gran.. Read More»

Genetic variability of CYP3A4 in a heterogeneous Brazilian population from Maranh�£o

Inter-individual variability in drug metabolism may result in adverse drug responses. Pharmacogenetic studies have shown that polymorphisms in drug metabolizing enzymes may contribute to this variability. Among these enzymes, CYP3A4 is responsible for metabolizing over 50% of the clinically used drugs. The Brazilian population is composed of people with N.. Read More»

Insulin secretion is regulated by ATP-sensitive potassium channels (KATP). The potassium inwardly-rectifying channel, subfamily J, member 11 (KCNJ11) gene, located on chromosome 11p15.1, encodes the subunit Kir6.2 that forms the pore region of KATP channels in pancreatic β-cells. Among the single nucleotide polymorphisms .. Read More»
