A rapid and reliable PCR-restriction fragment length polymorphism (RFLP) marker was developed to identify the Amaranthus cruentus species by comparing sequences of the starch branching enzyme (SBE) locus among the three cultivated grain amaranths. We determined the partial SBE genomic sequence in 72 accessions collected from diverse locations around the world by direct sequence analysis. Then, ...

Background: The worldwide distribution of P. vivax has expanded significantly and the number of reported cases has been on the rise. Approximately 88% of malaria cases in Iran are caused by Plasmodium vivax, and in order to management of the disease, understanding the population genetic structure of the parasite is necessary for designing and applying drugs and vaccines. Among many potential ca...

Abstract. Aguilar KEV, Vivas AYS, Acosta-López C. 2023. Genetic variation of Limnophora marginata Stein, 1904 (Diptera: Muscidae), associated with an altitudinal gradient in Pedro Moncayo Canton, Pichincha, Ecuador. Biodiversitas 24: 269-275. Analyzing heterogeneity insect populations is relevant to understanding its biology. Thus, we analyzed the genetic variability two “hunter-flies”, Tocachi...

Molecular markers and mapping are used to analyze an organism’s genes. They allow the selection of target genetic areas based on marker genotype (and not trait phenotype), facilitate study variability diversity, create linkage maps, follow individuals or lines carrying certain may be select parental genotypes, remove drag in back-crossing, choose difficult-to-measure characteristics. Due a lack...

Background: Toxoplasmosis is one of the most important food-borne diseases distributed worldwide. In order to determinate the involvement of poultry meat in clinical toxoplasmosis, this study aimed to genetic characterization of Toxoplasma gondii in tissue samples of serologically positive chickens of Tunisia using Polymerase Chain Reaction (PCR). Methods: Trail of isolation of local T. gondii...

The identification of molecular markers linked to leaf curl virus (CLCuV) disease resistance in cotton has the potential to improve both the efficiency and the efficacy of selection in cotton breeding programs. Genetic analysis suggested that CLCuV resistance is controlled by a single dominant gene. In this study, an interspecific F2 population derived from a cross of Gossypium barbadense and G...

POU1F1 is a positive regulator for GH, PRL and TSHβ and its mutations associate with production traits in ruminant animals. We described a DdeI PCR-RFLP method for detecting a silent allele in the goat POU1F1 gene: TCT (241Ser)>TCG (241Ser). Frequencies of D1 allele varied from 0.600 to 1.000 in Chinese 801 goats. Significant associations of DdeI polymorphism with production traits were found i...
