چکیده

Single Nucelotide Polymorphisms (SNPs) have become the most widely used markers in many current genetic applications. Here we report the discovery of nine new SNPs in olives by direct partial sequencing of two genes (OEX and OEW) in sixteen Tunisian cultivars. The SNP markers were then used to genotype 24 olive cultivars and assess the level of genetic diversity. Power of discrimination of SNP markers was then compared to that of microsatellites (SSRs). A combination of SSR and SNP markers was finally proposed that can be used for cultivars identification in juvenile step or for oil traceability.

Citrus (Rutaceae) SNP markers based on Competitive Allele-Specific PCR; transferability across the Aurantioideae subfamily1

UNLABELLED PREMISE OF THE STUDY Single nucleotide polymorphism (SNP) markers based on Competitive Allele-Specific PCR (KASPar) were developed from sequences of three Citrus species. Their transferability was tested in 63 Citrus genotypes and 19 relative genera of the subfamily Aurantioideae to estimate the potential of SNP markers, selected from a limited intrageneric discovery panel, for on...

SNP Discovery by Illumina-Based Transcriptome Sequencing of the Olive and the Genetic Characterization of Turkish Olive Genotypes Revealed by AFLP, SSR and SNP Markers

BACKGROUND The olive tree (Olea europaea L.) is a diploid (2n = 2x = 46) outcrossing species mainly grown in the Mediterranean area, where it is the most important oil-producing crop. Because of its economic, cultural and ecological importance, various DNA markers have been used in the olive to characterize and elucidate homonyms, synonyms and unknown accessions. However, a comprehensive charac...

Molecular Characterization of Unknown Potentially Salt Tolerant Olive Genotypes Using RAPD Markers

Randomly amplified polymorphic DNA (RAPD) markers were used to study the genetic diversity and discriminate among 17 unknown genotypes (considered potentially salt tolerant) and 16 known olive cultivars. Fifteen decamer primers which produced 38 reproducible polymorphic bands in the genotypes were selected for analysis. The RAPD markers resulted in 93 distinct banding patterns. Based on either ...

Digestive alkaline proteases from the Tunisian barbell (Barbus callensis): Characterization and application as a detergent additive, in chicken feather-degradation and as a dehairing agent

Alkaline crude enzymes from the viscera of the Tunisian barbel (Barbus callensis) were extracted and characterized. Proteolytic crude extract from barbel viscera was active and stable in alkaline solution. The optimum pH and temperature were 11.0 and 55 °C, respectively, using casein as a substrate. The crude alkaline protease was extremely stable in the pH range of 5.0-12.0. Zymography activit...
