Genetic variation in natural populations

Marker development for the genetic study of natural variation in Arabidopsis thaliana

We report AtPRIMER, an application that automates the discovery of new polymorphic markers between ecotypes of Arabidopsis thaliana. On specifying two ecotypes and the genomic region of interest, the script retrieves all corresponding single nucleotide polymorphisms (SNPs) and generates CAPS and/or dCAPS PCR primer sequences. We show that AtPRIMER accurately found specific polymorphic markers f...

Genetic Variation Among Salvia Species Based on Sequence-Related Amplified Polymorphism (SRAP) Marker

In this study, SRAP molecular maker approach was performed to investigate genetic diversity in the Salvia genus. A total of 205 DNA bands were produced from PCR amplification of 11 Salvia species and populations using 25 selective primer combinations, of which 204 polymorphic genetic loci accounted. The total number of amplified fragments ranged from 3 to 15. The genetic similarities of 11 coll...

Genetic variation in senescence marker protein-30 is associated with natural variation in cold tolerance in Drosophila.

A comprehensive understanding of the genetic basis of phenotypic adaptation in nature requires the identification of the functional allelic variation underlying adaptive phenotypes. The manner in which organisms respond to temperature extremes is an adaptation in many species. In the current study, we investigate the role of molecular variation in senescence marker protein-30 (Smp-30) on natura...

Natural genetic variation for improving crop quality.

The narrow genetic basis of many crops combined with restrictions on the commercial use of genetically modified plants, has led to a surge of interest in exploring natural biodiversity as a source of novel alleles to improve the productivity, adaptation, quality and nutritional value of crops. Genetic methodologies have been applied to natural variation to improve quality aspects that are assoc...
