Chromosome Number Variation in Iranian Populations of Acorus calamus
Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...
متن کاملHigh and uneven levels of 45S rDNA site-number variation across wild populations of a diploid plant genus (Anacyclus, Asteraceae)
The nuclear genome harbours hundreds to several thousand copies of ribosomal DNA. Despite their essential role in cellular ribogenesis few studies have addressed intrapopulation, interpopulation and interspecific levels of rDNA variability in wild plants. Some studies have assessed the extent of rDNA variation at the sequence and copy-number level with large sampling in several species. However...
متن کاملThe Number of Cultural Traits Is Correlated with Female Group Size but Not with Male Group Size in Chimpanzee Communities
What determines the number of cultural traits present in chimpanzee (Pan troglodytes) communities is poorly understood. In humans, theoretical models suggest that the frequency of cultural traits can be predicted by population size. In chimpanzees, however, females seem to have a particularly important role as cultural carriers. Female chimpanzees use tools more frequently than males. They also...
متن کاملTelomere length is correlated with mitochondrial DNA copy number in intestinal, but not diffuse, gastric cancer.
A positive correlation between telomere length and mitochondrial DNA (mtDNA) copy number has previously been observed in healthy individuals, and in patients with psychiatric disorders. In the present study, telomere length and mtDNA copy number were evaluated in gastric cancer (GC) tissue samples. DNA was extracted from 109 GC samples (including 82 intestinal, and 27 diffuse cases), and the te...
متن کاملDHPLC Applications: Finding DNA Variation on the Y Chromosome
Denaturing High-Performance Liquid Chromatography (DHPLC) is a recently developed technique forthe detection of single nucleotide polymorphisms (SNPs) and mutations. It involves the comparisonbetween two or more DNAs as a mixture of denatured and reannealed PCR products. The methodologyis based on the principle of reversed phase liquid chromatography and uses a unique DNA sepa...
