Estimating the rate of clonal reproduction in natural population of diploid organisms is recognised as being problematic and even the detection of strictly clonal populations is often controversial. One well-acknowledged signature of clonal reproduction is the generation of non-random associations between loci. Linkage disequilibrium (LD) is thus often used for estimating the amount of clonal r...

Polyploidy is often assumed to increase the spread and thus the success of alien plant species, but few empirical studies exist. We tested this hypothesis with Centaurea maculosa Lam., a species native to Europe and introduced into North America approximately 120 years ago where it became highly invasive. We analyzed the ploidy level of more than 2000 plants from 93 native and 48 invasive C. ma...

Background: Telomeric DNA is found at the end of eukaryotic chromosomes, where they play a role in protecting chromosome and integrity genome organism through activity telomerase. Saccharomyces cerevisiae exists two genotypes: haploid diploid. Temperature sensitive point mutation on cdc13 gene each genotype deletion exo1 (cdc13-1Exo1 mutants) give rise to mutant survivors enhanced temperatures...
