Ulmus americana (Ulmaceae) is a polyploid complex.
PREMISE OF THE STUDY Exotic diseases are threatening many North American tree species, and management of diseases requires understanding the biology of the host as well as the pathogen. Ulmus americana is a widespread dominant tree of eastern North America that has been widely planted as an ornamental and shade tree. Populations of the species have suffered heavy mortality from Dutch elm diseas...
متن کاملGenotyping of Snps in a polyploid genome by pyrosequencing.
Single-nucleotide polymorphisms (SNPs) are the most frequent DNA sequence variations, and they have become increasingly popular markers for association studies. Allelic discrimination of the mostly binary SNPs has been reported for diploid species, mainly the human, but not for polyploid genomes such as the agriculturally important crops. In the present study, we analyzed the applicability of p...
متن کاملSequence-Based Mapping of the Polyploid Wheat Genome
The emergence of new sequencing technologies has provided fast and cost-efficient strategies for high-resolution mapping of complex genomes. Although these approaches hold great promise to accelerate genome analysis, their application in studying genetic variation in wheat has been hindered by the complexity of its polyploid genome. Here, we applied the next-generation sequencing of a wheat dou...
متن کاملIdentified Hybrid tRNA Structure Genes in Archaeal Genome
Background: In Archaea, previous studies have revealed the presence of multiple intron-containing tRNAs and split tRNAs. The full unexpurgated analysis of archaeal tRNA genes remains a challenging task in the field of bioinformatics, because of the presence of various types of hidden tRNA genes in archaea. Here, we suggested a computational method that searched for widely separ...
متن کاملGenome downsizing and karyotype constancy in diploid and polyploid congeners: a model of genome size variation
Evolutionary chromosome change involves significant variation in DNA amount in diploids and genome downsizing in polyploids. Genome size and karyotype parameters of Hippeastrum species with different ploidy level were analysed. In Hippeastrum, polyploid species show less DNA content per basic genome than diploid species. The rate of variation is lower at higher ploidy levels. All the species ha...
