Reciprocal exchange of eukaryotic genetic material during meiotic crossing over is a major
source of genetic variation in sexually reproducing species. Crossover events are not …

Defining syntenic relationships among orthologous gene clusters is a frequent undertaking
of biologists studying organismal evolution through comparative genomic approaches. With …

Homologous genes, including paralogs and orthologs, are genes that share sequence
homologies within or between different species. Homologous genes originate from a …

A detailed comparative map of Brassica oleracea and Arabidopsis thaliana has been
established based largely on mapping of Arabidopsis ESTs in two Arabidopsis and four …

Comparative cytogenetic mapping is a powerful approach to gain insights into genome
organization of orphan crops, lacking a whole sequenced genome. To investigate the …

Background It is difficult to accurately interpret chromosomal correspondences such as true
orthology and paralogy due to significant divergence of genomes from a common ancestor …

Distribution of meiotic recombination events in plants has been associated with local
chromatin and DNA characteristics, chromosome landmark proximity, and other features …

The identification of causal genomic loci and their interactions underlying various traits in
plants has been greatly aided by progress in understanding the organization of the nuclear …

Background Extant genomes share regions where genes have the same order and
orientation, which are thought to arise from the conservation of an ancestral order of genes …

In most eukaryotic species, three basic steps of pairing, recombination and synapsis occur
during prophase of meiosis I. Homologous chromosomal pairing and recombination are …
