Genome merger: from sequence rearrangements in triticale to their elimination in wheat-rye addition lines

Author(s) : Silva, Manuela , Viegas, Wanda , Bento, Miguel , Gustafson, Perry
Description : Abstract Genetic and epigenetic modifications resulting from different genomes adjusting to a common nuclear environment have been observed in polyploids. Sequence restructuring within genomes involving retrotransposon/ microsatellite-rich regions has been reported in triticale. The present study us...

Polyploidization as a retraction force in plant genome evolution: sequence rearrangements in triticale

Author(s) : Silva, Manuela , Viegas, Wanda , Bento, Miguel , Pereira, H. Sofia , Rocheta, Margarida , Gustafson, Perry
Description : Background. Polyploidization is a major evolutionary process in plants where hybridization and chromosome doubling induce enormous genomic stress and can generate genetic and epigenetic modifications. However, proper evaluation of DNA sequence restructuring events and the precise characterization of...

Involvement of disperse repetitive sequences in wheat/rye genome adjustment

Author(s) : Tomás, Diana , Bento, Miguel , Viegas, Wanda , Silva, Manuela
Description : The union of different genomes in the same nucleus frequently results in hybrid genotypes with improved genome plasticity related to both genome remodeling events and changes in gene expression. Most modern cereal crops are polyploid species. Triticale, synthesized by the cross between wheat and rye...
