Genome merger: from sequence rearrangements in triticale to their elimination i...
Silva, Manuela; Viegas, Wanda; Bento, Miguel; Gustafson, PerryAbstract 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 uses inter-retrotransposon amplified polymorphisms (IRAP) and retrotransposon microsatellite amplified polymorphisms...
Polyploidization as a retraction force in plant genome evolution: sequence rear...
Silva, Manuela; Viegas, Wanda; Bento, Miguel; Pereira, H. Sofia; Rocheta, Margarida; Gustafson, PerryBackground. 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 sequences involved are still sparse. Methodology/Principal Findings. Inter Retrotransposons Amplified Polymorphis...
