Annotation:
Our review targets interspecific hybridization, one of the main mechanisms of plant speciation. Genomes of newly established interspecific hybrids undergo dramatic changes including chromosome rearrangements, amplifications of tandem repeats, activations of mobile repetitive elements and gene expression modifications. To ensure genome stability and proper transmission of chromosomes from both parental genomes into subsequent generations, allopolyploids often evolve mechanisms regulating chromosome pairing.
