Cultivated strawberry emerged from the hybridization of two wild octoploid species, both
descendants from the merger of four diploid progenitor species into a single nucleus more …

Plant genomes are often characterized by a high level of repetitiveness and polyploid
nature. Consequently, creating genome assemblies for plant genomes is challenging. The …

Common oat (Avena sativa) is an important cereal crop serving as a valuable source of
