Polyploidy has been hypothesized to be both an evolutionary dead-end and a source for
evolutionary innovation and species diversification. Although polyploid organisms …

Cultivated oat (Avena sativa L.) is an allohexaploid (AACCDD, 2 n= 6 x= 42) thought to have
been domesticated more than 3,000 years ago while growing as a weed in wheat, emmer …

Cultivated rice varieties are all diploid, and polyploidization of rice has long been desired
because of its advantages in genome buffering, vigorousness, and environmental …

Evidence of whole-genome duplications (WGDs) and subsequent karyotype changes has
been detected in most major lineages of living organisms on Earth. To clarify the complex …

Domestication of the apple was mainly driven by interspecific hybridization. In the present
study, we report the haplotype-resolved genomes of the cultivated apple (Malus domestica …

INTRODUCTION Polyploidy, arising from whole-genome duplication or interspecific
hybridization, is ubiquitous across the plant and fungal kingdoms. The presence of highly …

Green plants play a fundamental role in ecosystems, human health, and agriculture. As de
novo genomes are being generated for all known eukaryotic species as advocated by the …

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 …
