Flowering plant origins: Dosage-sensitive genes suggest no whole-genome duplications in ancestral angiosperm‎

Angiosperms, also known as flowering plants, represent the most diverse group of seed plants, and their origin and evolution have long been a central question in plant evolutionary biology. Whole-genome duplication (WGD), or polyploidization, is widely recognized as a key driver of the origin and trait evolution of both seed plants and angiosperms.
