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 factor in the origin and evolution of traits in seed plants and angiosperms.
