Somatic genome-doubling is the most parsimonious route to allopolyploidy.

The New phytologist - 1 Jun 2026

Burns Robin, Scott Alison Dawn, Novikova Polina Yu

Abstract excerpt

The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome-doubling and re-writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable. For sterile hybrids, somatic genome-doubling can be an immediate...
