摘要
The evolutionary fate of polyploids (especially plants) immediately following their formation has recently received renewed attention by several research groups. An increasing body of work demonstrates that genome rearrangements, epigenetic alterations, and changed gene expression levels often accompany polyploidization. New data indicate that altered gene expression patterns can occur in polyploids with few signs of genome reorganization, suggesting a mechanism involving interactions of diverged regulatory hierarchies.
