摘要：

Genome duplication is potentially a good source of new genes, but such genes take time to evolve. We have found a group of 'duplication-resistant' genes, which have undergone convergent restoration to singleton status following several independent genome duplications. Restoration of duplication-resistant genes to singleton status could be important to long-term survival of a polyploid lineage. Angiosperms show more frequent polyploidization and a higher degree of duplicate gene preservation than other paleopolyploids, making them well-suited to further study of duplication-resistant genes.
