Population genomics of the Isoetes appalachiana (Isoetaceae) complex supports a 'diploids-first' approach to conservation.

ABSTRACT:

Background and aims

Allopolyploidy is an important driver of diversification and a key contributor to genetic novelty across the tree of life. However, many studies have questioned the importance of extant polyploid lineages, suggesting that the vast majority may constitute evolutionary 'dead ends'. This has important implications for conservation efforts where polyploids and diploid progenitors often compete for wildlife management resources. Isoetes appalachiana is an allotetraploid that is broadly distributed throughout the eastern USA alongside its diploid progenitors, I. valida and I. engelmannii. As such, this species complex provides an excellent opportunity to investigate the processes that underpin the formation and survival of allopolyploid lineages.
