Doubling down on polyploid discoveries: Global advances in genomics and ecological impacts of polyploidy

MS Barker, Y Jiao, KL Glennon - American Journal of Botany, 2024 - Wiley Online Library
All flowering plants are now recognized as diploidized paleopolyploids (Jiao et al., 2011;
One Thousand Plant Transcriptomes Initiative, 2019), and polyploid species comprise …

A comprehensive examination of Chelicerate genomes reveals no evidence for a whole genome duplication among spiders and scorpions

GWC Thomas, MTW McKibben, MW Hahn, MS Barker - bioRxiv, 2024 - biorxiv.org
Whole genome duplications (WGDs) can be a key event in evolution, playing a role in both
adaptation and speciation. While WGDs are common throughout the history of plants, only a …

Ancient polyploidy and low rate of chromosome loss explain the high chromosome numbers of homosporous ferns

Z Li, SP Kinosian, S Zhan, MS Barker - bioRxiv, 2024 - biorxiv.org
A longstanding question in plant evolution is why ferns have many more chromosomes than
angiosperms. The leading hypothesis proposes that ferns have ancient polyploidy without …
