Plant–soil microbe feedbacks depend on distance and ploidy in a mixed cytotype population of Larrea tridentata

Theory predicts that mixed ploidy populations should be short-lived due to strong fitness disadvantages for the rare ploidy. However, are common, suggesting costs ploidies counterbalanced by ecological benefits emerge when rare. We investigated whether differences in interactions with soil microbes help maintain a tetraploid-hexaploid population of Larrea tridentata (creosote bush) Sonoran Desert, California, United States, where prior work documented ploidy-specific root-associated microbes.

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

American Journal of Botany, Journal Year: 2024, Volume and Issue: 111(8)

Published: Aug. 1, 2024

Abstract All flowering plants are now recognized as diploidized paleopolyploids (Jiao et al., 2011; One Thousand Plant Transcriptomes Initiative, 2019), and polyploid species comprise approximately 30% of contemporary plant (Wood 2009; Barker 2016a). A major implication these discoveries is that, to appreciate the evolution diversity, we need understand fundamental biology polyploids diploidization. This broadly by our community there a continued, growing interest in polyploidy research topic. Over past 25 years, sequencing analysis genomes has revolutionized understanding importance speciation land plants.
