Article Synopsis
- Whole-genome duplication (WGD) helps create new traits in plants, but it's hard for these polyploids to survive long-term because they generally need more energy and space than their diploid ancestors.
- Researchers created a model to see if larger plants (polyploids) could compete with their smaller ancestors (diploids) based on how they use energy from photosynthesis.
- The results showed that polyploids can succeed even if they aren't as efficient at using energy, especially when they form repeatedly and compete for nutrients. Small changes in how plants manage their energy can help polyploids thrive.

Hybridization blurs species boundaries and leads to intertwined lineages resulting in reticulate evolution. Polyploidy, the outcome of whole genome duplication (WGD), has more recently been implicated in promoting and facilitating hybridization between polyploid species, potentially leading to adaptive introgression. However, because polyploid lineages are usually ephemeral states in the evolutionary history of life it is unclear whether WGD-potentiated hybridization has any appreciable effect on their diploid counterparts.
