Patterns of genetic variation in a prairie wildflower, Silphium integrifolium, suggest a non-prairie origin and locally adaptive variation.

This study uses population genetic data to show Silphium integrifolium originated outside modern prairies and identifies loci linked to local adaptation, suggesting broader germplasm collection could improve breeding programs.

Spring flowering habit in field pennycress (Thlaspi arvense) has arisen multiple independent times

The paper identifies loss-of-function mutations in TaFLC that confer a spring annual phenotype in pennycress and shows the trait has evolved independently multiple times.
