Resurrecting urban sunflowers: Phenotypic and molecular changes between antecedent and modern populations separated by 36 years.

Molecular ecology - 1 Oct 2023

Spear Marissa M, Levi Sophie J, Etterson Julie R, Gross Briana L

Abstract excerpt

Resurrection experiments provide a unique opportunity to evaluate phenotypic and molecular evolution in response to environmental challenges. To understand the evolution of urban populations of Helianthus annuus, we compared plants from 36-year-old antecedent seed collections to modern seed collections from the same area using molecular and quantitative genetic approaches. We found 200 differentially expressed...
