Leaf Trait Evolution in Mexican Viburnum.

The genus Viburnum exhibits great variation in leaf traits such as size, shape, trichome density, and marginal teeth. We are focusing on replicated evolution of leaf traits in the Viburnum of Mexico as a system for studying broader trends in leaf trait evolution across the group. Here we examine leaf trait evolutionary dynamics across the Viburnum of Mexico and more specifically within hybrid swarms where two sister species with different leaf types hybridize to yield a mix of intermediate leaf phenotypes suitable for association mapping. We leverage the genotypic diversity in the hybrids and between parental populations to better understand the genetic mechanisms underlying leaf trait diversification.
