Changes in flower phenotype within a plant lineage may provide strong evidence of adaptive divergence mediated by different pollinator agents. We tested this hypothesis in Salpi chroa Miers. This genus\, mainly distributed above 2000 m in the Andes of S outh America\, comprises 22 shrubby or scandent species showing remarkable floral phenotype variation. We asked whether the inter-specific floral vari ation was associated with changes in pollination mode. We identified pollin ators in natural populations\, quantified floral traits relevant to pollina tion (color as perceived by pollinators\, morphology\, size\, fragrance\, a nd nectar)\, undertook phylogenetic analyses and molecular dating\, perform ed ancestral reconstructions and comparative analyses. Our results suggest that changes in pollination mode played a major\, though not exclusive role \, in the remarkable floral diversification of the genus Salpichroa. \n\n \ n\nHost: Dr. John Schenk DTEND:20230407T165000Z DTSTAMP:20241127T054013Z DTSTART:20230407T155000Z GEO:39.324787;-82.103474 LOCATION:Porter Hall\, 104 SEQUENCE:0 SUMMARY:Plant Biology Colloquium | The evolution of flower traits in Salpic hroa (Solanaceae) and its relationship with contrasting pollination modes\, April 7 UID:tag:localist.com\,2008:EventInstance_42385186223535 URL:https://calendar.ohio.edu/event/plant_biology_colloquium_april_7_2023 END:VEVENT END:VCALENDAR
