microMORPH 2012 Workshop
Micro-evo-devo: Flower Form and Function
Held at the Arnold Arbroretum of Harvard University
May 11-13, 2012


 

Abstract of Workshop:

Floral function is intimately related to floral morphology.  Evolutionary transitions among pollinators, mating systems (selfing vs. outcrossing), sexual systems (e.g., hermaphroditism vs. monoecy, dioecy), and fruit dispersal syndromes are associated with changes in morphology and the developmental processes that underlie floral structure.  The role of natural selection in these evolutionary transitions has been the focus of intensive research and there is a rich body of both theoretical and empirical literature on the microevolutionary diversification of floral function.  In contrast, knowledge of the associated morphological and underlying developmental genetic modifications that must be associated with key evolutionary transitions in floral function during population divergence and speciation is surprisingly sparse.  This workshop will bring together experts on the microevolution of pollination syndromes, phylogeneticists with expertise in comparative methodology, and molecular developmental biologists working on underlying causes of differential organ growth (and abortion), timing of floral developmental events, symmetry, and floral and fruit histological and cell biological properties.
