Development and Structure Phillips, Heather [1], Landis, Jacob [2], Specht, Chelsea [3]. To Fuse or not to Fuse: Investigating the Evolution and Development of Floral Fusion in the Zingiberales. Throughout the evolution of the angiosperm flower, developmental innovations have enabled the modification or elaboration of novel floral organs enabling subsequent diversification and expansion into new niches, for example the formation of novel pollinator relationships. One such developmental innovation is the fusion of various floral organs to form complex structures. Multiple types of floral fusion exist; each type may be the result of different developmental processes and has likely evolved multiple times independently across the angiosperm tree of life. The development of fused organs is thought to be mediated by the NAM/CUC3 subfamily of NAC transcription factors, which mediate boundary formation during meristematic development. During this talk, I will overview the need for a combined approach to investigating floral fusion traits , and show how I plan to utilize the Zingiberales as a model lineage for investigating floral fusion. Furthermore, I will outline the three main aims of my project, designed to investigate (1) macroevolutionary trends in floral fusion related traits, (2) the evolution and expression of the NAM/CUC3 genes, and (3) functional analysis of these genes via CRISPR/Cas mediated transformations in collaboration with the plant transformation facility here at Cornell.
