Anatomy and development of fleshy fruits in the monocots.

Though fruits in the monocot clade are predominantly capsular, baccate fruits are present in several distantly related monocot orders and families. Capsules are generally accepted as the ancestral fruit type for the monocots, and the presence of baccate fruits in various unrelated monocot groups is considered the result of convergent evolution. The independent evolution of fleshy fruits multiple times in the monocot clade implies that separate lineages of baccate fruits may have varying developmental pathways. However, information on the ontogeny and anatomy of monocot fruits is scarce. In a recent study by Rassmusen et al. (2006), capsular and baccate fruits from the Asparagales were examined to determine the evolution of fruit type in the order. This study aims to expand upon that of Rassmusen et al. by examining the anatomy and development of baccate fruits in select genera from the Commelinales, Dioscoreales, Liliales, and Poales in addition to the Asparagales in order to better understand the evolution of fruit types in the monocot clade on a larger scale.
