Solanaceae Source

A global taxonomic resource for the nightshade family

Next SolSeminar will be presented by Mario Vallejo-Marín on Evolution and functional significance of anther cones in buzz-pollinated Solanum

Abstract. In this talk Mario will present recent research conducted by himself and his colleagues on the functional significance of anther cones. Anther cones are formed when the stamens of buzz-pollinated plants (those that require bee vibrations to release pollen grains), are presented together in the centre of the flower forming a more or less cohesive reproductive structure. In some cases, anther cones are formed by anthers that are joined together via small trichomes or bio-adhesives. These “joined” anther cones have evolved independently across multiple plant families and have evolved at least four times in Solanaceae: in tomatoes and wild relatives, in S. dulcamara, in S. luridifuscescens and related species, and in some species of Lycianthes. Using laser vibrometry and simple floral manipulations in three species of Solanum, they experimentally assessed the consequences of “free” vs. “joined” anther cones for the transmission of bee-like vibrations and for pollen release. Mario will present some hypotheses for the adaptive significance of joined anther cones.
