Research Abstract

Here I investigated the molecular diversity of LURE, which is important for pollen tube guidance in Torenia. LURE1 althologues were conserved in the Torenia species, but its protein sequences were diverged. LURE1 proteins attracted pollen tubes in a species-specific manner, suggesting that the diversification of pollen tube guidance molecules is one of the mechanism to prevent interspecific crosses.
