Abstract: Reproductive success in flowering plants is dependent on proper development of floral structures that allow for a cascade of intercellular signaling mechanisms to occur during pollination. Intercellular communication between male and female tissues is critical for the recognition of compatible pollen at the stigma, the guidance of tip-growing pollen tubes to the ovules, and finally, the entry of the pollen tube into the female gametophyte and release of the sperm cells so that double fertilization can occur to produce viable seeds. The number of seeds produced by flowering plants depends not only on the number of ovules produced during flower development, but also on the quality of the ovules and their ability to participate in the double fertilization process. Current research in the Kessler Lab is aimed at identifying genetic factors that control both ovule initiation and development during Arabidopsis flower development and the signaling pathways that are involved in pollen tube reception by the female gametophyte.
