I am interested in plant reproductive biology, particularly in the molecular mechanisms underlying pollen-pistil interactions. Flowering plants have evolved complex mechanisms not only to support pollination and fertilization success, but also to shape plant mating systems and determine species-specific interactions. I am interested in how these processes are mediated and how they are influenced by other internal and external cues.

research overview

  • In the Nasrallah laboratory, I am investigating the self-incompatibility (SI) response of the Brassicaceae, a mechanism by which stigma epidermal cells recognize and reject self-pollen. My research projects are aimed at dissecting SI signaling using transgenic self-incompatible Arabidopsis thaliana as a model system. Our studies have begun to unravel the complex genetic network of SI signaling. Insights into this genetic network will not only reveal the underlying molecular basis of SI signaling, but will also shed light on how SI is influenced by other genetic pathways.
