| Research Abstract |
This study aimed to reveal the molecular mechanisms of self-incompatibility in the Brassicaceae and the Solanaceae. In the Brassicaceae, we have analyzed the downstream signaling cascades after the perception of the pollen determinant(SP11 ligand) by the pistil determinant(SRK receptor kinase), and identified some candidate molecules and some mutants related to the cascades. In the Solanaceae, we have revealed that the pollen determinant comprises multiple types of F-box proteins(SLFs), and proposed the "collaborative non-self recognition model" suggesting that SLFs collectively recognize and detoxify entire suite of non-self S-RNases.
