Formation of viable pollens is essential for sexual reproduction of flowering plants, and vital to grain production in agriculture. During pollen formation, a callose wall is built on the pollen mother cells and microspore tetrads. The callose wall is degraded by beta-1, 3-glucanase (callase) secreted by the tapetum cells, leading to the release of microspores in the locular space of developing anthers. Screens of Arabidopsis mutants defective in the callose wall have identified a group of genes required for the formation of viable pollens. Research in my laboratory focuses on the characterization of callose synthases that are responsible for the synthesis of callose during pollen development. We have also been characterizing genes that are responsible for grain development in wheat, barley and rice. The experimental approach taken in my laboratory includes biochemistry, molecular biology, cell and developmental biology, genetics, genomics and proteomics.
