Longitudinal Section of a Maize Kernel

Cereal grains provide most of our food either directly or indirectly as animal feeds. Grains vary in their size and nutritional quality, which is determined largely through the growth and development of the different cell types of the endosperm and embryo.  

We are studying how endosperm and embryo growth is coordinated as well as mechanisms of cellular differentiation during seed development.  My lab is focusing on mutations that are likely to disrupt normal cellular signaling during seed formation, and we are taking a genomics approach to identify the genes affected in these mutants.
