Current Research ProjectsMy research lab is working to elucidate the cytological and genetic mechanisms controlling early endosperm development in maize kernels. Maize kernels are a major food source and industrial commodity for the starch housed in the endosperm tissue. Our work uses microscopy and growth analysis to describe the formative events in endosperm tissue development within the kernel. During this work we discovered and named a new cell type and are currently extending our light microscopic descriptions of these cells using transmission electron microscopy to describe their ultrastructure. Through a large scale sequencing effort of these earliest developmental stages, we described what genes are expressed and how gene expression changes during development. We are building upon this work to tie gene regulatory networks to developmental events and specific cell types. In addition, we are taking a comparative approach to study how endosperm development in the reference genetic line of maize compares with other lines with large and small mature kernels to help understand the determinants that produce large kernels with abundant starch. Lastly, we are currently examining the effects of drought stress on early endosperm and kernel development.
