Usually in the context of seedling development we research the transport of ions including auxin, the functions of calcium-conducting glutamate receptors, and the functions of LAZY genes in sensing gravity. This work is done primarily with Arabidopsis thaliana. We also endeavor to make better measurements of plant structures and growth processes by analyzing automatically-acquired images with high throughput computing. Zea mays is the subject of much of this phenotype-measuring work.
