Maize grown under normal field conditions vs under 60% shade or under 2X density

These experiments were to investigate changes in gene expression associated with maize competition for light when grown at double normal population density or under 60% shaded conditions as opposed to when maize is grown under normal field conditions. Three biological replicates (collected from separate field plots) comprised of pooled samples of 4 plants from each treatment were hybridized in a rolling circle dye swap hybridization screen.
