Venn diagrams of comparisons between UV-B-responsive genes in different tissues of maize. Upregulated genes are colored red, downregulated genes are colored green. Sets of genes were selected using the criteria described in Materials and methods. (a) Intersection of genes regulated by UV-B in UV-B-exposed tissues (seedling and adult leaves and emerging tassels). (b) Intersection of genes regulated by UV-B in UV-B shielded tissues (roots and immature ears) and seedling leaves.
