Summary of the six root-hypocotyl gene sets organized by functional category

Within each tissue-biased gene set, the percentage of genes in each functional category is shown followed by the number (in parentheses) of genes in each category. The single highest-ranking category (for xylem/phloem-cambium and xylem/nonvascular) or two highest-ranking categories (for xylem, phloem-cambium, nonvascular, and phloem-cambium/nonvascular) for each gene set, from among the classified genes, are shown in bold.
