Columns two and three show the number of genes which are induced or repressed compared to the stem base before excision. For column four, stem base genes were defined as those showing expression values > 1000 in the stem base before excision and expression values < 100 in fully developed roots (Table S1b). For column 5, root genes are those with expression values > 1000 in fully developed roots and expression values < 100 in the stem base (Table S1c). A graphical presentation is shown in Supplemental Figure S1.
