The number of genes that are differentially expressed between two tissues can be obtained from the table below. For instance, in the upper left hand corner when comparing young leaf and flower there are 10,262 genes that have a higher gene expression in flower than in young leaf and 7,298 genes that have a higher gene expression in young leaf than in flower. As you can see the table is not symmetric. Think of the upper triangle as the genes that show a significant increase in gene expression between two tissues and the lower triangle as the genes that show a significant decrease in gene expression between the same two tissues. This is the same as saying for each cell the tissues across the bottom will have this many genes that have a significant increase in gene expression than the tissues on the left. The table below is color coded from white to green to purple based on the number of genes in each cell. Clicking on the cell will result in a downloadable list of genes for further exploration. One application of this table is to explore the differential gene expression between two developmental time points in a tissue of interest to gain insight into the gene functions and thereby the biological processes that occur during particular stages of development.
