Identification of midvein and edge DE-genes in a lateral 1D leaf cross-section: a DE-gene analysis of a 1D A. thaliana leaf lateral cross sections by comparing the midvein (square-5) or the margin squares (square-1 and square-8) with the ‘bulk’ (remaining) leaf sections. The two images in b show 393 DE-genes with higher (left, 256 DE genes) or lower (right, 137 DE genes) expression values in the midvein. The images in c show 686 DE-genes higher (left, 403 DE genes) or lower (right, 283 DE genes) expression in the leaf margins. The grey dashed line in each plot (b and c) represents a trend-line for the average log₂ (normalised counts) of all genes normalised across the leaf squares
