Heat maps for differential expression of genes for GA metabolism and signalling between watered and droughted wheat seedlings in the 4th leaf base and remaining leaf, and root tip and remaining root. For simplicity, the normalized reads for the homoeologues were combined and mean values for three biological replicates were calculated, as described in Methods. The number of normalized reads and LFCs for individual homoeologues together with the gene IDs are provided in Additional file 7. Grey boxes indicate that the number of summed reads are < 10 for the tissue section from both watered and droughted seedlings. Genes for which summed reads are < 10 in each tissue section are omitted. LB, leaf base; LR, remaining leaf; RT, root tip; RR, remaining root
