From: Genome-wide expression profiling of leaves and roots of watermelon in response to low nitrogen
Venn diagrams presenting differential gene expression in the leaf and root of watermelon (a, b) grown under hydroponic conditions at 0.2 mM and 9 mM N. LHN: leaf high N (9 mM); LLN: leaf low N (0.2 mM); RHN: root high N (9 mM); RLN: roots low N (0.2 mM). The leaf and root samples of watermelon for transcriptome analysis were harvested at day 14 after N treatment
