Figure 1.
Ven diagram of differentially expressed genes in different parts of wheat grain endosperm under high and low nitrogen treatments. HN-IE and HN-RE are samples from innermost endosperm region and the remaining endosperm region under high nitrogen treatment, respectively. LN-IE and LN-RE are samples from innermost endosperm region and the remaining endosperm region under low nitrogen treatment, respectively. The number outside (inside) brackets stand for up-regulation (down-regulation) differentially expressed genes.
