Table V. Comparisons with published microarray data

Synthesis of the number of genes in common between our microarray data and data obtained from 3 days N-starved seedlings (Scheible et al., 2004), the shoots of adults plants subjected to mild or severe N limitation (Bi et al., 2007), the roots and shoots of seedlings after 20 minutes of nitrate induction (Wang et al., 2003) and the roots of adult plants after 0.5, 1.5 and 8 h of nitrate induction (Patterson et al., 2010).
