CCR2 and hyperinsulinemic hypoglycemia, familial, 4: Twelve cDNA libraries, including three biological replicates for normal nitrogen (CK) leaf (CKL1, CKL2 and CKL3), N-deficiency leaf (NNL1, NNL2 and NNL3), normal nitrogen (CK) root (CKR1, CKR2 and CKR3), N-deficiency root (NNR1, NNR2 and NNR3) were constructed and sequenced.
