  • a q value of ≤0.05. No changes in mRNA abundance were supported by a q value of ≤0.05.

  • b q value of ≤1e−5.

  • c The 32 genes in this table showed a minimum fold change of 1.5 supported by a P value of less than 0.05 in either mRNA or protein. Numbers in bold indicate a change in expression supported by a P value of less than 0.05. +INF (positive infinity) is used to denote instances where the protein was detected solely in the nitrogen-limited treatment.
