Fig. 4

Gene ontology enrichment analysis (biological process: BP) of differential expressed proteins in response to ABA treatment. Blue bar indicates down regulation of biological processes at 2 h (a), 24 h (b), and 72 h post-treatment (c) respectively, whereas the orange bar indicates upregulation of biological process at 2 h (d), 24 h (e), and 72 h post-treatment (f) respectively. Only BP terms with a Benjamini-Hochberg corrected p-value of less than 0.05 were included.
