Functional enrichment (biological process) of HS-IR genes after 1st HS and 2nd HS. HS-IR events significantly induced and repressed (2-fold change) after 1st HS and 2nd HS were identified for GO analysis. Totals of 229 1st HS-induced, 1,003 1st HS-repressed, 174 2nd HS-induced, and 523 2nd HS-repressed IR genes were submitted to the functional enrichment tool for 206, 881, 169, and 492 unique genes with annotations, respectively. GO terms were included in the list if P < 1E-04.
