  • A1, A2, A3, B1, B2, B3, C1, and C2 designate the same group categories described in Figure 3 and Supplemental Data Set 2 online. Footnotes indicate exceptions.

  • a Some transcripts were more abundant in snrk2.1 mutant relative to wild-type cells in +S conditions.

  • b Some transcripts were also diminished in snrk2.1 mutant cells.

  • c Some transcripts were not diminished in snrk2.1 mutant cells.
