Table 1. Abundance of PR1-coexpressed transcripts and key SA signaling-related transcripts in 4-week–old pp2a-b′γ and pp2a-b′ζ single mutants and pp2a-b′γζ double mutants relative to wild-type plants in microarray analysis.
Values are log2 (FC) and are the means of four independent biological replicates. Statistically significant values of log2 (FC) > 1 and q value of q < 0.05 are indicated in bold. Coexpression rank to PR1 (AT2G14610) is based on the Mutual Rank (MR, data platform Ath-m.c7-1; Obayashi et al., 2018), according to the Arabidopsis thaliana trans-factor and cis-element prediction database (ATTED-II) v9.2 (http://atted.jp). AGI, Arabidopsis genome initiative locus code.
