(a) The differentially expressed flowering-related genes in GsWRKY20ox plants. Genes which were up or down-regulated (>2-fold) in the GsWRKY20ox plants compared with the WT are listed. The P values were corrected for multiple testing using FDR methodology. The group of genes was classified based on their biochemical functions. AGI, Arabidopsis Genome Initiative number; FC, fold changes.
(b) Expression validation of the differentially expressed flowering-related genes. Total RNAs were extracted from three-week-old whole plants grown on 0.5 × MS-agar. Transcript levels relative to ACTIN2 are presented for each treatment. Each value is the mean ±SE of three independent measurements. Significant differences from WT are denoted by one, or two stars corresponding to P < 0.05, and P < 0.01, respectively by Student’s t test.
