Changes in gene expression levels in tppf1 as assessed by RNA-seq. a Venn diagram showing overlapping differentially expressed gene (DEG) sets among OE9(DR)/WT(DR) up (OE9-drought vs. WT-drought; upregulated), OE9(DR)/WT(DR) down (OE9-drought vs. WT-drought; downregulated), WT(DR)/WT(CK) up (WT-drought vs. WT-well-watered; upregulated), and WT(DR)/WT(CK) down (WT-drought vs. WT-well-watered; downregulated). b Statistical analysis of upregulated and downregulated genes between OE9 and WT plants under well-watered [CK/CK (OE9/WT)] and drought conditions [DR/DR (OE9/WT)]. c Results of RT-qPCR analysis of related genes. Error bars indicate SEs (n = 4, four biological replicates). All values for WT and OE9 plants are statistically significantly different from each other (Student’s t test; p value < 0.05)
