The role of PQ redox status in miRNA expression. a Scheme representing the action of DCMU and DBMIB in the photosynthetic electron transport chain. b Treatment with DCMU and DBMIB influences the maximum efficiency of PSII expressed as the Fv/Fm parameter. Plant material: dark—plants kept in darkness for 4 h; LLc—control plants in LL; LLtrt—plants treated with DCMU or DBMIB for 4 h and kept in LL. Asterisks indicate significant differences according to Tukey’s HSD test at the level of *** ≤ 0.001. Mean values ± SDs (n = 9) were provided. c qRT-PCR for pri-miR163 and pri-miR840 after using DCMU or DBMIB (upper panel). Transcript levels were normalized with respect to the PP2A and UPL7 genes. TT-qRT PCR for miR163 and miR840 after treatment with DCMU or DBMIB (bottom panel). Transcript levels were normalized with respect to sno85 and sno101. Asterisks indicate significant differences according to Tukey’s HSD test at the level of * ≤ 0.05, ** ≤ 0.01 and *** ≤ 0.001. Mean values ± SDs (n = 3) were provided
