QRT-PCR analysis of transcripts encoding chloroplast proteins in transgenic WRKY overexpression or knockout/knockdown lines. A, Expression of ABA-related genes in 3-week-old AtWRKY13 and AtWRKY57 mutant lines. B, Wild-type and mutant plants were grown on MS plates with or without norflurazon for 5 d. Samples were harvested and analyzed using QRT-PCR in duplicate. Expression values are shown and color coded for visual representation: yellow, unchanged; green, reduced; red, induced. Underlined values indicate statistically significant differences (P < 0.05) compared with the expression in Col-0 within the same treatment.
