The mutation of RAPTOR1B has considerable effects on the expression of ROS-responsive genes and genes coding for proteins involved in photosynthesis and tetrapyrrole biosynthesis. Seedlings were grown in the dark for 5 d and then transferred to light. Samples were collected immediately prior to light exposure (5dD) or 1 h after illumination (5dD + 1hL). A, Heat map showing the fold changes of the expression of ROS-responsive genes in Col-0 and rb10 after exposure to light for 1 h with respect to samples without light treatment (5dD + 1hL versus 5dD). B and C, PageMan heat map showing fold changes of transcripts (rb10 versus the wild type) in different functional categories of photosynthesis (B) and tetrapyrrole synthesis (C). The means of the data points (log₂ values) in each bin were used for the heat map.
