Blue light regulates cellulose biosynthesis in an FKF1-dependent manner. A to C, Expression analyses of cellulose synthase genes (A and B) and cell wall synthesis–related genes (C) in different Arabidopsis lines under WL and SBL conditions. Leaf samples of 4-week-old Arabidopsis plants were collected 6 h after dawn and used for RT-qPCR analysis; the data are an average of two technical replicates from three biological replicates. Error bars represent sd (n = 6). Statistically significant difference between different groups was determined by one-way ANOVA. Means not sharing the same letter are significantly different (P < 0.05). GAL, GALACTURONOSYLTRANSFERASE-LIKE; INVC, ALKALINE/NEUTRAL INVERTASE C.
