Example of expression of genes induced or repressed by Arabidopsis after exposure to HL and fHL treatments for 1 h (see Fig. 1). Data are an average of three experiments and genes represented by multiple spots were averaged. Ratios < 2× are considered unchanged. The complete list is provided in the supplemental data.
