The cold-avoidance response is dependent on Mpphot and BL. (A) Cold-avoidance response in the wild type (shown as WT), the Mpphot^KO mutant (shown as phot^KO), and the Mpphot/Mpphot^KO complementation line (shown as Phot/phot^KO) (Fig. S1) under white-light conditions. Chlorophyll fluorescence images at 22 °C and 5 °C under weak white light (140 µmol photons m⁻²⋅s⁻¹) are shown. To induce the cold-avoidance response, the samples were incubated at 5 °C for 24 h. (B) Quantitative analysis of the samples shown in A using the P/A ratio. (C) Cold-avoidance response of WT cells in different light conditions, including blue (25 µmol photons m⁻² ⋅s⁻¹) and red (35 µmol photons m⁻²⋅s⁻¹) light, and in darkness. The samples were incubated at 5 °C for 24 h. (D) Quantitative analysis of the samples in C using the P/A ratio. (B and D) Error bars represent SDs.
