Log₂-fold changes of phospholipids in the flag leaves of the cold-sensitive Wyalkatchem (W) and cold-tolerant Young (Y) after one night (TP₁ vs. TP₀) and prolonged (TP₃ vs. TP₁) of cold treatment. Fold changes were calculated by dividing the normalized response of the variety at a time point (e.g., TP₁) to the normalized response of that variety at the previous time point (e.g., TP₀), then Log₂-transformed. Statistical method and cut-offs are as stated in Fig. 1. Green significant decrease, Red significant increase. There were four biological replicates (n = 4) for all the measured lipids
