Venn diagram of the number of differentially expressed genes (DEGs). The number and percentage of down-regulated genes (A) and up-regulated genes (B) in warming treatments in relation to the control condition of cold-acclimated plants, 8 °C/0 °C (CA). Warming treatments received the following thermoperiods: 8 °C/6 °C, nocturnal warming (NW+); 14 °C/0 °C, diurnal warming (DW+); and 14 °C/6 °C, diurnal-nocturnal warming (DNW+). The plants were cultivated in chambers under controlled conditions at a photoperiod and thermoperiod of 18 h/6 h duration.
