Additional file 4: of Physiological and iTRAQ-based proteomic analyses reveal the function of exogenous γ-aminobutyric acid (GABA) in improving tea plant (Camellia sinensis L.) tolerance at cold temperature

Table S4: Functional classifications of identified proteins significantly expressed in leaves of tea plants exposed to the treatments T4/T1 for 7 days (25 °C and 4 °C + GABA for T1 and T4, respectively). Each value represents the average of three biological replicates. The average is significant at a p < 0.01 level. At-test value < 0.05 is considered to be significant between treatment T4 and T1.
