Figure 5.

Amino acids concentration in leaves of tomato recombinant inbred line (RIL)-66 and RIL-76 under salinity, heat, or the combination of salinity and heat. (A) Heat map of the amino acid concentration (expressed as log₂) in tomato leaves of RIL-66 (salinity + heat sensitive) and RIL-76 (salinity + heat tolerant) under salinity heat and the combination of salinity+heat. Stars are representative of significant differences p < 0.05 (*p < 0.05, **p < 0.01, ***p < 0.001) respect to control plants. (B–E) Absolute concentration of the main amino acids related to nitrogen assimilation pathway. Bars are mean values ± SE (n = 6), and bars with different letters are significantly different at p < 0.05 according to Tukey's test. (n = 6).
