“…Elevated CO 2 confers tomato tolerance to progressively higher soil salinity and secondary soil salinization by improving antioxidant capacity, ion homeostasis, and PA metabolism, decreasing ABA and ET levels, and suppressing transpiration ( Yi et al, 2015 ; Brito et al, 2020 ; Zhang et al, 2020c ). Furthermore, low red light (R) to far-red light (FR) ratio (R:FR) enhances salinity tolerance in tomato by regulating photosynthesis and ROS scavenging systems ( Wang Y. et al, 2021 ).…”

“…Light spectrum-dependent alterations in ROS content under changing environmental conditions result in an appropriate adjustment of the antioxidant levels, which improves stress tolerance ( Figure 2 ). In this respect, the low R:FR ratio reduced the salinity-caused damage by the induction of SOD, POD, CAT, and APX at gene expression and enzyme activity levels in tomatoes [ 89 , 90 ]. The spectral control of the antioxidant-dependent adaptive responses was also demonstrated in wheat [ 91 ].…”

“…Under salt stress, low R/FR increased the stability of Phytochrome interaction factor (PIF) and upregulated brassinosteroid and auxin signaling, thus promoted hypocotyl growth in Arabidopsis (Hayes et al, 2019). Low R/FR also upregulated SODCC.2, GPX1, APX2 and CAT1 gene expressions and increased antioxidant enzyme (e.g., SOD, POD and CAT) activities, thus enhanced salt resistance in tomato plants (Cao et al, 2018;Wang Y. et al, 2021). Cockburn et al (1996) found that under salt stress, low R/FR enhanced PEP carboxylase activity, and caused accumulation of CAM isoform of PEP carboxylase isozyme and increased terpineol and soluble carbohydrate contents, finally improved salt tolerance in Mesembryanthemum crystallinum plant.…”
