“…Amino acids are considered to be one of the most important and effective organic osmoregulation substances [ 23 ]. Sulfur-containing amino acids are the precursors of the endogenous antioxidant glutathione and vitamins, which were found to be important for plant stress tolerance [ 24 ].…”

“…The results of GO enrichment and KEGG enrichment show that the effects of calcium nitrate on tomato are mainly concentrated on ion transport and cell components, while the phenylpropanoid biosynthesis pathway is enriched from the comparison of SL vs. S. Phenylpropanes are ubiquitous in plants, and the phenylpropanoid biosynthesis pathway can form most secondary metabolites in plants. There has been evidence that phenylpropanoid contributes to plant growth and development as well as stress responses [ 24 , 26 ].…”

In recent times, the excessive accumulation of nitrate has been one of the main reasons for the secondary salinization of greenhouse soils. Light plays a key role in a plant’s growth, development, and response to stress. A low-red to far-red (R:FR) light ratio could enhance plant salinity tolerance, but the mechanism at a molecular level is unclear. Thus, we analyzed the transcriptome responses of tomato seedlings to calcium nitrate stress under either a low R:FR ratio (0.7) or normal light conditions. Under calcium nitrate stress, a low R:FR ratio enhanced both the antioxidant defense system and the rapid physiological accumulation of proline in tomato leaves, which promoted plant adaptability. Using weighted gene co-expression network analysis (WGCNA), three modules including 368 differentially expressed genes (DEGs) were determined to be significantly associated with these plant traits. Functional annotations showed that the responses of these DEGs to a low R:FR ratio under excessive nitrate stress were enriched in the areas of hormone signal transduction, amino acid biosynthesis, sulfide metabolism, and oxidoreductase activity. Furthermore, we identified important novel hub genes encoding certain proteins, including FBNs, SULTRs, and GATA-like transcription factor, which may play a vital role in low R:FR light-induced salt responses. These findings offer a new perspective on the mechanisms and environmental implications behind low R:FR ratio light-modulated tomato saline tolerance.
