“…Most of the JAZ -related genes were down-regulated in LJ11 and up-regulated in LJ25, implying that the JA pathway may play a positive role in CS-response in LJ11 compared to LJ25. However, the responses of SA and BR hormonal pathways to CS are primarily reported in Arabidopsis [ 87 ] and other crops, including cucumber [ 88 ], while the indicated study in rice is not well studied. In this study, 21 SA-related and seven BR-related genes were identified.…”

Background Rice is one of the most important cereal crops in the world but is susceptible to cold stress (CS). In this study, we carried out parallel transcriptomic analysis at the reproductive stage on the anthers of two Japonica rice varieties with contrasting CS resistance: cold susceptible Longjing11 (LJ11) and cold resistant Longjing25 (LJ25). Results According to the obtained results, a total of 16,762 differentially expressed genes (DEGs) were identified under CS, including 7,050 and 14,531 DEGs in LJ25 and LJ11, respectively. Examining gene ontology (GO) enrichment identified 35 up- and 39 down-regulated biological process BP GO terms were significantly enriched in the two varieties, with ‘response to heat’ and ‘response to cold’ being the most enriched. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis identified 33 significantly enriched pathways. Only the carbon metabolism and amino acid biosynthesis pathways with down-regulated DEGs were enriched considerably in LJ11, while the plant hormone signal transduction pathway (containing 153 DEGs) was dramatically improved. Eight kinds of plant hormones were detected in the pathway, while auxin, abscisic acid (ABA), salicylic acid (SA), and ethylene (ETH) signaling pathways were found to be the top four pathways with the most DEGs. Furthermore, the protein-protein interaction (PPI) network analysis identified ten hub genes (co-expressed gene number ≥ 30), including six ABA-related genes. Various DEGs (such as OsDREB1A, OsICE1, OsMYB2, OsABF1, OsbZIP23, OsCATC, and so on) revealed distinct expression patterns among rice types when the DEGs between LJ11 and LJ25 were compared, indicating that they are likely responsible for CS resistance of rice in cold region. Conclusion Collectively, our findings provide comprehensive insights into complex molecular mechanisms of CS response and can aid in CS resistant molecular breeding of rice in cold regions.

“…Similarly, Tekin & Ceyhan (2020) reported that an increase in SOD activity was observed in pea plants exposed to cold stress. Salicylic acid has also been shown to increase SOD enzyme activity in alfalfa, cucumber, barley, and potato plants under cold stress (Golovatskaya et al, 2023;Ignatenko et al, 2021;Mutlu et al, 2016;Wang et al, 2023). Shoot PDH47 expressions increased with the intensity of stress on day 1 of stress application without SA treatment (Figure 2).…”

The most significant crop losses worldwide occur due to unfavorable temperatures such as heat, drought, cold, and freezing. Bioregulator substances like salicylic acid can play important roles in the growth, development, and stress responses of plants. In this study, changes in stem/root length and relative water content of peas under cold and freezing stress, as well as antioxidant system indicators such as proline, malondialdehyde, hydrogen peroxide, chlorophyll and ion leakage levels were investigated. The expressions of genes coding for the TOP2 and PDH47 enzymes, which play important roles in the replication, transcription, and repair of DNA molecules, were also examined in root and stem tissues in the presence of two different concentrations of salicylic acid under cold and freezing stress. The results have shown that the application of salicylic acid, when added to the growth medium, can have positive effects on the cold resistance of pea plants. Salicylic acid likely achieves some of its effects by increasing the activity of superoxide dismutase, one of the most important enzymes taking a role in combating reactive oxygen species. The data obtained indicate that salicylic acid also increased the expressions of TOP2 and PDH47 genes, which can both change the topology of DNA, possibly facilitating the transcription of genes taking a role in antioxidative defense. Salicylic acid also reduced the levels of reactive oxygen species hydrogen peroxide and maintained cell membrane integrity, which leads to a decrease in ion leakage and an increase in water-holding capacity. With this study, the mechanisms of action of salicylic acid in cold stress tolerance have been further elucidated, and its potential use in agricultural cultivation has been evaluated.
