Special Issue Information

Dear Colleagues,

This Special Issue of Metabolites focuses on the metabolic changes in plants in response to abiotic stress. The global environment is changing rapidly, and extreme temperatures, drought, salinity and heavy metal toxicity are constantly challenging plant growth. The potential topics of relevance to this SI cover various aspects of abiotic stress metabolism, including the accumulation of compatible sol-vents, activation of the antioxidant system, regulation of energy metabolism and changes in lipid metabolism. Understanding these metabolic changes will be crucial to developing strategies for enhancing plant stress tolerance and increasing productivity in challenging environments. This Special Issue aims to provide valuable insights into the complex mechanisms underpinning the metabolic response to plant biosecurity.

Green soybean (Glycine max (L.) Merrill) is a highly nutritious food that is a good source of protein and fiber. However, it is sensitive to low temperatures during the growing season, and enhancing cold tolerance has become a research hotspot for breeding improvement. Background/Objectives: The underlying molecular mechanisms of cold tolerance in green soybean are not well understood. Methods: Here, a comprehensive analysis of transcriptome and metabolome was performed on a cold-tolerant cultivar treated at 10 °C for 24 h. Results: Compared to control groups, we identified 17,011 differentially expressed genes (DEGs) and 129 differentially expressed metabolites (DEMs). The DEGs and DEMs were further subjected to KEGG functional analysis. Finally, 11 metabolites (such as sucrose, lactose, melibiose, and dehydroascorbate) and 17 genes (such as GOLS, GLA, UGDH, and ALDH) were selected as candidates associated with cold tolerance. Notably, the identified metabolites and genes were enriched in two common pathways: ‘galactose metabolism’ and ‘ascorbate and aldarate metabolism’. Conclusions: The findings suggest that green soybean modulates the galactose metabolism and ascorbate and aldarate metabolism pathways to cope with cold stress. This study contributes to a deeper understanding of the complex molecular mechanisms enabling green soybeans to better avoid low-temperature damage. Full article
