摘要： Green soybean (Glycine max), commonly known as vegetable soybean or edamame, is harvested at reproductive stages 6 to 7 of pod development. At this stage, the seeds are fully grown but still green and not yet mature. Green soybean is a nutritious food high in protein and micronutrients; however, low temperatures negatively impact its production and quality. The mechanisms underlying cold stress in green soybean remain unclear. This study aims to identify differentially expressed genes (DEGs) and key pathways associated with cold tolerance through a comprehensive transcriptomic analysis of cold stress responses in a cold-tolerant green soybean variety at three time points: 3 h, 12 h, and 24 h. We identified 3415 common DEGs across three time points, with significant enrichment in categories such as "rhythmic process", "response to blue light", "fatty acid metabolism", and "fatty acid degradation". Notably, expression patterns of these pathways were similar after 3 and 24 h of cold exposure. Weighted gene co-expression network analysis (WGCNA) revealed 20 distinct modules, with two principal modules-turquoise and blue-correlating with rhythmic processes and fatty acid pathways. Additionally, we analyzed the genetic regulatory networks within these modules and identified four candidate genes (Glyma.04G015200, Glyma.18G202800, Glyma.02G123700 and Glyma.13G266500) potentially linked to cold tolerance. This study enhances our understanding of the molecular mechanisms of cold stress in green soybean and highlights key cold-responsive genes for further research.
