Table S1. Complete lists of differentially expressed genes (DEGs) and functional annotations in Ulva prolifera across a 300-km Yellow Sea drift gradient

This dataset contains the complete lists of differentially expressed genes (DEGs) and their functional annotations in the green-tide macroalga Ulva prolifera across a 300-km drift gradient in the Yellow Sea. The Excel workbook contains three worksheets corresponding to the following pairwise comparisons: 1. Yancheng vs. Lianyungang 2. Lianyungang vs. Rizhao 3. Rizhao vs. Qingdao For each comparison, fold changes were calculated for the latter sampling region relative to the former. Positive log₂FC values indicate higher expression in the latter region, whereas negative values indicate lower expression. DEGs were defined as |log₂FC| ≥ 1 and adjusted p-value < 0.05.
