[Synechococcus WH8102 gene expression under P treatments] - RNA-seq gene expression data for Synechococcus sp. WH8102 under continuous high, mid, and low phosphorus treatments in laboratory EFB experiments in 2025 (Collaborative Research: Assessing the role of polyphosphate production and cycling in marine ecosystem functioning)

WH8102 grown under controlled laboratory phosphorus treatments (High-P, Mid-P, and Low-P) in 2025. Gene expression was measured across three biological replicates per treatment and includes 2,718 genes with locus_tag identifiers, along with gene names and functional product annotations where available.

Normalized counts were generated using DESeq2 (median-of-ratios size factor method), enabling comparison across samples and are provided in the supplemental table 998248_v1_Syn_WH8102_normalized_counts_annotated.csv. Many genes lack assigned names, reflecting the prevalence of hypothetical or predicted proteins typical of cyanobacterial genomes. In addition to normalized counts, the dataset includes a differential expression table reporting pairwise comparisons between treatments as log2 fold changes (primary dataset: 998248_v1_log2fc_gene_expression_wh8102.csv), along with adjusted p-values and directionality of expression changes.
