Ramie (Boehmeria nivea L.) is a highly valued fiber crop. Its yield is often limited by lack of available phosphate (Pi) in the soil, but the underlying molecular mechanisms of ramie's response to Pi deficiency remain largely unknown. To investigate how ramie adapts to low Pi stress, we selected a low Pi-tolerant variety (H-5) and a low Pi-sensitive variety (XYL), and conducted a biochemical and transcriptomic analysis on roots and leaves of both varieties. After subjecting the plants to Pi-deficient and Pi-sufficient conditions for 15 days, we found that H-5 exhibited higher dry weight, longer root systems, and higher levels of Pi, galactolipids, and organic acids when subjected to Pi deprivation, compared to XYL. Transcriptomic analysis further revealed that Pi-responsive genes involved in lipid metabolism, Pi transport, organic acid synthesis, and acid phosphatase activities were more induced in the tolerant variety H-5. Furthermore, weighted gene co-expression network analysis (WGCNA) identified five hub genes, including phosphate transporter, SPX domain-containing protein and sulfoquinovosyl transferase, which played key roles in low Pi tolerance in ramie. The present study will broaden our comprehension of the differences and molecular mechanisms of different ramie cultivars in response to Pi starvation, and lay a foundation for future agronomic improvements in ramie and other fiber crops
