Studysummary In this study, rice straw-derived smoke water enhanced root growth in rice plants by increasing root meristem size and cell proliferation, reducing superoxide accumulation under phosphorus deficiency, and altering internal phosphorus partitioning, although it suppressed root hair elongation, which affected phosphate uptake.
