Significant microbial community changes in response to treatment and genetic modification. The composite volcano plot illustrates changes in microbial community composition at the genus level across different treatment methods (deep tillage vs. mulching, represented in top and bottom rows of the M/D panels) and genetic modifications (GM vs. non-GM, shown in top and bottom rows of the G/N panels). Each data point marks a genus, with significant changes highlighted in red (P value < 0.05) and non-significant changes in blue (P value ≥ 0.05). Key microbial genera are annotated to denote increased or decreased abundance due to treatments.
