Principal coordinates analysis of soil microbial communities differentiated by genotypes, time points, and treatment methods. The PCoA plot (top left) shows the distribution of samples, with colors representing sampling times and shapes representing treatment types. Each point represents one sample. The boxplots (right and bottom) display the distribution of PCoA scores along the first and second axes (PCo1 and PCo2) across Type, Time, and Genotype groups, with associated p-values indicating statistically significant differences between groups. Labels: ‘M1’, ‘M6’, ‘M9’ – months post-treatment; ‘BLANK’ – no straw; ‘M’ – mulching; ‘D’ – deep tillage. Statistical significance was assessed using pairwise Wilcoxon tests.
