Comparison of bacterial ASVs on daughter tubers, roots, post-storage seed tubers and seed tubers of Variety A originating from Field 1. Venn diagrams showing the overlap between a seed tubers and daughter tubers, b seed tubers and roots, c seed tubers and post-storage seed tubers of Field-1-unique bacterial ASVs (in red) or all bacterial ASVs (in blue). Sankey diagram of bacterial ASVs transferred from seed tubers to d, g daughter tubers and e, h roots that emerged from the seed tubers; and f, i post-storage seed tubers. “Shared” in blue represents ASVs detected on both sample types. “Unique-Unique” in red represents the overlap of Field-1-unique ASVs on both sample types. The “Unique-Unique” in red is included in the “Shared” in blue. “Lost” in white represents ASVs lost from the seed tuber during vertical transmission. “Acquired” in light grey represents ASVs not transmitted from seed tubers but acquired from the environment. In a–f numbers in the bars indicate the number of ASVs in each category mentioned above. In g–i numbers in the bars indicate the accumulative relative abundance of ASVs in each category mentioned above
