  1. aPhloem and xylem represent the phloem and xylem of apple twigs; Healthy tree seeds and diseased tree seeds represent the apple seeds collected from healthy trees or diseased trees;
  2. bN indicates the total number of different tested apple twig tissues or tested apple seeds;
  3. cps indicates the proportion of apple twig tissues or apple seeds infected with V. mali;
  4. dLogC represents the log concentration of the V. mali genomic DNA copies in apple twig tissues or apple seeds; “—” indicates the concentration of V. mali genomic DNA copies in apple seeds from healthy trees is 0 copies g−1; the statistical analysis of LogC between different apple twig tissues or apple seeds was performed with independent sample T test, where P < 0.05 indicates significant difference.
