Table 2. Average Shannon–Wiener index based estimates of diversity of family-level PLAVs (for plant-associated virus sequences) and genus-level plant samples and average prevalence of PLAVs, plant viruses and mycoviruses calculated from the 100 sampling points scored either as uncultivated (72 in France in 2010, 74 in France in 2010 and 34 in South Africa) or cultivated (28 in France in 2010, 26 in France in 2010 and 66 in South Africa).
