(a), The colonies of leaf resident filamentous fungi (5–15 mm in diameter), yeasts and bacteria (0.1–2 mm in diameter) visualized by leaf printing onto a 0.2 × PDA medium plate from a wild Arabidopsis thaliana. (b), Typical yeast colonies on 0.2 × PDA medium, seven days after plating 20 μL of leaf-wash solution from sample A (Table 1). Similar plates with lower colony density from plating 1:10 or 1:100 dilutions of leaf-wash were used for colony picking. Scale bar: 1 cm.
