FIGURE 7

The spatial distribution of the (A) blue and (B) purple groups of polyhydroxyanthraquinones on fungal isolates of P. restrictum (G85) while grown in co-culture with X. cubensis (G536) at 2.5 weeks. The color coding (blue and purple) corresponds to the structures in Figure 1. Each circle represents a sampled location. The polyhydroxyanthraquinones were most intense where the blue or purple circles were brightest. The bottom bar indicates the relative amount of signal as measured via mass spectrometry.
