Time course of PKS8-1 cluster gene expression in the overexpression strain of the aflR-like gene during disease development in banana.

A. Cluster gene expression in the overexpressor and in a vector-transformed control relative to expression in conidia (set to 1) of the respective strains. Black bar = overexpressor strain #4 (OX); hatched bar = vector control #2 (VC). B. Same data as in 8A, but cluster gene expression of the overexpressor is shown relative to expression in the vector-control strain (set to 1). Cluster genes assayed are those shown in Fig 4. Tissue was harvested and assayed weekly starting at 2 weeks post inoculation through 9 weeks. Results are shown as a bar graph in log scale. Error bars indicate standard error from three biological replicates. ND = not detected; W = week.
