Figure 1.

Evaluation of WT and GFP-expressing transformants of B. squamosa, B. aclada and S. cepivorum. (a) No differences were observed between WT and transformants based on morphology and growth on agar plates (first row) and pathogenicity on host tissue (second row), and only transformant strains are able to fluoresce (third and fourth row). Scale bar = 500 µm. (b) No difference was observed in growth rate between WT and transformants (unpaired t-test, p > 0.05, error bars representing standard error).
