Nwt colony phenotype was experimentally reproducible by oak passage experiment. a Scraping off the outer bark 20 weeks post-inoculation revealed diseased tissue. The red mark at the center indicates the inoculation point. Isolates recovered from circle and square marks yielded wt and nwt colonies, respectively. b Isolates show diverse colony morphology. Top left: Pr-745 (wt, bay), top right: Pr-710 (wt, bay), both are wild type isolates used as inocula. Middle left and right: examples of re-isolates from canyon live oak showing nwt colony morphology. Bottom left: a re-isolate from canyon live oak showing a wt colony morphology, bottom right: an example of early senescence
