turcicum pectic enzymes are not involved in lesion
formation. Rather, wilting occurs due to extensive
plugging by hyphae thus physically obstructing water
flow (Jennings & Ullstrup, 1957; Tagne et al., 2002).
The production of germ tubes from the tips of the
broken hyphal strands could be a contributor to
aggressiveness and isolates producing germ tubes
from the broken hyphal fragments were found to be
comparatively more aggressive than the isolates
without this attribute.
