Cosegregation of the appressorium deficiency
phenotype with the mpg1Hph deletion allele.
Reintroduction of MPG1 restores pathogenicity,
appressorium development and cell surface
hydrophobicity

appressoria build turgor during incubation
1-6 gt hardness
water incubation softer earlier penetration
PEG gt conc
gthardness lower pressure to inhibit penetration

MST1 is dispensable for mobilization of glycogen
and lipid storage molecules
A. Glycogen stained with iodine moved from
conidia to appressoria and degraded
B. Lipid droplets stained with Nile Red Upper
DIC Lower epifluorescence
