abstract = {Black leaf mold caused by Pseudocercospora fuligena is an
important fungal disease of tomato in Southeast Asia. The
objective of this study was to evaluate the control of this
disease using high manganese (Mn) applied to the root
substrate and to evaluate the role of the leaf apoplast in
plant response to fungal infection. In a nethouse experiment
in Thailand, Mn above the optimum for plant growth but below
toxicity increased resistance of tomato plants to black leaf
mold. Enhanced resistance caused by Mn was also obtained
when tomato plants were grown under controlled conditions in
a mist chamber and artificially inoculated with the fungus.
Manganese significantly increased plant peroxidases in the
leaf apoplast. The highest peroxidase activity was measured
when plants were inoculated with Pseudocercospora fuligena.
Defense-related proteins in the leaf apoplast increased when
plants were inoculated with Pseudocercospora fuligena but
not when treated with high Mn. It is concluded that Mn above
the optimum level for plant growth can contribute to the
control of Pseudocercospora fuligena in tomato. The Mn
effect on disease resistance is associated with the
activation of plant peroxidases in the leaf apoplast. A
systemic response, possibly mediated by NADH peroxidase
activity, also seems to trigger disease resistance in leaves
with low Mn concentrations.},
