Penicillium digitatum Suppresses Production of Hydrogen Peroxide in Host Tissue During Infection of Citrus Fruit.
ABSTRACT During the infection of citrus fruit by Penicillium digitatum there is little evidence of a host defense response. This suggests that P. digitatum has the ability to suppress host defenses. The current study demonstrates that P. digitatum suppresses a defense-related hydrogen peroxide (H(2)O(2)) burst in host tissue. In contrast, the nonhost pathogen, Penicillium expansum, triggers pro...
متن کاملPenicillium digitatum metabolites on synthetic media and citrus fruits.
Penicillium digitatum has been cultured on citrus fruits and yeast extract sucrose agar media (YES). Cultivation of fungal cultures on solid medium allowed the isolation of two novel tryptoquivaline-like metabolites, tryptoquialanine A (1) and tryptoquialanine B (2), also biosynthesized on citrus fruits. Their structural elucidation is described on the basis of their spectroscopic data, includi...
متن کاملMini-review: Heat treatments for the control of citrus postharvest green mold caused by Penicillium digitatum
Postharvest green mold, caused by the pathogen Penicillium digitatum (Pers.:Fr.) Sacc., is the most economically important postharvest disease of citrus fruits in Spain, areas with Mediterranean climate, and citrus production areas worldwide characterized by low summer rainfall. Economic losses due to this disease have been typically reduced through the application of synthetic chemical fungici...

Methionine-induced Ethylene Production by Penicillium digitatum.
Shake cultures, in contrast to static cultures of Penicillium digitatum grown in liquid medium, were induced by methionine to produce ethylene. The induction was concentration-dependent, and 7 mM was optimum for the methionine effect. In the presence of methionine, glucose (7 mM) enhanced ethylene production but did not itself induce ethylene production. The induction process lasted several hou...
