Penicillium 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 کاملIntegrated Approaches to Postharvest Disease Management in California Citrus Packinghouses
Practices in the citrus industry evolve rapidly to minimize postharvest decay losses, mostly a result of green mold or blue mold, caused by Penicillium digitatum or P. italicum, respectively. Current problems include the continued development of fungicide resistance among these pathogens, and compliance with emerging secondary residue standards and other privatized regulation of production and ...
متن کاملAssays to Detect β-Tubulin Codon 200 Polymorphism in Trichuris trichiura and Ascaris lumbricoides
BACKGROUND The soil-transmitted helminths (STH) Ascaris lumbricoides and Trichuris trichiura are gastrointestinal parasites causing many disabilities to humans, particularly children. The benzimidazole (BZ) drugs, albendazole (ALB) and mebendazole (MBZ), are commonly used for mass treatment for STH. Unfortunately, there is concern that increased use of anthelmintics could select for resistant p...
متن کاملbenzimidazole -resistance in haemonchus contortus : new pcr-rflp method for the detection of point mutation at codon 167 of isotype 1 β-tubulin gene
b ackground: due to the lack of a suitable and economic test for the analysis of the polymorphism at codon 167, we developed a new pcr-rflp technique, based on a modified forward primer (ut- hc167 mf-primer), to identify simultaneously the snps at codons 167 and 200 of isotype 1 β-tubu- lin gene of haemonchus contortus . m ethods: there already are several safe and easy methods for identificati...
متن کاملPenicillium 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...
