However, when the peel is wounded, during harvesting or subsequent handling and processing, P. digitatum spores germinate and their germ tubes may penetrate the fruit, to initiate infection and, eventually, to develop the typical green mold symptoms. Cough and postnasal drip 4. These molds commonly contaminate clinical specimens and cause contamination in the laboratory. If you do have an allergy to Penicillium, your immune system’s response will be to trigger symptoms like itchy and watery eyes, sneezing, nasal congestion, itchy lips, mouth and nose, or a runny nose. in the citrus supply chain, and confirm the … Penicillium digitatum; X33 antifungal metabolite; antifungal mechanism; citrus green mold; proteomic. Penicillium digitatum is a widespread pathogen among Rutaceae species that causes severe fruit decay symptoms on infected citrus fruit (known as citrus green mold). However, in immunocompromised hosts they can be virulent pathogens and can cause death. P. digitatum causes a destructive fruit rot of citrus. Identification to species is difficult. Proteomic 11 1–3. Symptoms & Life Cycle. The employment of fungicides can effectively control the citrus green mold, significantly reducing agricultural economic loss. NIH Citrus fruits infected with the fungus Penicillium digitatum substantially increase the production of the plant hormone ethylene. Barmore CR, Brown GE, 1982.

Epub 2019 May 13. Penicillium Mold Health Effects. Decay started as softening and discolouring (browning) of infected and colonised tissue. The lesion spreads more rapidly than those caused by P. italicum. SUMMARY . Barkai-Golan R, Karadavid R, 1991. (A) Incidence of infection of inoculated wounds. Immunocompromised people those with immune systems that are not functio… Itchy eyes, nose and throat 5. P. digitatum causes a destructive fruit rot of citrus. The improved alkaline phosphatase activity and extracellular conductivity, increased H2O2 and malondialdehyde contents, and inhibition of energy, amino acid, and sugar metabolism indicated that the oxidative stress of P. digitatum is induced by the X33 antifungal extract. Spore masses develop giving the moulds their characteristic colours - green (Penicilliumdigitatum) and blue (Penicillium italicum) (Photos 1&2). A total of 277 differentially expressed proteins, consisting of 207 upregulated and 70 downregulated, were identified from the comparative proteomics analysis.
