The fruit rapidly spoils and collapses, or in lower humidities shrinks and mummifies (Brown and Eckert, 1988; Snowdon, 1990). A, Granny Smith (11 days incubation); B, Rosemarie; C, Beurre Bosc; D, Beurre Hardy (B-D: seven days incubation). Penicillium species are one of the most common causes of fungal spoilage in fruits and vegetables. PdMFS1 can play an important role in the intensification of resistance to fungicides normally used in P. digitatum postharvest treatments. Spore sizes range from 3 to 5 micrometres. Spread of Penicillium digitatum and Penicillium italicum during contact between citrus fruits. At first, small water-soaked areas - greyish, lacking a clear margin - on the fruits, enlarging rapidly to form white rots several centimetres in diameter. All fruits were infected when inoculated with a spore concentration of 6x105/ml. 2019 Aug;123(8):584-593. doi: 10.1016/j.funbio.2019.05.004.

Penicillium digitatum is the main citrus postharvest pathogen and causes green mold disease in citrus fruits, being responsible for important economic losses worldwide [25] [26] [27]. J Microbiol Biotechnol. However, even though Penicillium species are among the most common fungi in the environment, ABPM due to Penicillium species is rare, accounting for only 1.9% of ABPM cases other than Aspergillus fumigatus.In particular, only one case of Penicillium-associated ABPM for which the … Soft rot of citrus fruit caused by Penicillium digitatum … Spore masses develop giving the moulds their characteristic colours - green (Penicilliumdigitatum) and blue (Penicillium italicum) (Photos 1&2). Biochem. P. digitatum causes a destructive fruit rot of citrus. [1] … Bluish asexual spores (conidia) form at the centre of the colony, surrounded by a broad band of white mycelium. Inhibitory effect of gamma irradiation and its application for control of postharvest green mold decay of Satsuma mandarins. It is also found in paint and compost piles. Barkai-Golan R, Karadavid R, 1991. Many Penicillium mold species are actually benign, but the spores they release can still bring various risks for some people. This information is part of a full datasheet Citrus Postharvest Green Mold: Recent Advances in Fungal Pathogenicity and Fruit Resistance. HHS A flavonone pinocembroside inhibits Penicillium italicum growth and blue mold development in ‘Newhall’ navel oranges by targeting membrane damage mechanism. Inclusion of a pouch of KOH in polyethylene wrapped fruit reduces rot (Piga et al., 1997). You may have year-round symptoms or symptoms that flare up only during certain times of the year. Due to the variable regulations around (de-)registration of pesticides, we are for the moment not including any Penicillium culture plates were graciously provided by John I. Pitt , Commonwealth and Industrial Research Organization, Division of Food Processing, North Ryde, New South Wales, Australia. Cough and postnasal drip 4. Certain rootstocks confer increased resistance to fruit decay on grafted trees (McDonald and Wutscher, 1974).Postharvest resistance correlates with production near wounds of phenolic compounds, such as benzoic acid derivatives, and phytoalexins, such as scoparone (6,7-dimethoxycourmarin) and scopoletin, by the fruit tissue (Rodov et at., 1994; Bonnas et al., 1995; Lattanzio et al., 1995) and to the production of chitinase and beta-1,3-glucanase by tissue cultures (Niedz et al., 1994).
