Keywords: forage legumes, fungi, seed storage IntroductIon While disease symptoms were observed after seven days incubation at 20ºC on pomegranates inoculated with P. expansum, P. sclerotiorum, P. glabrum (Fig. P. citrinum is the major producer of this toxin, but production by P. expansum and P. verrucosum has also been reliably reported. Often found in aerosol samples (17). They are consumed because of their nutritional and health benefits, in fresh form or as various processed products. Virulence on inoculated onion bulbs varied significantly within isolates of P. glabrum, but the most virulent isolate of P. polonicum and P. glabrum did not differ, nor did they differ from an isolate of P. expansum. The first four fungi were consistently reisolated from decayed fruit. Introduction. is one of the most common global and economically important postharvest fruit rot diseases (Zhong et al., 2018). Fungal cultures in the air of her home were positive for Penicillium expansum and other fungi. Penicillium species are one of the most common causes of spoilage of fruits and vegetables.For example, Penicillium italicum and Penicillium digitatum are frequent causes of rot of citrus fruits, while Penicillium expansum is known to spoil apples and {798, 2539,3090}. expansum were noted on Nules Clementine, Owari Satsuma, Delta Valencia, 'Midknight Valencia', and Eureka seeded for the first time. Penicillium is known worldwide for the species P. notatum of which Dr. Alexander Fleming, in 1928, discovered a powerful antibacterial that we would later know as "penicillin". The blue mould fungus negatively affects fruit quality, thereby reducing fresh fruit consumption, and significantly contributes to food loss. Samples of pear fruits with blue mold and other Penicillium-like mold symptoms . responsible for postharvest decay is unknown. chrysogenum (unii: 3y1pe1gcig) (penicillium chrysogenum var. The genome of the highly aggressive P. expansum strain R19 was re-sequenced and analyzed together with the genome of the less aggressive P. solitum strain RS1. Penicillium expansum Link ex. Penicillium rot - additional information Symptoms and recognition. Penicillium expansum is a psychrophilic blue mold that is common throughout the world in soil. New disease symptoms were observed on nectarine and plum cultivars (Fig. In particular, it can be produced by the apple-decaying mould, Penicillum expansum (5). The most obvious symptom that manifests when Blue Mold is present is the premature rotting of the fruit. expansum (Frisvad and Filtenborg, 1983). To evaluate the curative effect, wounded fruit (5-mm deep and 1-mm wide) were inoculated with a single drop (20 L) of P. expansum suspension (1×105 sporesmL−1), Pyrimethanil resistance was retained at the levels similar to that of the initial generation after 20 and 5 transfers on PDA and 4 and 3 cycles on apple fruit at 20 and 0 degrees C, respectively. A two-year survey was conducted in 2014 and 2015, where four pome fruits (apple, pear, quince, and . A two-year survey was conducted in 2014 and 2015, where four pome fruits (apple, pear, quince, and . Penicillium expansum grows at low temperatures, so only cold storage retards spoilage. Fig. Penicillium marneffei infections have also been reported in non-AIDS patients with hematological malignancies and those . It usually infects fruits after harvest, often being introduced through poor sanitation or quarantine procedures. The species belonging to this section vary from one geographic . Thus, our feature for this month's newsletter is apple blue mold, caused by the fungus Penicillium expansum. The basic immunity is cellular. Symptoms and signs of blue mold caused by Penicillium spp., mainly P. expansum) on apples and pears. In Southeast Asia, P. Mameffci (a possible reservoir - bamboo rats) causes a disease similar to anthraxplasmosis. Pome fruits, in particular apple, is the most widely grown pome fruit in Serbia, and the distribution of Penicillium spp. Although penicillium spp. P. chrysogenum can most often be found indoors, particularly where there is high humidity, dampness, or water damage.P. chrysogenum colonies are blue-green often with a . Penicillium expansum is a post harvest rot that affects a number of different hosts, including citrus fruits, apples, pears and cherries. Stone fruit are highly perishable and susceptible to numerous postharvest pathogens. Penicillium italicum and Penicillium digitatum are the most common attackers of citrus fruits, while Penicillium expansum is known to attack apples. The impact of six local isolates of Penicillium frequentans recovered from healthy sugar beet (Beta vulgaris L.) leaves was evaluated against Cercospora beticola, the causal pathogen of Cercospora sugar beet leaf spot under laboratory and field conditions. Though primarily known as a disease of apples, this plant pathogen can infect a wide range of hosts, including pears, strawberries, tomatoes, corn, and rice. . Blue mold is a postharvest rot of pomaceous fruits caused by Penicillium expansum and a number of other Penicillium species. 976. Penicillium expansum strain PY (preserved in the China General Microbiological Culture Collection Center, accession number 3703) was isolated from infected apples in China, while P. expansum strain FS7 was obtained from the Culture Collection Center of the Department of Agricultural, Environmental and Food Sciences, at the University of Molise . Whole genome scale similarities and differences were examined. Aw 0.78 - 0.88 (5) A wide number of organisms have placed in this genera. The species was isolated from the right shin of a patient and cultured. 2. It can also trigger or worsen asthma symtpoms. Penicillium is a common allergen, triggering allergies such as hypersensitivity pneumonitis and hay fever. The authors noted that the morphological characteristics of the colonies, such as the length and width of the conidia, are characteristic of the genus. ADVERTISEMENTS: In this article we will discuss about the life cycle of penicillium with the help of suitable diagrams. Symptoms: Blue mold is a common postharvest disease on apples and pears worldwide. Photo credit: Achour Amiri (WSU-TFREC) and Chang-Lin Xiao (USDA-ARS). Penicillium expansum is an unspecialized plant parasite, causing storage rots of apples; most freshly isolated strains produce the antibiotic patulin (synonyms : clavacin, expansine) in suitable . Penicillium is among the five most common genera in the outdoor and indoor fungi aerosols {2649, 2747, 2759}. Identification to species is difficult. It is also found in paint and compost piles. 8 9 346 Journal of the Science of Food and Agriculture (in press). (5) It may cause hypersensitivity pneumonitis, allergic alveolitis in susceptible individuals. Penicillium purchasi is a saprophytic fungus that causes a blue mold on grapes. Penicillium-crop interaction is a multifaceted process and mediated by pathogen- and host-derived proteins. Conservative estimates of blue mould incidence in the United States range from 1% to 5% on fungicide-treated fruit (author's personal observation). Previously known as Penicillium notatum, P. chrysogenum is a widely studied Penicillium species, most famous for being one of the sources of penicillin and several other antibiotics. Penicillium expansum, Mucor piriformis and Botrytis cinerea are the most important post-harvest pathogens of apple. Her symptoms, abnormal findings of radiograph, and spirometric abnormalities disappeared after 2 months' avoidance. Penicillium colonies range in colour from blue-green to white, yellow and pink with a velvety or powdery texture. Blue mold, caused by Penicillium spp., is one of the most economically important postharvest diseases of pome fruits, globally. Study revealed that the colony appearance of Penicillium expansum showed significant difference from Penicillium crustosum , which had dense white to bluish green sporulation lacking white margins, whereas colony colour of P. crustosum appeared white to . Penicillium expansum (eight strains, 61.4%) and Penicillium crustosum (five strains, 31.2%). Penicillium species are one of the most common causes of fungal spoilage in fruits and vegetables. been isolated from apples with blue mold symptoms from the major tree fruit producing regions in Washington State and Pennsylvania [4,5]. Penicillium italicum and Penicillium digitatum are the most common attackers of citrus fruits, while Penicillium expansum is known to attack apples. interactions were . Calyx-end blue mold (Fig. Blue mold. Pathogenesis and symptoms of penicilliosis. However, because it is difficult to accurately identify differ- ent Penicillium spp., the extent to which species other than P. expansum contribute to . Abstract. Penicillium expansum and P. italicum, two members of the Expansa and Italica series, respectively, had 99.9% identity to the standard sequences (PSN118and AB688988.1). Penicillium marneffei is a pathogenic fungus and specifically infects patients with AIDS who live at or visit Southeast Asia (Thailand and adjacent countries, Taiwan, and India) where the fungus is endemic [ 565, 2114, 2200 ]. Mycelium of Penicillium: The mycelium is well developed and copiously branched. Penicillium expansum, as the causal agent of blue mould and a main producer of mycotoxin patulin, is a global concern for economic and food safety.To date, the nutritional requirements of the pathogen during infection and patulin biosynthesis are poorly understood. Penicillium rot commonly occurs on all apple varieties at low levels either alone or as a secondary infection on other rots. (Spotts et al., 1999). These methods include amplification of the internal Penicillium expansum has a wide host range, causing similar symptoms on fruits which include apples, pears, cherries, and citrus . While P. expansum is the most common and ag - gressive Penicillium species, other Penicillium spp., some Aspergillus The fungal agent P. expansum showed the highest infection percentage in the germinated and rotten seeds. Blue mold, caused by Penicillium expansum and other Penicillium . In this study, we investigated the effect of ambient pH on growth, ultrastructure alteration, and pathogenicity of P. expansum, as well as accumulation of patulin and expression of genes involved in patulin biosynthesis. Thom, the cause of blue mold, is the most important postharvest pathogen of apples (16). More recent-ly, genotypic characterization has proven very useful to identify Penicillium spp. Commonly found in soil, food, cellulose and grains (17, 5). P. expansum infects fruit primarily through wounds caused by stem punctures or bruises occurring at harvest or during postharvest handling. It can grow at fairly low temperatures (it is a psychrophile), and in low water activity environments. Pome fruits, in particular apple, is the most widely grown pome fruit in Serbia, and the distribution of Penicillium spp. The ability of the strain to decay pomegranates as well as some varieties of apples (Jonagold, Selena and Vanda) under laboratory conditions after inoculation with conidia into the . Symptoms occur as light colored, soft lesions. Red Delicious by both pathogens were compared to physiological parameters of ripening and release of volatile compounds . Penicillium chrysogenum, the predominant isolate in our study, is assigned to section Chrysogena, ser. Phylogenetic analysis identified Penicillium ramulosum and P. expansum as the most commonly occurring species associated with WCR symptoms. Penicillium expansum is the most common and economically important postharvest fruit rot pathogen that causes blue mould (Rosenberger, 1990; Xiao and Boal, 2009). Symptoms were easier to detect on light coloured cultivars. [14][15] It is destroyed by Penicillium expansum is the main agent of blue mold rot (also called soft rot) of apple fruit and many other fruit and vegetables during postharvest and causes high economic losses during storage of these commodities worldwide [].Blue mold symptoms appear as soft, light brown watery lesions that, at the later stages of decay development, turn blue-green due to formation of . ranged from 0 to 0.1. Developed HRT. In the present study, the antifungal effects and potential mechanism of cinnamon oil against P. expansum were investigated. (or expansum) can appear on many types of seed-core fruits, it's most prevalent on apples. Blue mold is the most common storage disease in Ontario. This study aims to determine pathogenicity profiles of P. expansum, P. crustosum, P. solitum and P. digitatum on selected nectarine and plum cultivars, and in part examine . CABI/EPPO, 2006. Blue mould, caused primarily by Penicillium expansum, is a major threat to the global pome fruit industry, causing multimillion-dollar losses annually. penicillium digitatum (unii: 1sb49sv239) (penicillium digitatum - unii:1sb49sv239) penicillium digitatum: 0.1 g in 1 ml: penicillium expansum (unii: 1xsc3bb35z) (penicillium expansum - unii:1xsc3bb35z) penicillium expansum: 0.2 g in 1 ml: penicillium chrysogenum var. The fungus can also enter the fruit through natural openings, i.e. Apple blue mold (Figure 1) is a significant postharvest disease that causes heavy economic losses due to decay in stored apples destined for the fresh market. It is composed of colourless, slender, tubular, branched and septate hyphae. (A)- Kiwifruit showing symptoms of decay, morphological characterization of Penicillium expansum, (B)- Colony morphologyon MEA, (C)- Colony reverse on MEA, (D-E)- Conidia at 40X, (F)- Control kiwifruits which are symptomless, and (G)- Typical symptoms of P. expansum decay after inoculation on kiwifruits. The genome of the highly aggressive P. expansum strain R19 was re-sequenced and analyzed together with the genome of the less aggressive P. solitum strain RS1. Initial infection most often occurs at sites of fruit injury, such as bruises or puncture wounds. Penicillium species are one of the most common causes of fungal spoilage in fruits and vegetables. A number of other fungi can also cause postharvest rots in . Here, we genetically characterized the role of the bZIP transcription factor PeMetR in sulfur metabolism, virulence and patulin . Penicillium expansum. The epiphytic bacterium Rahnella aquatilis, isolated from fruit and leaves of apples, was tested for antagonistic properties against Penicillium expansum and Botrytis cinerea on Red Delicious apple fruit. Penicillium expansum is a major postharvest pathogen that mainly threatens the global pome fruit industry and causes great economic losses annually. Penicillium expansum strain PY (preserved in the China General Microbiological Culture Collection Center, accession number 3703) was isolated from infected apples in China, while P. expansum strain FS7 was obtained from the Culture Collection Center of the Department of Agricultural, Environmental and Food Sciences, at the University of Molise .

The symptoms begin as soft watery light brown areas around injuries or lenticels on the fruit surface. Blue mold is a postharvest rot of pomaceous fruits caused by Penicillium expansum and a number of other Penicillium species. Tissue-response lesions affect fruit quality and some Penicillium spp. Wallingford, UK: CAB International. In in vitro studies, all the six isolates were able to inhibit the mycelial growth of C. beticola with variation in their antagonistic . New citrus-Penicillium spp. Symptoms and Impact. Although infections may start in the field, infected spots often become evident post-harvest, and expand while fruit is in storage. Pencillium fungi are versatile and opportunistic. lenticels, stem ends and the calyx end (Rosenberger et al., 2006). This species has not previously been reported to cause disease of the fruit. Pencillium fungi are versatile and opportunistic. Figure 1. Penicillium expansum, the causal agent of blue mold, is one of the most prevalent post-harvest pathogens, infecting a wide range of crops after harvest.In response, crops have evolved various defense systems to protect themselves against this and other pathogens. Currently penicillin is not obtained from P. notatum but from other species with greater effectiveness such as P. roqueforti.. characteristics. E, Genome synteny map between P. expansum and P. italicum. P. expansum causes a psychrotrophic mold known as blue mold on a variety of horticultural products including apple, peach, nectarines and cherries (Kim et al., 2018). Blue mould caused by Penicillium expansum and other Penicillium spp. 2) (Louw and Korsten, 2014). With a P. expansum infection, initial infected spots appear post harvest while fruit is in storage, and a sharp visible contrast can be seen between . Fourteen isolates of Penicillium were recovered from rotten apple and pear fruit with blue mold symptoms, and from water from . Three Penicillium species were identified: P. polonicum, P. glabrum and P. expansum. In this study Penicillium implicatum Biourge was found to be the cause of a destructive rot of stored pomegranate (Punica granata) fruits. They grow rapidly and release a strong musty odour. P. expansum suspension (1×105 sporesmL−1) applied directly to the injuries. While P. expansum has a wide and variable host range, the symptoms are very similar across all hosts. Penicillium italicum and Penicillium digitatum are the most common attackers of citrus fruits, while Penicillium expansum is known to attack apples. . Patulin is a toxin produced by the P. expansum, Aspergillus, Penicillium, and Paecilomyces fungal species. Penicillium species are one of the most common causes of spoilage of fruits and vegetables.For example, Penicillium italicum and Penicillium digitatum are frequent causes of rot of citrus fruits, while Penicillium expansum is known to spoil apples and {798, 2539,3090}. Apples (Malus domestica) are a major food crop, with 40 million tonnes being produced in the world (10).Therefore, post harvest decay of apples has an enormous economic significance. This disease is an economic concern not only to the fresh-fruit industry but also to the fruit-processing industry because some strains of Penicillium expansum produce the mycotoxin patulin, which can rise to unacceptable levels and thus affect the quality of . 1. Penicillium is among the five most common genera in the outdoor and indoor fungi aerosols {2649, 2747, 2759}. sporulated from the lesions, causing the inoculated species to complete their life cycle. responsible for postharvest decay is unknown. 4), no decay was observed on control fruit and fruit inoculated with P. minioluteum. Progress 07/01/10 to 06/30/15 Outputs OUTPUTS: Phenotype stability, fitness and competitive ability of pyrimethanil-resistant isolates of Penicillium expansum were determined.
