Cadophora malorum is a saprophytic plant pathogen that causes side rot in apple [3] and pear [4] and can also cause disease on asparagus [5] and kiwifruit. [6] C. malorum has been found parasitizing shrimp and other fungal species in the extreme environments of the Mid-Atlantic Ridge, and can be categorized as a halophilic psychrotrophic fungus [7] and a marine fungus. [8]
Cadophora malorum was first described as Sporotrichum malorum in 1924 by Mary Nest Kidd and Albert Beaumont, [1] [9] from a specimen collected on an apple tree in Britain, [10] but in 2000 was transferred to the genus, Cadophora , by Walter Gams, a German mycologist. [1] Extensive gene analysis has been done confirming the work of Walter Gams and categorizing C. malorum in the genus of Cadophora and distinguishing it from the previously named genus Phialophora. [11]
C. malorum is classified as a part of the Ascomycota division, because of the presence of asci and ascospores in its sexual reproductive lifecycle. C. malorum also shares typical morphological qualities with the Leotiomycetes class, Helotiales order, and the Ploettnerulaceae family. The Capophora genus has also been shown to be classified as ectomycorrhizal fungi (ECM fungi) [12] and as dark septate endophytes (DSE). [13]
C. malorum has been observed to infect pears during the post-harvest stage. C. malorum does not however infect pears until after some decay has already occurred. [4] The source of inoculum for C. malorum has been shown to be in the soil, where the spores can overwinter and survive all year round off of nutrients released into the soil from decaying fruit. C. malorum can infect wounded bark and cause cankers to form in the trunk of the infected tree. [4] C. malorum also can cause dieback in the leaves and fruit through wilting, yellowing, and necrosis of the plant. This has been known to happen on sunflower plants [14] and kiwi trees. [15]
Research has been conducted with isolation of C. malorum from shrimp [7] and other fungal species, [8] but research was not specific about how C. malorum infects organisms outside of the plantae kingdom. There is a lot of potential for further research in this area as it is rare for fungal species to be able to infect both plants and animals. [16]
C. malorum has been documented to be found parasitizing organisms all over the globe, showing up in research done in Slovenia, [17] Russia, [14] Chile, [15] United States, [3] Germany, [18] Italy, [19] along with various other countries. C. malorum has also been found in moderate to extreme environments such as the Mid-Atlantic Ridge [7] and Antarctica. [20]
Marine-derived fungi, like C. malorum, have been used to research biotechnological advances for a long time. Fungi have been used to create many modern products that are still used today, such as: dyes, flavors, fragrances, hallucinogens, poisons, and pesticides. [21]
Marine fungi produce valuable secondary metabolites that can lead to innovations in potential drug-therapies. [8] The secondary metabolites in C. malorum give an advantage for its own pathogenicity, but can also be used in developing beneficial pharmaceuticals, different food additives, and types of perfumes. [21]
C. malorum was discovered to possess these secondary metabolites along with genes encoding for carbohydrate-active enzymes, signifying that these genes have been adapted to extreme environments and thus have high biotechnological potential. [8] [7] C. malorum secondary metabolites can be used to develop various pesticides such as insecticides. [21] Using living organisms as a pest control mechanism has been proven to be a useful, environmentally conscious, and sustainable method rather than the typical chemicals used. [22]
Fusarium ear blight (FEB), is a fungal disease of cereals, including wheat, barley, oats, rye and triticale. FEB is caused by a range of Fusarium fungi, which infects the heads of the crop, reducing grain yield. The disease is often associated with contamination by mycotoxins produced by the fungi already when the crop is growing in the field. The disease can cause severe economic losses as mycotoxin-contaminated grain cannot be sold for food or feed.
Rhizopus arrhizus is a fungus of the family Mucoraceae, characterized by sporangiophores that arise from nodes at the point where the rhizoids are formed and by a hemispherical columella. It is the most common cause of mucormycosis in humans and occasionally infects other animals.
Glomerella graminicola is an economically important crop parasite affecting both wheat and maize where it causes the plant disease Anthracnose Leaf Blight.
Pseudocercosporella capsellae is a plant pathogen infecting crucifers. P. capsellae is the causal pathogen of white leaf spot disease, which is an economically significant disease in global agriculture. P. capsellae has a significant affect on crop yields on agricultural products, such as canola seed and rapeseed. Researchers are working hard to find effective methods of controlling this plant pathogen, using cultural control, genetic resistance, and chemical control practices. Due to its rapidly changing genome, P. capsellae is a rapidly emerging plant pathogen that is beginning to spread globally and affect farmers around the world.
Alternaria japonica is a fungal plant pathogen. It is a cause of black spot disease in cruciferous plants. It is not a major source of crop loss, but is considered dangerous for plants during the seedling stage.
Mucor piriformis is a plant pathogen that causes a soft rot of several fruits known as Mucor rot. Infection of its host fruits, such as apples and pears, takes place post-harvest. The fungi can also infect citrus fruits.
Stemphylium globuliferum is a plant pathogen infecting alfalfa.
Pestalotiopsis sydowiana is a plant pathogen infecting azaleas, heather, loquats, and rhododendrons.
Pseudocercospora fuligena is a fungal plant pathogen infecting tomatoes. It is the cause of the fungal disease black leaf mold. The fungus was first described in the Philippines in 1938 and has since been reported in numerous countries throughout the tropics and subtropics. It was reported in the United States in 1974, initially in Florida, and has since been reported in non-tropical regions including Ohio and North Carolina.
Fusarium sacchari is a fungal and plant pathogen of crops including sugarcane in China.
Neocosmospora vasinfecta is a fungal plant pathogen that causes, among other types of infections soybean stem rot.
Pseudocochliobolus eragrostidis is a plant pathogen infecting commelinids.
Fusarium acuminatum is a fungal plant pathogen.
Puccinia thaliae is the causal agent of canna rust, a fungal disease of Canna. Symptoms include yellow to tan spots on the plant's leaves and stems. Initial disease symptoms will result in scattered sori, eventually covering the entirety of the leaf with coalescing postulates. Both leaf surfaces, although more predominant on the underside (abaxial) of the leaf, will show yellow to brownish spore-producing these pustulate structures, and these are the signs of the disease. Spots on the upper leaf-surface coalesce and turn to brown-to-black as the disease progresses. Infection spots will become necrotic with time, with small holes developing in older leaves. These infected leaves eventually become dry and prematurely fall.
Verticillium nonalfalfae is a soilborne fungus in the order Hypocreales. It causes verticillium wilt in some plant species, particularly Ailanthus altissima. The fungus produces a resting mycelium characterized by brown-pigmented hyphae. It is most closely related to V. dahliae and V. alfalfae.
Cranberry fruit rot (CFR) is a disease complex of multiple fungal agents affecting the American cranberry. Cranberry fruit rot can be categorized into field rot and storage rot. The importance of field rot and fruit rot depends on how the cranberries will be processed after harvest. If cranberries are immediately processed after harvest, growers focus on preventing field rot while with fresh market cranberries, growers seek to prevent storage rot. There are 10-15 fungal pathogens known to cause cranberry fruit rot diseases, some active in only field rot, storage rot, or both. The majority of these fungal pathogens are ascomycetes, with the rest being deuteromycetes. There is no known bacterial pathogen that plays a role in CFR or any major disease on cranberry, potentially due to the low pH conditions on the cranberry fruit.
Bitter rot of apple is a fungal disease of apple fruit that is caused by several species in the Colletotrichum acutatum and Colletotrichum gloeosporioides species complexes. It is identified by sunken circular lesions with conical intrusions into the apple flesh that appear V-shaped when the apple is cut in half through the center of the lesion. It is one of the most devastating diseases of apple fruit in regions with warm wet weather.
Epicoccum sorghinum is an ascomycete fungus with known plant pathogenicity to sugarcane and rice, causing ring spot disease and leaf spot disease. This fungus is primarily known for its production of tenuazonic acid, which leads to complications with growth and causes the symptoms of leaf spot disease. Tenuazonic acid not only affects plant growth, but has recently been proven to impact human health due to its prevalence in food and beverages. It is widely dispersed, affecting multiple hosts in different countries. Although not a serious threat, Epicoccum sorghinum has been known to influence the sorghum grain-mold complex in ways which reduce crop yields, seed viability, and kernel weight. As a result of continuous phylogenetic and morphological discoveries relevant to Epicoccum sorghinum, this fungus has undergone a number of name changes.
Mucor fragilis is an endophytic fungus that causes the mold that can be found on grapes, pole beans, loquat, and on the roots of medicinal plants like Radix pseudostellariae. It belongs to the order Mucorales and phylum Mucoromycota. The observed symptoms showed the presence of fluffy and soft fungal mycelium with white to dark brown discoloration that deteriorated the beans and grapes quality.
Lambertella corni-maris is a small ascomycete fungi. It grows in deciduous fruit areas, and causes postharvest Lambertella rot on apple fruits. The species also forms a mycoparasitism relationship with Monilinia fructigena. It is the type species of the genus Lambertella.
