Pantoea stewartii is a species of plant pathogenic bacteria that causes Stewart's wilt of corn, as well as jackfruit-bronzing disease, bacterial leaf wilt of sugarcane, and leaf blight in rice. P. stewartii is a gram-negative bacterium in the Enterobacterales, a group that also includes Escherichia coli and several other human, animal, and plant pathogens. Most research on this bacterial pathogen to date has been done on strains infecting corn as the other diseases have been identified much more recently. Due to being relatively easy to work with in laboratory research, P. stewartii has been used to study a range of processes in bacterial physiology including quorum sensing, bacterial pigment production, endoglucanase enzymes, and siderophore-mediated iron acquisition.
Glomerella graminicola is an economically important crop parasite affecting both wheat and maize where it causes the plant disease Anthracnose Leaf Blight.
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.
Cadophora malorum is a saprophytic plant pathogen that causes side rot in apple and pear and can also cause disease on asparagus and kiwifruit. 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 and a marine fungus.
Pestalotiopsis sydowiana is a plant pathogen infecting azaleas, heather, loquats, and rhododendrons.
Corynespora cassiicola is a species of fungus well known as a plant pathogen. It is a sac fungus in the family Corynesporascaceae. It is the type species of the genus Corynespora.
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.
Pseudocercospora subsessilis is a fungal plant pathogen infecting chinaberry tree. It is widespread in tropical and subtropical areas on host species of the genera Azadirachta and Swietenia.
Alternaria dauci is a plant pathogen. The English name of the disease it incites is "carrot leaf blight".
Didymella bryoniae, syn. Mycosphaerella melonis, is an ascomycete fungal plant pathogen that causes gummy stem blight on the family Cucurbitaceae, which includes cantaloupe, cucumber, muskmelon and watermelon plants. The anamorph/asexual stage for this fungus is called Phoma cucurbitacearum. When this pathogen infects the fruit of cucurbits it is called black rot.
Nigrospora sphaerica is an airborne filamentous fungus in the phylum Ascomycota. It is found in soil, air, and plants as a leaf pathogen. It can occur as an endophyte where it produces antiviral and antifungal secondary metabolites. Sporulation of N. sphaerica causes its initial white coloured colonies to rapidly turn black. N. sphaerica is often confused with the closely related species N. oryzae due to their morphological similarities.
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.
Pestalotiopsis is a genus of ascomycete fungi in the Sporocadaceae family.
Boxwood blight is a widespread fungal disease affecting boxwoods, caused by Cylindrocladium buxicola. The disease causes widespread defoliation and eventual death.
Zanthoxylum schinifolium, also called mastic-leaf prickly ash, is a species of flowering plant in the Rutaceae, the citrus family.
Alternaria leaf spot or Alternaria leaf blight are a group of fungal diseases in plants, that have a variety of hosts. The diseases infects common garden plants, such as cabbage, and are caused by several closely related species of fungi. Some of these fungal species target specific plants, while others have been known to target plant families. One commercially relevant plant genus that can be affected by Alternaria Leaf Spot is Brassica, as the cosmetic issues caused by symptomatic lesions can lead to rejection of crops by distributors and buyers. When certain crops such as cauliflower and broccoli are infected, the heads deteriorate and there is a complete loss of marketability. Secondary soft-rotting organisms can infect stored cabbage that has been affected by Alternaria Leaf Spot by entering through symptomatic lesions. Alternaria Leaf Spot diseases that affect Brassica species are caused by the pathogens Alternaria brassicae and Alternaria brassicicola.
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.
The Sporocadaceae are a family of fungi, that was formerly in the order Xylariales. It was placed in the Amphisphaeriales order in 2020.
Pseudopestalotiopsis is a genus of plant pathogens in the family Sporocadaceae.
