Importance and distribution
Biochemical importance of the genus, chemical diversity or applications
Helminthosporium produces wide range of compounds. Steiner (1971) reported Helminthosporoside from the sugar cane fungus pathogen Helminthosporium sacchari. Tsuda et al. (1972) studied the chemical components of the Lipid of Helminthosporium oryzae. De Mayo et al. (1962) reported Helminthosporal, a toxin from Helminthosporium Sativum. Shotwell and Ellis (1976) reported pigments such as polyhydroxyanthraquinones, polyhydroxyxanthones, antibiotics such asophiobolins, monocerins, siccanin, and helmintin and mycotoxin such as sterigmatocystin, phytotoxin such as helminthosporal from Helminthosporium (Shotwell & Ellis 1976). Kono et al. (1980) reported two host-specific pathotoxins, Band 1- and Band 2- toxins from Helminthosporium maydis, race T, which is the causal agent of Southern corn blight disease.
There are 501 Helminthosporium epithets in Index Fungorum (2022), but many species have been transferred to other genera such as Acroconidiellina, Acrogenospora, Alternaria, Alternariaster, Antennatula, Bipolaris, Bitunicostilbe, Brachysporium, Chaetosphaerella, Cladosporium, Cochliobolus, Corynespora, Curvularia, Dendryphion, Dendryphiopsis, Drechslera, Ellisembia, Ellismarsporium, Endophragmiella, Eriocercospora, Eversia, Exosporium, Exserohilum, Hyphosoma, Minimelanolocus, Nakataea, Neopodoconis, Ormathodium, Paratomenticola, Passalora, Penzigomyces, Phragmocephala, Pirozynskiella, Pleurophragmium, Pseudocercospora, Pseudopithomyces, Pyrenophora, Pyriculariopsis, Questieriella, Repetophragma, Septoidium, Sirosporium, Solicorynespora, Spadicoides, Spiropes, Sporhelminthium, Sporidesmium, Stemphylium, Stigmina, Strigopodia, Strossmayeria, Thysanorea, Utrechtiana, Venturia and Zasmidium. Helminthosporium has a wide distribution such as Asia (China (Taiwan), India, Japan, Pakistan, Russia), Caribbean (Cuba), Europe (Austria, Belarus, Italy, Poland, United Kingdom), New Zealand, North America (Canada), Union of Soviet Socialist Republics (USSR) and The United States (Alabama, Washington). Helminthosporium is known on many plants.
