Importance and distribution

Quarantine significance

Stagonospora cirsii is a potential mycoherbicide of Cirsium arvense (Evidente et al. 2008). Stagonolides J and K and Stagochromene A, Chromene-4,5-dione isolated from Stagonospora cirsii S-47 is suggested for the biocontrol of Sonchus arvensis (Dalinova et al. 2019).

 

Biochemical importance of the genus, chemical diversity or applications

Stagonospora produces a wide range of compounds such as 6-methylsalicylic acid and (+)-epoxydon (Venkatasubbaiah et al. 1987), pramanicin, a modified acyltetramic acid (Bailey et al. 2000), stagonolide, phytotoxic nonenolide from Stagonospora cirsii (Yuzikhin et al. 2007), Stagonolides B-F, nonenolides (Evidente et al. 2008), fungal metabolites cercosporin, elsinochrome A and leptosphaerodione (Ahonsi et al. 2015), Trichopeptides A and B, trichocyclodipeptides A–C, peptides from the fungus Stagonospora trichophoricola (Chen et al. 2017), Chromene-4,5-dione, Stagochromene A, Stagonolides J and K (Dalinova et al. 2019).

 

There are 530 records of Stagonospora epithets in Index Fungorum (2022), but most of them have been transferred to other genera such as Allelochaeta, Ascochyta, Collonaemella, Didymella, Diplodina, Keissleriomyces, Kellermania, Kirramyces, Leptosphaeria, Longiseptatispora, Marssonina, Neosetophoma, Neottiosporina, Parastagonospora, Phomopsis, Placosphaerina, Septoria and Setoseptoria. Stagonospora consists of 289 species known on a wide range of hosts such as Amaranthaceae, Amaryllidaceae, Apocynaceae, Asteraceae, Caryophyllaceae, Cyperaceae, Fabaceae, Juncaceae, Malvaceae, Poaceae, Rosaceae and Simaroubaceae. Stagonospora has been reported from Asia (Armenia, India, Kazakhstan, Pakistan, Russian), Australia (New South Wales), Europe (Albania, Georgia, Kerguelen Islands), North America (Canada (Manitoba)) and the United States (North Carolina, North Dakota, Oklahoma, Wisconsin). DNA sequence data is essential to establish new species of Stagonospora because the genus is easily confused with other genera and the taxonomic placement is still complex.
