Importance and distribution

Species of Corynespora have diverse lifestyles. Most species are saprobic but Corynespora can infect a wide range of economically important crops such as cotton, soybean, tomato, and cucumber (Lopez et al. 2018; MacKenzie et al. 2018; Fernando et al. 2009). C. cassiicola causes a devastating disease on Hevea brasiliensis (Florence and Ebenezer 2018). Corynespora has been associated with human infection (Lopez et al. 2018). There are 208 Corynespora epithets in Index Fungorum (2022), but several species have been transferred to other genera such as Briansuttonia, Corynesporopsis, Helminthosporium, Morganjonesia, Passalora, Penzigomyces, Phaeoisariopsis, Solicorynespora and Vamsapriya. Corynespora comprises 175 species known on many host plants including Acacia pycnantha (Fabaceae), Acalypha hamiltonia (Euphorbiaceae), Achras sapota (Sapotaceae), Alstonia scholaris (Apocynaceae), Annona squamosa (Annonaceae), Celastrus buxifolius (Celastraceae), Cryptolepis buchananii (Apocynaceae), Gymnosporia buxifolia (Celastraceae), Vaccinium sp. (Ericaceae) and Vitex sp. (Lamiaceae). Corynespora has a wide distribution including Africa (Ghana), Asia (Brunei Darussalam, India, Indonesia (Java), Nepal, Philippines), Caribbean (Cuba), Europe (England, Turkey), North America (Canada), Oceania (Australia) and South America (Chile). Corynespora has a very high diversity of species but most species lack molecular data.


Industrial relevance and applications

Corynespora is useful to the medical industry in treatment of cancer as it produces chemical such as Depsidone which shows antitumor, antimicrobial and insecticidal activity (Okoye et al. 2013).


Biochemical importance of the genus, chemical diversity or applications

Corynespora produces a wide range of chemicals. Okoye et al. (2013) reported depsidone and diaryl ether derivatives from C. cassiicola. Corynespora can produce a host-selective protein toxin cassiicolin (Barthe et al. 2007). Ebrahim et al. (2013) reported an unusual octalactones from C. cassiicola. There is also report of microbial conversion of (±) Linalool to Linalool Oxides by C. cassiicola.
