Importance and role
Importance of genus to ecosystem
Species of Microcyclospora are saprobic and play a role in nutrient recycling within the ecosystem. Some species are pathogenic and cause wilts, leaf spots, such as leaf spot blueberry diseases (James 2017) and sooty blotches on various hosts.
Industrial relevance and applications
Microcyclospora are useful in agricultural industry as they produce obionin A which has cytotoxic effects and antifungal activities (Surup et al. 2015).
M. malicola has biocontrol property against the anthracnose fungus Colletotrichum fioriniae (Surup et al. 2015). M. malicola also exhibit activity against filamentous fungus Mucor hiemalis and gram-positive bacterium Bacillus subtilis (Surup et al. 2015).
Biochemical importance of the genus, chemical diversity or applications
Microcyclospora produces various chemical compounds. Some of them are obionin A (Surup et al. 2015), trichothecolone acetate and the derivative (S)-7-hydroxytrichothecolone (Surup et al. 2014).
Diversity of the genus
Microcyclospora comprises five species known on three different host plants and plant families namely Anacardiaceae, Fagaceae and Rosaceae. One species M. rumicis has been synonymized and transferred to another genus Sphaerulina. Microcyclospora has been reported mainly from Germany, Netherlands, Ontario and Slovenia. Microcyclospora seems to have a wide host and geographical distribution. More species of Microcyclospora can be discovered in future studies.
