Clonostachys rosea f. rosea, also known as Gliocladium roseum,[1] is a species of fungus in the family Bionectriaceae. It colonizes living plants as an endophyte, digests material in soil as a saprophyte and is also known as a parasite of other fungi and of nematodes.[2] It produces a wide range of volatile organic compounds which are toxic to organisms including other fungi, bacteria, and insects, and is of interest as a biological pest control agent.
Biological control
Clonostachys rosea protects plants against Botrytis cinerea ("grey mold") by suppressing spore production.[3] Its hyphae have been found to coil around, penetrate, and grow inside the hyphae and conidia of B. cinerea.[4]
Nematodes are infected by C. rosea when the fungus' conidia attach to their cuticle and germinate, going on to produce germ tubes which penetrate the host's body and kill it.[3]
Biofuels
In 2008 an isolate of Clonostachys rosea (NRRL 50072) was identified as producing a series of volatile compounds that are similar to some existing fuels, including diesel. However, the taxonomy of this isolate was later revised to Ascocoryne sarcoides.[5]
