Cordyceps sensu lato is a genus of arthropod-pathogenic fungi, which have been used traditionally as medicinal in Asia. Within the genus, Ophiocordyceps sinensis is the most coveted and expensive species in China. Nevertheless, harvesting wild specimens has become a challenge given that natural populations of the fungus are decreasing and because large-scale culture of it has not yet been achieved. The worldwide demand for products derived from cultivable fungal species with medicinal properties has increased recently...

As the major active ingredient of Cordyceps militaris, cordycepin (3'-deoxyadenosine) has been well documented to alleviate inflammation and oxidative stress both in vitro and in vivo. To explore the potential protective effect of cordycepin in fulminant hepatic failure, mice were pretreated with cordycepin for 3 weeks followed by D-galactosamine (GalN)/lipopolysaccharide (LPS) injection. Then we found cordycepin (200 mg/kg) administration elevated survival rate, improved liver function, and suppressed hepatocyte apoptosis and necrosis in mice with severe hepatic damage by GalN/LPS treatment...

Cordyceps militaris, a member of Ascomycota, a mushroom referred to as caterpillar Dong-chung-ha-cho, is commercially valuable because of its high content of bioactive substances including cordycepin and its potential for artificial cultivation. Cordycepin (3'-deoxyadenosine) is highly associated with the pharmacological effects of C. militaris. C. militaris is heterothallic in that two mating type loci, idiomorph MAT1-1 and MAT1-2, exist discretely in two different spores. In this study, nine C. militaris strains were mated with each other to prepare new strains that produced a larger amount of cordycepin than the parent strains...

Light is a necessary environmental factor for production of conidia and pigment, formation of stroma, and development of Cordyceps militaris, a well-known edible and medicinal mushroom. In this study, an obvious rhythm loop was observed in certain strains of C. militaris under conditions of alternating 12-hour intervals of dark and light. A possibly related gene, Cmvvd, the homologue of the blue-light photoreceptor of Neurospora crassa, was cloned from the genome of C. militaris. The protein CmVVD is predicted to be 203 amino acids in length and is characterized by the presence of a light, oxygen, or voltage domain...

Cordyceps militaris, known as Dong-Chong-Xia-Cao, produces the most cordycepin among Cordyceps species and can be cultured artificially. For these reasons, C. militaris is widely used as herb or functional food in the East Asia. In this study, we developed a new strain of C. militaris that produces higher cordycepin content than parent strains through mating-based sexual reproduction. Twenty parent strains were collected and identified as C. militaris based on internal trasncrived spacer and rDNA sequences...

Cryptochromes (CRYs) belong to the photolyase/cryptochrome flavoprotein family, which is widely distributed in all kingdoms. A phylogenetic analysis indicated that three Cordyceps militaris proteins [i.e., cryptochrome DASH (CmCRY-DASH), (6-4) photolyase, and cyclobutane pyrimidine dimer (CPD) class I photolyase] belong to separate fungal photolyase/cryptochrome subfamilies. CmCRY-DASH consists of DNA photolyase and flavin adenine dinucleotide-binding domains, with RGG repeats in a C-terminal extension. Considerably, more carotenoids and cordycepin accumulated in the ΔCmcry-DASH strain than in the wild-type or ΔCmwc-1 strains, indicating an inhibitory role for CmCRY-DASH in these biosynthetic pathways...

Verticillin is one of the dimeric epipolythiodioxopiperazines (ETPs) which are toxic secondary metabolites produced only by fungi. ETPs have received substantial attention since its complex molecular architecture and a wide range of biological activities. Although biosynthesis of the monomeric gliotoxin has been studied extensively, the biosynthetic pathway of dimeric ETPs is far from being studied. To investigate the biosynthesis of dimeric ETPs and expand our understanding of their dimerization, the verticillin biosynthetic gene cluster (ver) was identified and cloned from a genomic DNA fosmid library of the Cordyceps-colonizing fungus Clonostachys rogersoniana with the designed primers based on the sequence of a nonribosomal peptide synthetase (NRPS) ChaP which was predicted to be responsible for chaetocin biosynthesis in Chaetomium virescens...
