“…Deep pigmentations during late incubation periods of C. militaris could be due to different phases of photoinduced carotenogenesis such as light reaction, protein synthesis and accumulation of carotenoid pigments (Harding and Shropshire, 1980). Friederichsen and Engel (1958) reported carotenoid as the compound, which produces orange color of C. militaris .…”

Observations on Some of the Mycelial Growth and Pigmentation Characteristics ofCordyceps militarisIsolates

et al. 2006

Characteristic growth patterns of Cordyceps militaris isolates on various media, under varying light conditions and at varying incubation periods were examined. Light was found to be the most critical single factor in determining the density, texture, and pigmentation of the mycelial culture of the fungus. However, under the light condition, the degree of pigmentation and mycelial density were found to be affected by the incubation period and type of medium. Irrespective of the variations in medium type or incubation period, there was no pigmentation of the mycelium under dark condition. Radial growth of the mycelium was faster under dark incubation rather than under light incubation. Abundant mycelial density and darkest pigmentation of C. militaris isolates were produced in nutritionally rich media like SDAY, SMAY and CZYA, suggesting that these media may fulfill all the requirements for vegetative growth of the fungus. Growth characteristics of C. militaris isolates could be easily observed by the simple agar culture method, which would be useful to characterize the phenotypic characteristics of large number of pure cultures of the fungus under given conditions of growth factors such as medium, light and temperature.

“…Other characters of C. militaris isolates such as mycelial texture (cottony or non-cottony) or growth rate were not found to be suitable since most of the isolates were non-cottony and uniform in growth rate. The orange pigmentation of C. militaris has been reported to be due to the presence of carotenoid (Friederichsen and Engel, 1958). A number of fungal mutants affected in carotenoid biosynthesis have been isolated, with those of Phycomyces blakesleeanus being the most widely studied (Fraser et al, 1996).…”

Genetic Analysis of Pigmentation inCordyceps militaris

Pigmentation of ascospore-derived isolates from seven different natural specimens of Cordyceps militaris EFCC C-5888, EFCC C-7159, EFCC C-7833, EFCC C-7991, EFCC C-8021, EFCC C-8023 and EFCC C-8179 was observed on the plates of Sabouraud Dextrose agar plus Yeast Extract at 25℃ under continuous illumination (500 lux). Pigmentation of the wild-type isolates of C. militaris was diverse ranging from yellowish white to orange, while white color was believed as a mutant. Inheritance of pigmentation was found to be controlled by both parental isolates when F1 progeny were analyzed. Pigmentation and mating type were shown to be either independent or distantly linked each other due to the high percentage of non-parental phenotypes among F1 progeny. Crosses between white mutant isolates of C. militaris yielded progeny with wild type pigmentations, indicating that the albino mutations in the parents were unlinked to each other.

“…Similarly, C. militaris produces pigments that make it yellow or orange (Yang et al, 2016). The pigments contained in C. militaris were first considered to be carotenoids and water-soluble (Friederichsen and Engel, 1958). In 2013, four novel water-soluble carotenoids were isolated and identified from C. militaris (Dong et al, 2013b).…”

Transcriptome Analysis of Cordyceps militaris Reveals Genes Associated With Carotenoid Synthesis and Identification of the Function of the Cmtns Gene

et al. 2019

Cordyceps militaris, a valuable edible and medicinal fungus, has attracted increasing attention because of its various bioactive ingredients. However, the biosynthetic pathway of C. militaris carotenoids is still unknown due to lack of transcriptome information. To uncover genes related to the biosynthesis of C. militaris carotenoids, the transcriptomes of mycelia CM10_D cultured under dark conditions and mycelia CM10_L cultured under light exposure conditions were sequenced. Compared with mycelia CM10_D, 866 up-regulated genes and 856 down-regulated genes were found in mycelia CM10_L. Gene ontology (GO) analysis of differentially expressed genes (DEGs) indicated that DEGs were mainly classified into the “metabolic process,” “membrane,” and “catalytic activity” terms. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of DEGs suggested that DEGs were mainly enriched in “metabolic pathways,” “MAPK signaling pathway-yeast,” and “biosynthesis of secondary metabolites.” In addition, the carotenoid content of the Cmtns gene deletion mutant (ΔCmtns) was significantly lower than that of the wild-type C. militaris CM10, while the carotenoid content of the complementary strain (ΔCmtns-c) of the Cmtns gene was not significantly different from that of C. militaris CM10, suggesting that the Cmtns gene significantly affected the biosynthesis of carotenoids in C. militaris. These results potentially pave the way for revealing the biosynthetic pathway of carotenoids and improving carotenoids production in C. militaris.
