Genetic Analysis of Pigmentation in Cordyceps militaris

초록

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 Sab- ouraud Dextrose agar plus Yeast Extract at 25 oC under continuous illumination (500 lux). Pigmentation of the wild-type iso- lates of C. militaris was diverse ranging from yelowish 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. Pig-mentation and mating type were shown to be either independent or distantly linked each other due to the high percentage C. militaris yielded progeny with wild type igmentations, indicating that the albino mutations in the parents were unlinked to each other.
