Mannitol mediates the mummification behavior of larvae infected with .

Introduction: Parasites can facilitate their own spread and reproduction by manipulating insect hosts behavior, as seen in the interaction between and . Infection by leads to the mummification of larvae, but the underlying mechanisms remain mysterious.

Methods: The morphology of infected larvae and fungal growth were first observed.

Neurotransmitter acetylcholine mediates the mummification of -infected larvae.

Parasites can manipulate host behavior to facilitate parasite transmission. One such host-pathogen interaction occurs between the fungus and the ghost moth is involved in the mummification process of infected host larvae. However, the underlying molecular and chemical mechanism for this phenomenon is unknown.

Stable reference gene selection for Ophiocordyceps sinensis gene expression studies under different developmental stages and light-induced conditions.

The molecular mechanism of Chinese cordyceps formation has received a substantial amount of attention because of its usage as traditional Chinese medicine. The formation process of Chinese cordyceps includes two parts: asexual proliferation (Ophiocordyceps sinensis proliferates in the hemolymph of Thitarodes armoricanus larvae) and sexual development (formation and development of fruiting bodies). Therefore, validation of reference genes under different development stages and experimental conditions is crucial for RT-qPCR analysis.

Determination of myriocin in natural and cultured Cordyceps cicadae using 9-fluorenylmethyl chloroformate derivatization and high-performance liquid chromatography with UV-detection.

A simple and sensitive reversed-phase liquid chromatographic method, based on the precolumn derivatization with 9-fluorenylmethyl chloroformate, was developed for the determination of myriocin. The derivatization reaction was performed in organic solvents of pyridine and tetrahydrofuran at 40 degrees C. Several factors influencing the derivative yield were investigated and optimized.

Hyperproduction of cordycepin by two-stage dissolved oxygen control in submerged cultivation of medicinal mushroom Cordyceps militaris in bioreactors.

Effect of oxygen supply on cordycepin production was investigated in submerged cultivation of Cordyceps militaris, a famous traditional Chinese medicinal mushroom, in a 5-L turbine-agitated bioreactor (TAB). Initial volumetric oxygen transfer coefficient (kLa) within the range of 11.5-113.
