Ergothioneine accumulation in a medicinal plant Gastrodia elata

Ergothioneine (ERG) has long been recognized as a potent and stable antioxidant. In nature, ERG is synthesized only in fungi and mycobacteria, not in plants. The lifecycle of Gastrodia elata, an achlorophyllous orchid plant, is completely dependent on the presence of symbiotic fungi, particularly Armillaria mellea. In this study, we report for the first time that G. elata accumulated ERG whose levels...
