Construction of a genetic linkage map and detection of quantitative trait locus for the ergothioneine content in tamogitake mushroom (Pleurotus cornucopiae var. citrinopileatus)

Researchers created the first genetic map of tamogitake mushrooms to identify genes controlling ergothioneine content. Ergothioneine is an antioxidant compound that provides health benefits like fighting inflammation and protecting brain health. They found one key genetic marker that reliably predicts which mushrooms will have high ergothioneine levels, enabling farmers to selectively breed mushrooms with enhanced health benefits.
