Scientists cloned and studied a gene called PAL in the winter mushroom (Flammulina velutipes), which produces trans-cinnamic acid from phenylalanine. They found that this gene is activated differently depending on the nutrient environment and mushroom developmental stage. The gene is particularly active in the mushroom’s stem during growth, suggesting it helps produce beneficial compounds during mushroom development.

Mushrooms Do Produce Flavonoids: Metabolite Profiling and Transcriptome Analysis of Flavonoid Synthesis in the Medicinal Mushroom Sanghuangporus baumii

Researchers discovered that the medicinal mushroom Sanghuangporus baumii produces 81 different flavonoids, compounds known for their health benefits including antioxidant and anti-cancer properties. Using advanced genetic and chemical analysis, they identified the genes and processes responsible for this flavonoid production in mushrooms, which differs from how plants make these compounds. By increasing the activity of a key gene called PAL, they were able to boost flavonoid production in the mushroom. This discovery opens new possibilities for using mushrooms as biological factories to produce flavonoids for medical and nutritional applications.
