Secrets of Flavonoid Synthesis in Mushroom Cells

Flavonoids are chemical compounds that occur widely across the plant kingdom. They are considered valuable food additives with pro-health properties, and their sources have also been identified in other kingdoms. Especially interesting is the ability of edible mushrooms to synthesize flavonoids. Mushrooms are usually defined as a group of fungal species capable of producing macroscopic fruiting bodies, and there are many articles considering the content of flavonoids in this group of fungi. Whereas the synthesis of flavonoids was revealed in mycelial cells, the ability of mushroom fruiting bodies to produce flavonoids does not seem to be clearly resolved. This article, as an overview of the latest key scientific findings on flavonoids in mushrooms, outlines and organizes the current state of knowledge on the ability of mushroom fruiting bodies to synthesize this important group of compounds for vital processes. Putting the puzzle of the current state of knowledge on flavonoid biosynthesis in mushroom cells together, we propose a universal scheme of studies to unambiguously decide whether the fruiting bodies of individual mushrooms are capable of synthesizing flavonoids.

Automated summary

Flavonoids are widely distributed chemical compounds found in plants and other kingdoms, and mushrooms have the ability to synthesize these compounds. However, it is not clear whether mushroom fruiting bodies can produce flavonoids. This article provides an overview of the research on flavonoids in mushrooms and proposes a research scheme to determine the synthesis ability of flavonoids in mushroom fruiting bodies.
