生氰植物和真菌在自然界中广泛存在。虽然氢氰酸在植物中的起源已被详细研究，但对其在真菌中的起源知之甚少。在这里，我们报告的乙醛酸氰醇作为前体的氢氰酸在真菌小皮伞和其他几个产氰真菌的鉴定。此外，喂养实验揭示甘氨酸作为乙醛酸的氰醇的生物合成前体。因此，M. oreades和其他真菌与植物中的氰生成根本不同。
Cyanogenic plants and fungi are widespread in nature. Although the origin of hydrocyanic acid in plants has been studied in detail, little is known about its origin in fungi. Here, we report the identification of the cyanohydrin of glyoxylic acid as the precursor of hydrocyanic acid in the fungus Marasmius oreades and several other cyanogenic fungi. Moreover, a feeding experiment revealed glycine as biosynthetic precursor of the cyanohydrin of glyoxylic acid. Thus, the cyanogenesis of M. oreades and other fungi is fundamentally different from cyanogenesis in plants.
