2-Azahypoxanthine (AHX, 1) and imidazole-4-carboxamide (ICA, 2) were isolated from a fairy-ring-forming fungus Lepista sordida. AHX was converted into a metabolite 2-aza-8-oxo-hypoxanthine (AOH, 3) in plants. It was found out that these three compounds, named as fairy chemicals (FCs), endogenously exist in plants and are biosynthesized via a new purine metabolic pathway. FCs provided tolerance to the plants against various stresses and regulated the growth of all the plants. In addition, FCs increased the yield of rice, wheat, and other crops in the greenhouse and/or field experiments.

童话化学品是植物激素的新家族吗？

从形成仙环的真菌Lepista sordida中分离出2-氮杂黄嘌呤（AHX，1）和咪唑-4-羧酰胺（ICA，2）。AHX在植物中转化为代谢物2-氮杂8-氧代次黄嘌呤（AOH，3）。发现这三种化合物，称为仙女化学物质（FCs），是内源存在于植物中，并通过新的嘌呤代谢途径进行生物合成。FCs为植物提供了对各种胁迫的耐受性并调节了所有植物的生长。此外，在温室和/或田间试验中，FCs提高了水稻，小麦和其他农作物的产量。
