A Fairy Chemical, Imidazole-4-carboxamide, is Produced on a Novel Purine Metabolic Pathway in Rice.

ABSTRACT: Rings or arcs of fungus-regulated plant growth occurring on the floor of woodlands and grasslands are commonly called "fairy rings". Fairy chemicals, 2-azahypoxanthine (AHX), imidazole-4-carboxamide (ICA), and 2-aza-8-oxohypoxanthine (AOH), are plant growth regulators involved in the phenomenon. The endogeny and biosynthetic pathways of AHX and AOH in plants have already been proven, however, those of ICA have remained unclear. We developed a high-sensitivity detection method for FCs including ICA and the endogenous ICA was detected in some plants for the first time. The quantitative analysis of the endogenous level of ICA in rice and Arabidopsis were performed using ¹³C-double labeled ICA. In addition, the incorporation experiment and enzyme assay using the labeled compound int
