| Abstract: | When labeled 1-aminocyclopropane-1-carboxylic acid, an ethylene precursor, was administered to light-grown wheat leaves, it was primarily converted into a nonvolatile metabolite, which was identified as 1-(malonylamino)cyclopropane-1-carboxylic acid. The natural occurrence of this conjugate in the wilted wheat leaves was confirmed by gas chromatography-mass spectrometry. |
