Figure 1From: Regulation of Zn and Fe transporters by the GPC1gene during early wheat monocarpic senescenceBiosynthesis of mugienic acid phytosiderophores. The combination of three molecules of SAM to form one molecule of NA is catalyzed by NAS. NA is converted to DMA through the action of NAAT to form a 3”-keto intermediate and then by DMAS to form DMA. Adapted from Bashir et al. [26].Back to article page
