Graminaceous plants have evolved a unique mechanism to acquire iron through the secretion of family small molecules, called mugineic acid phytosiderophores (MAs). All MAs are synthesized from l-Met, sharing same pathway l-Met 2'-deoxymugineic (DMA). DMA is reduction 3''-keto intermediate by deoxymugineic synthase (DMAS). We isolated DMAS genes rice (OsDMAS1), barley (HvDMAS1), wheat (TaD-MAS1), and maize (ZmDMAS1). Their nucleotide sequences indicate that OsDMAS1 encodes predicted...

Iron deficiency is one of the major agricultural problems, as 30% arable land world too alkaline for optimal crop production, rendering plants short available iron despite its abundance. To take up apoplasmic precipitated iron, secrete phenolics such protocatechuic acid (PCA) and caffeic acid. The molecular pathways genes uptake strategies are already characterized, whereas mechanisms synthesis secretion have not been clarified, no efflux transporters identified in yet. Here we describe...

Zinc (Zn) is an essential micronutrient with numerous cellular functions in plants, and its deficiency represents one of the most serious problems human nutrition worldwide. Zn causes a decrease plant growth yield. On other hand, could be toxic if excess amounts are accumulated. Therefore, uptake transport must strictly regulated. In this review, dominant fluxes soil–root–shoot translocation rice plants (Oryza sativa) described, including from soils form Zn2+ Zn-DMA at root surface, to...

Iron (Fe) is an essential micronutrient for plants; however, despite its abundance in soils it not readily available neutral to alkaline soils. Plants secrete phenolics, such as protocatechuic acid (PCA) and caffeic (CA), absorb utilize precipitated apoplasmic Fe from root surfaces. However, the synthesis secretion of phenolics have been well characterized plants. We identified a rice (Oryza sativa L.) mutant with reduced amounts PCA CA xylem sap exudates; hence we named efflux zero 2...
