1.16.1.7 a yeast Fe3+ chelate-reductase gene is fused to the promoter of the Fe-regulated transporter and introduced into rice plants using Agrobacterium tumefaciens 1.16.1.7 DNA and amino acid sequence determination and analysis, single strand confirmation polymorphism analysis, overview 1.16.1.7 expressed as AhFRO1-GFP fusion protein in epidermal cells of Allium cepa 1.16.1.7 expressed in Saccharomyces cerevisiae strain BJ2168 1.16.1.7 expression in Escherichia coli, infecting tomato roots with the satellite DNAmbeta and cognate virus using Agrobacterium tumefaciens 1.16.1.7 expression of ferric reductase oxidase FRO6-GFP or FRO7-GFP in yeast 1.16.1.7 expression the gene AtFRO6 under the control of a 35S promoter in transgenic Nicotiana tabacum cv. Xanthi plants using the Agrobacterium tumefaciens strain EHA105 for transfection. Ferric reductase activity in leaves of transgenic plants grown under iron-sufficient or iron-deficient conditions is 2.13 and 1.26fold higher than in control plants, respectively. Light-responsive elements within the FRO6 promoter regionmediate gene activation on exposure to light 1.16.1.7 gene FRO1, DNA and amino acid sequence determination and analysis, phylogenetic tree, expression analysis under iron deficient and control conditions 1.16.1.7 gene FRO2, DNA and amino acid sequence determination and analysis, phylogenetic tree, expression analysis under iron deficient and control conditions 1.16.1.7 gene LeFRO1, DNA and amino acid sequence determination and analysis from 16 different cultivars, genotyping detects three types of LeFRO1 (LeFRO1MM, LeFRO1Ailsa and LeFRO1Monita) with five amino acid variations at the positions 21, 24, 112, 195 and 582
