Molecular and biochemical characterization of the Fe(III) chelate reductase gene family in Arabidopsis thaliana. Wu H, Li L, Du J, Yuan Y, Cheng X, Ling HQ. Plant Cell Physiol. 2005 Sep;46(9):1505-14. ...... activity among the AtFROs investigated, further demonstrating that AtFRO2 is a major iron reductase gene in Arabidopsis. AtFRO2 and AtFRO3 were mainly expressed in roots of Arabidopsis, AtFRO5 and AtFRO6 in shoots and flowers, and AtFRO7 in cotyledons and trichomes, whereas the transcription of AtFRO8 was specific for leaf veins. Considering the tissue-specific expression profiles of AtFRO genes, we suggest that AtFRO2 and AtFRO3 are two Fe(III) chelate reductases mainly ...... |
