Pyrus betulifolia Bunge belongs to the woody plant family and is an ideal model for studying molecular strategies of iron acquisition and metabolism in strategy I plants. Using polymerase chain reaction amplification technology, a gene encoding a putative ferric chelate reductase (FCR) protein was isolated from P. betulifolia and designated as PbFRO2. This gene was 2166 bp in length with an open reading frame encoding a protein of 721 amino acids. A hidden Markov model for topology prediction of PbFRO2 suggested that there were 10 transmembrane regions (I-X) connected by nine loops. Phylogenetic analyses demonstrated that PbFRO2 had the highest homology with Malus xiaojinensis Cheng & Jiang. Iron starvation induced significant increase in root FCR activity and PbFRO2 expression. The split-root experiment demonstrated that Fe limitation in one portion of the root system triggered significant up-regulation of the PbFRO2 expression in the Fe-sufficient part, suggesting that the PbFRO2 expression was induced by systemic signals. Furthermore, the addition of a-naphthaleneacetic acid was found to strengthen the Fe deficiency-caused up-regulation of the PbFRO2 expression in the roots. By contrast, 1-naphthylphthalamic acid application blocked up-regulation of the PbFRO2 expression. The results indicated that Fe deficiency-induced alterations of the PbFRO2 expression were mediated by auxin.
