Identification of a zinc transporter gene in strawberry.
We have cloned a ZRT (Zn-regulated transporter), IRT (Fe-regulated transporter)-like protein (ZIP) gene from the strawberry plant (Fragaria x ananassa Duch). This gene, designated as FaZIP1, is composed of three exons and two introns. The locations of the two introns (546 and 157 base pairs) in the gene were confirmed by sequence analysis of cDNA clones obtained by using 3' and 5' RNA ligase mediated-rapid amplification of cDNA ends (RLM-RACE) PCR. Also, based on the cDNA sequence, the transcriptional start site of FaZIP1 was assigned. FaZIP1 is predicted to code for a protein of 353 amino acids containing a signal peptide and eight potential transmembrane domains. Southern blot analysis indicated that FaZIP1 is a member of a multi-gene family. Reverse transcriptase-polymerase chain reaction (RT-PCR) analysis revealed that the FaZIP1 gene is constitutively expressed in strawberry leaves and roots.
