Characterization of duplicated two cytosolic phosphoglucose isomerase (PgiC) loci in Arabidopsis halleri ssp. gemmifera.
Arabidopsis halleri ssp. gemmifera has two cytosolic phosphoglucose isomerase (PgiC) loci. A 48-bp deletion was observed in the junction of exon 17 and intron 17 for a locus (PgiC2). PCR-RFLP analysis using cDNA template did not detect the PgiC2 locus. Another locus (PgiC1) has common structure with A. thaliana and expressed normally. A phylogenetic tree of PgiC sequences revealed that duplication of the two loci in A. gemmifera occurred after species splitting of A. thaliana and A. gemmifera. More than 12 kb region encompassing PgiC was sequenced for both loci. In both PgiC1 and PgiC2, sequence homologous to A. thaliana PgiC 5' upstream region was not detected. A gene located on chromosome 4 of A. thaliana was detected in the 5' upstream of PgiC2. This result suggested that the microsyntheny around the PgiC region between A. thaliana and A. gemmifera is not established.
