Abstract excerpt

PgiC, a complex gene with 23 coding exons and 22 intervening introns, encodes the cytosolic isozyme of phosphoglucose isomerase (EC 5.3.1.9) in higher plants. Here, we report RNA ligase-mediated rapid amplification of cDNA ends experiments that showed that PgiC in Clarkia (Onagraceae) and Arabidopsis thaliana has an intron in the 5' leader. Comparison of the EMBL accessions of the cDNA and genomic sequences...
