Summary

Two homologous, nonallelic genes, ci21A and ci21B, were isolated and sequenced. Northern blot analysis showed that CI21 transcripts were present at the highest levels in cold-stored tubers, at lower levels in stems and roots, and at the lowest levels in leaves and tubers stored at room temperature. A 2-fold increase of beta-glucuronidase activity in response to tuber storage at 4 deg C was observed for fragments between 380 and 2000 bp of the ci21A promoter region.
