Apple is a climacteric fruit of economic importance and high nutritional value. Better understanding of the apple ripening process is needed to improve fruit quality and extend apple shelf life. This paper presents the results of molecular cloning and characterization of a newly identified allele of the ripening-specific ACO1 gene from Malus floribunda 821. A polymorphism of the ACO1 gene was detected using the polymerase chain reaction and BamH1 and Rsal enzymatic digestion. Whilst cloning and sequencing data confirmed the identity of allele d, it also revealed high sequence conservation (97.3 to 98.9%). In addition, a comparison of sequence data revealed some differences within the coding regions of the ACO1 alleles identified so far.
