Y. Suzuki et al., Molecular cloning of vacuolar H+-pyrophosphatase and its expression duringthe development of pear fruit, PLANT CEL P, 40(8), 1999, pp. 900-904
The cDNA of vacuolar proton-translocating inorganic pyrophosphatase was clo
ned from pear fruit. It contained an open reading frame of 2,301 nucleotide
s, coding for a polypeptide of 767 amino acids. The level of mRNA was very
low in young fruit and increased with maturation, differing from the change
s in the level of polypeptide.
