A computer search has not revealed the pres-
ence of the E8/E4 consensus protein recognition
site in the 1.45 kb PG promoter upstream of the
transcription start site and there were no other
significant sequence homologies apart from vari-
able stretches of A/T-rich sequences between the
flanking sequences of the E8 or E4 fruit ripening
genes and the PG promoter (J. Shabbeer, unpub-
lished results)
