Abstract
Using disc electrophoresis, a new zone of acid phosphatase activity (ACP-I) was identified in apple.
This zone migrates faster than the other zones and shows activity only in the cotyledons.
The examination of electrophoretic phenotypes in progenies showed that a gene ACP-1 is responsible for activity in this zone.
Two alleles were identified, responsible for the activity of the fast and slow band.
In addition, a null allele was identified. ACP-1 appears to be closely linked (r = 0.08±0.030) with the pale green lethal gene 1. A gene controlling endopeptidase activity, ENP-1 was also found to be linked with 1 (0.07±0.028). The order of linkage of the three genes was determined (ACP-1 – ENP-1 – 1). The activity of ACP-1, in the early stages of plant development, only in the cotyledons, suggests a specific role for this isoenzyme.
