Summary

Variations in content and/or availability of the amino acids methionine, cysteine, arginine, leucine, and histidine in the apple varieties, Jonathan, McIntosh, Red Delicious, and Golden Delicious influence the fruit's susceptibility to amino acid-dependent mutants ofPenicillium expansum. Differences among these varieties in the levels of several vitamins, or of the purines, adenine, or hypoxanthine, do not alter susceptibility. The growth in vitro of 7 arginine-requiring mutants at 1×10−4 M arginine and the decay they cause in apples were directly correlated.
