✦ Synopsis

Eight methionine loci in AspergiUus nidulans were found. Their metabolic blocks and localization were determined. The spontaneous reversion rates for different methionine loci were studied. The revertants were all of suppressor type unlinked or loosely linked with methionine loci. There are at least 8 different suppressor loci. The suppressor mutations are recessive or partly dominant and many of them are quite unspecific, acting on all methionine loci even on those with different metabolic blocks.
