The suppressor of forked mutation in Drosophila melanogaster: interactions with the lozenge gene

An interaction between the lozenge gene and the suppressor of forked gene of Drosophila melanogaster has been investigated both spectrophotometrically and electrophoretically. The nature of this interaction is such that certain lozenge alleles appear to be phenotypically suppressed while others are enhanced or unaffected, and the results reported demonstrate that the effect can clearly be observed at the biochemical level. Earlier observation have suggested that the suppressor of forked gene codes for a ribosomal protein, and this hypothesis is discussed.
