SummaryFive X-linked, recessive alleles were isolated which suppress both the pupal and adult coloration phenotypes of the black mutation. Electron micrographs of shed puparia revealed that the aberrant sclerotization of the black cuticle is also suppressed. Amino acid analysis indicated that suppression is associated with an increased concentration of β-alanine, an amino acid known to be deficient in black. The suppressor locus mapped at the tip of the X, to the right of scute, and intragenic… Expand

The dominant mutation Suppressor of black indicates that de novo pyrimidine biosynthesis is involved in the Drosophila tan pigmentation pathway
It is proposed that diminished end-product inhibition of de novo p Skyrimidine biosynthesis in Su(b) flies increases available pyrimidine and consequently the β-alanine pool. Expand
The physiological effects of dumpy mutations on de‐novo pyrimidine synthesis in Drosophila melanogaster
Results accumulate to support the theory that dp might have some regulatory effect on the pyrimidine synthesis which might be caused by an alteration in the chitin synthesis. Expand
Mutations affecting phenol oxidase activity inDrosophila: quicksilver andtyrosinase-1
The diphenol oxidase activity in double mutant combinations shows that these mutations and Dox-A2 (Pentzet al., 1986) affect this enzyme in different ways. Expand


6-Azauracil induced phenocopies of rudimentary wing mutants and their suppression by a suppressor mutant of rudimentary in Drosophila melanogaster.
It is concluded that the induced wing defects are true phenocopies of rudimentary wings and provide additional evidence for a deficient pyrimidine biosynthesis in rudimentary mutants and encourage the use of antimetabolites in the biochemical investigation of morphological mutants of Drosophila.

Flies which do not fail to incorporate injected beta-alanine into developing cuticles, but which exhibit inhibited beta-Alanine synthesis (flies homozygous for the gene ‘b’) are not only protected, as pupae, from ultraviolet damage by beta- Alanine injection but also show enhanced mating success when injected as newly emerged adults.

Microinjection of 1- 14 C- β -alanine into immobile larvae at spiracle eversion confirmed that this substance is utilized during tanning of the pupal case in Drosophila melanogaster, and it is improbable that the abnormalities observed in thevisual behaviour of this mutant can be ascribed to excess β-alanine.

Beta-Alanine Utilization of Ebony and Non-ebony Drosophila melanogaster
Carbon-14-labeled β-alanine was injected into newly formed Drosophila melanogaster female pupae. Homozygous ebony deposited less C14in pupal sheaths, deposited more C14in adult body extracts andExpand
β Alanine and cuticle maturation in Drosophila
THE sclerotisation and tanning of insect cuticles is generally thought to result from a crosslinking of the cuticular proteins by quinonoid derivatives of tyrosine1,2. Little consideration has beenExpand

Abstract Microinjection of radioactive tyrosine, dopa, and dopamine into mature larvae of Drosophila revealed that the sclerotization pathway is similar but not identical to that in Calliphora : (a)Expand

Beta-Alanine metabolism in the housefly, Musca domestica: studies on anabolism in the early puparium.
β-Alanine synthesis has been studied in the housefly, Musca domestica and it was found by radioassay that relative to the other compounds tested uracil contributed 56·2 per cent and aspartate 24·2per cent, while pantothenate, propionate, and malonate contributed 9·4, 7·1, and 3·1 per cent, respectively.
