These results indicate that alterations of the wing by inhibitors of dTMP synthesis are caused by an effect of these drugs on levels of vg transcripts; the resistance to such agents observed for the vgBG strain is not due to a qualitatively different effect of this drug on the vg transcript but, rather, is related to the expression of a modified Vg protein encoded by a truncated transcript. Fruit flies have dominant and recessive traits, which are based on the combination of alleles received from their parents. … Search for more papers by this author.

In this paper, we show that: (1) depletion of the dTMP pool by aminopterin leads to a decrease in the amount of vg transcripts; (2) insertion of the retrotransposon 412 in the vgBG mutant, which is resistant to aminopterin, leads to the formation of a truncated transcript that is prematurely terminated in the long terminal repeat of this transposable element; and (3) aminopterin also affects the level of this truncated transcript.

The mutationsvestigial (vg; recessive) andUltravestigial (vg U; dominant) ofDrosophila melanogaster give rise to identical mutant adult phenotypes in which much of the cases this results from cell death in the presumptive wing margin of the wing disc in the third larval instar, but the process of cell degeneration is quite different in the two mutants.
