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.
