Abstract

The vestigial (Vg) mutant is a Z-linked mutant that causes vestigial wings in the silkworm, Bombyx mori. We have previously reported a 1.5-Mb interstitial deletion on the Z chromosome bearing the Vg mutation (ZVg chromosome). In this study, we found that exons 3-8 of a gene named Bmptp-Z encoding a putative tyrosine-specific protein phosphatase are deleted by the 1.5-Mb interstitial deletion. We found that a gene encoding the Bombyx homolog of Drosophila Apterous (BmAp-A) protein is located 4.5 kb downstream of the distal breakpoint of the 1.5-Mb interstitial deletion. Moreover, an in-frame fusion transcript composed of the 5' part of Bmptp-Z and the 3' part of Bmap-A is generated specific to the ZVg chromosome. Effects of the in-frame fusion transcript on the vestigial phenotype are discussed.
