The vestigial (vg) gene mutations of D. melanogaster induced by HHP treatment.
(a) The transversion from C to T at nucleotide 1892 in complete cDNAs of vg gene. (b) The transversion from G to A at nucleotide 2129 in complete cDNAs of vg gene. (c) The four bases deletion (TGGC) spanning from nucleotide 1739 to 1742 in complete cDNAs of vg gene. (d) An insertion sequence with 12 nucleotides (5ā²-CTCGCCCTGTCT -3ā²) between the second and third exons of vg. Co denotes control; F1, F2, F3 and F4 represent first, second, third and fourth generation mutants, respectively.
