Dear Dr. Yamamoto, I am writing about your lingerer line which you wrote about in \*x FBrf0092235 == Kuniyoshi and Yamamoto, 1997, A. Conf. Dros. Res. 38: 220B I have come across it as part of an editing job that I am currently engaged in, and I wonder whether you have a symbol for the insertion allele yet, also which P element has inserted in the allele? Many thanks for your help, Rachel. \--------------------------------------------------------------------- Rachel Drysdale. FlyBase (Cambridge), \--------------------------------------------------------------------- > Subject: lingerer Dear Rachel, We call the P-element induced allele lingerer<P1>. The abbreviated symbol is lig<P1>. The P-element inserted is Bm delta-w. A brief description about the lig mutation has been given in my review article appeared in Annu. Rev. Entomol. 42:551-585 . Hope this information is useful for you. Best wishes, Daisuke \------------------------------------------------------ YAMAMOTO, Daisuke ERATO, Mitsubishi-Kasei Institute of Life Sciences, Minami-Ooya 11, 194 Machida-shi, Tokyo, Japan \------------------------------------------------------
