Subject: ADRC: 236B Dear Vladic, I am writing in connection with your abstract for the upcoming Washington DC ADRC: 'Maternal products of two new genes, rasp and grater, are required for the segmentation of the Drosophila embryo.' You describe two genes rsp and grr, that are new to FlyBase. Do you have map locations for these genes? It is nice if we can keep as many gene records anchored to the map as possible. Thank you for your help, with best wishes, Rachel. Subject: Re: 39th ADRC: 236B Dear Rachel, In the abstract 236B for the 1998 Drosophila Meeting I described two new genes, rasp (rsp), and grater (grr). grater (grr) is located between 068A02-03 and 068B01-03 This location is based on the following complementation tests: non-complementing deficiencies: Df(3L)lxd6 Breakpoints: 067E01-02;068C01-02 Df(3L)vin2 Breakpoints: 067F02-03;068D06 Df(3L)vin5 Breakpoints: 068A02-03;069A01-03 complementing deficiencies: Df(3L)vin4 Breakpoints: 068B01-03;068F03-06 Df(3L)vin7 Breakpoints: 068C08-11;069B04-05 So, in the 'FlyBase format' the location can be specified as follows: Left limit from inclusion within Df(3L)vin5 (FBab0002457) Right limit from non-inclusion within Df(3L)vin4 (FBab0002456) rasp (rsp) is located between 063A01 and 063C01 This location is based on the following complementation tests: non-complementing deficiencies: Df(3L)M21 Breakpoints: 062F;063D Df(3L)HR370 Breakpoints: 063A01;063D01 complementing deficiencies: Df(3L)HR232 Breakpoints: 063C01;063D03 Df(3L)HR119 Breakpoints: 063C06;063E Again, in the 'FlyBase format' the location can be specified as follows: Left limit from inclusion within Df(3L)HR370 (FBab0002327) Right limit from non-inclusion within Df(3L)HR232 (FBab0002324) This is all reliable information I can provide at this point. As soon as I verify and double-check position of these genes on the 'molecular map' I will send you an email with all data suitable for FB. With best wishes, Vladic.
