Subject: errors in cytology Flybase project members: It has come to my attention that there are some errors in the cytology of some of the deletions that I recovered in the 63 region. The following are shown as the correct cytology Df(3L)HR370 63A1-D1 Df(3L)HR232 63C1-D3 Df(3L)HR277 63C1-64B12 Df(3L)HR298 63B6-64A6. The cytology listed in the 1992 Redbook (under l(3)63)is correct. Mea Culpa, Arthur Wohlwill Subject: Re: errors in cytology Hi Arthur, Given that there has been some confusion about the correct cytology for the Df(3L)HR chromosomes in your message to FlyBase, please could you indicate which of the alternatives are correct for each Df. Lindsley and Zimm, | Wohlwill and Bonner 1992, page 382 | Genetics 128: 763--775 \---------------------|------------------------ Df(3L)HR370 63A1;63D1 | 63A1;63D10 Df(3L)HR232 63C1;63D3 | 63C1;63D1 Df(3L)HR277 63B12-C1;64B12 | 63B6;64B12 Df(3L)HR298 63B6;64A6 | 63B1;64A6 Many thanks! Rachel \-------------------------------------------------------------- Rachel Drysdale. FlyBase (Cambridge), \-------------------------------------------------------------- Subject: errors in cytology Dr. Drysdale: All of the enteries in Lindsley and Zimm are correct whereas the Genetics paper contains some errors. of the Sorry for the confusion. Subject: cytology errors Dr. Ashburner: I am sorry that I did not make myself clear. All of the entries in Lindsley and Zimm are correct---mistakes were made during preparation of the paper. Your information on HR370 is correct (it is 63A1-63D1 The Genetics paper says the right breakpoint is D10. Other corrections HR232---should be 63C1-D3 not 63C1-63D1 HR277---should be 63C1-64B12 not 63B6-64B12 HR298---should be 63B6-64A6 not 63B1-64A6 Finally pdp7 duplicates vn (according to Garcia-Bellido etal 1994 PNAS 91 10222-10226) whereas your entry, citing the same reference, says that it deletes or disrupts vn. Rachel Drysdale also contacted me about these errors---I sent her a similar message. Again, I am sorry for the errors, Arthur Wohlwill
