From rd120@XXXX Tue Mar 10 11:46:29 1998 To: mfrolov@XXXX Subject: ADRC: 406A Dear Elizaveta, I am writing in connection with your abstract for the upcoming Washington DC ADRC: 'Identification of a novel modifier of white gene expression.' You describe a new gene identified as a dosage sensitive P-element insertion modifier of w allele expression. Do you have a gene symbol/name or cytological location for the new gene? Does it correspond to one of the genome project insertions? It is nice if we can keep as many gene records as possible anchored to the map. Thank you for your help, with best wishes, Rachel.

We named this gene Pow (Passion-of-white), since the gene is a dosage sensitive regulator of white gene expression. On the P1 phage map, l(2)10642 sequences belong to DS06061.2 clone. If you need any other information please don't hesitate to contact me. Sincerely yours, Elizaveta.
