y promoter sequences have been replaced with heterologous Hsp70 promoter sequences by targeted gene replacement at yh12w+. yhsp70-tata is identical to yhsp70, except that in addition, the 6bp TATA box in the eve promoter has been replaced with CCCGGG.
Body colour: pigmentation score (where 1 = null/nearly null, 5 = wild type/nearly wild type): homozygote: 5 (wing), 5 (body), hemizygote: 4+-5 (wing), 4+-5 (body), yhsp70-tata/y1 : 4-5 (wing), 4+-5 (body), yhsp70-tata/y2 : 5 (wing), 5 (body), yhsp70-tata/y82f29 : 4-5 (wing), 4+-5 (body).
