Fig. 3From: Targeting the autosomal Ceratitis capitata transformer gene using Cas9 or dCas9 to masculinize XX individuals without inducing mutationsRT-PCR analysis of reverted XX males. (A) The six XX males from injection set n. 2 (Table 1) showed only male-specific Cctra transcripts (500 bp) and shorter less abundant splicing variants. No traces of female-specific transcripts were visible in the gel electrophoresis (160 bp) (B) RT-PCR with MoY-specific primers indirectly confirmed the absence of the Y chromosome in these six fully reverted XX males and its presence in XY flies (positive control)Back to article page
