<b>Expression of the eGFP::I-PpoI fusion protein in <i>Anopheles gambiae</i> testes.</b>

Pictured is a confocal image of a mosquito testicle stained for DNA (with DAPI, shown in red) overlaid with the expression pattern of the eGFP-tagged I-PpoI endonuclease protein (shown in green). The testis hub region (lower right part of the picture) does not stain for eGFP, suggesting that stem cells are not affected by the potentially toxic endonuclease. Expression of the protein during later stages of spermatogenesis induced dominant male sterility and sex chromosome transmission ratio distortion, without disrupting the production of functional sperm (see Windbichler et al., doi:10.1371/journal.pgen.1000291).
