Fig. 4

a Diagram of individual Stellate (Ste) and Su(Ste) repeat units. Su(Ste) repeats contain promoters at each end, allowing for bidirectional expression of complementary transcripts. Su(Ste) transcripts produced from the sense promoter are labeled as Su(Ste), and transcripts produced by the 1360TE/Hoppel TE are labeled as Su(Ste)-AS. b Widespread Su(Ste) antisense (Su(Ste)-AS, CR42418) transcript expression in testis. c Higher magnification of Su(Ste)-AS (CR41533) expression in gonialblast and spermatogonia nuclear foci and early spermatocyte cytoplasm. d Su(Ste) (CR42430) sense expression in spermatogonia nuclei and spermatocyte cytoplasm. eg Expression patterns at the apical tip of the testis detected by HCR FISH using oligonucleotide probes that specifically target e Su(Ste)-AS (red), f Su(Ste) (blue) or g Ste (yellow). hj Pairwise combinations of Su(Ste)-AS, Su(Ste) and Ste. km Higher magnifications of regions boxed in (hj). Arrows indicate main nascent sites of expression. Blue arrowheads indicate minor sites of Su(Ste) localization that overlap with major sites of Ste localization. Scale bars = 20 μm.
