ieSi1 [htp-3p::GFP::him-8 + unc-119(+)] II. ltIs37 [pie-1p::mCherry::his-58 + unc-119(+)] IV. ieSi1 is prone to silencing; GFP might not be visible at lower magnifications. [NOTE: the ltIs37 [pie-1p::mCherry::his-58 + unc-119(+)] IV transgene was previously annotated as itIs37 in this strain. The correct name of the transgene is ltIs37 and not itIs37.] Reference: Wynne DJ, et al. J Cell Biol. 2012 Jan 9;196(1):47-64.

ieSi11 [syp-3p::EmeraldGFP::syp-3::syp-3 3'UTR + Cbr-unc-119(+)] II. ieSi11 was inserted into ttTi5605 II using MosSCI. Expression of GFP::SYP-3 largely complements syp-3(ok758), but some meiotic nondisjunction is detected above the N2 background (85% embryonic viability; ~1% male self-progeny;). GFP::SYP-3 expression is readily detected in spermatocytes and oocytes in the germline, and localizes to the interface between paired homologous chromosomes during most of meiotic prophase.
