jnSi12 [peel-1p::htas-1::mCherry::tbb-2 3'UTR + Cbr-unc-119(+)] II. ezIs2 [fkh-6::GFP + unc-119(+)] III. ltIs37 [pie-1p::mCherry::his-58 + unc-119(+)] IV. GFP expression in spermatheca. mCherry expression in germline nuclei. UX993 sperm have increased mCherry intensity compared to that of its parent strains. [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.]
