Strain Genotype Species Description
MLC1016 nDf50 nDf49 II; lucIs20. C. elegans lucIs20 [mir-35p::mirtron-35 + myo-2::mCherry]. Position of integrated transgene unknown (not on X). mir-35 family mutant expressing a mirtron-version of mir-35. nDf50 nDf49 mutants are partially rescued by expression of mirtron-35 from integrated transgene; mild mir-35-related phenotypes are more severe at elevated temperatures. Strain is derived from injection into parental strain MT14533. Position of integrated transgene unknown (not on X). Reference: Dexheimer, PJ, et al. Curr Biol. 2020. in press.

MLC903 nDf67 mir-52(n4100) IV/nT1 [qIs51] (IV;V); nDf58 X, lucIs24. C. elegans lucIs24 [mir-52p::mirtron-51 + elt-2::dsRed + myo-2::mCherry]. Pick GFP+ animals to maintain balanced line. Balanced mir-51 family mutant expressing a mirtron-version of mir-51. Heterozygotes are wild-type with pharyngeal GFP signal, and segregate wild-type GFP, arrested nT1[qIs51] aneuploids, and non-GFP mir-51 family homozygous mutants. Pick wild-type GFP+ and check for correct segregation of progeny to maintain. Non-GFP mir-51 family homozygous mutants rescued by mirtron-51 transgene are viable, but slow-growing and sick. Strain is derived from injection into parental strain MT17143. lucIs24 is a spontaneous integrant originating from a complex extra-chromosomal array, the genomic location of the transgene is unknown.
