Endogenous drsh-1 tagged at both N- and C-termini with the auxin-inducible-degron (AID) peptide. Endogenous pash-1 tagged with the AID peptide at the C-terminus. Strain expresses modified Arabidopsis thaliana TIR1 tagged with mRuby in soma and germline. In addition, strain expresses mirtron-versions of mir-35 and mir-51, which are processed independently of Drosha and Pasha. miRNA biogenesis can be stringently inhibited via simultaneous removal of Drosha and Pasha, causing absence of all canonical miRNAs and embryonic lethality upon Auxin treatment.

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.

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.
