abstract：:The cytoplasmic virus-like element pWR1A from Debaryomyces robertsiae encodes a toxin (DrT) with similarities to the Pichia acaciae killer toxin PaT, which acts by importing a toxin subunit (PaOrf2) with tRNA anticodon nuclease activity into target cells. As for PaT, loss of the tRNA methyltransferase Trm9 or overexpr...
