Depositor Comments

The construction of the episomal plasmid enabling the expression of Ercas12a together with the crRNA was performed by Gibson assembly of five fragments flanked with compatible SHR sequences (Kuijpers et al., 2013). The yeast marker cassette A-pAgTEF1-hphNT1R-tAgTEF1-B was amplified from plasmid pMEL12 (Mans et al., 2015) . The yeast origin F-panARSopt-C was amplified from pUD530 (Gorter de Vries et al., 2017) . The E. coli origin and marker, I-ori blaR-A, was amplified from pUD532 (Gorter de Vries et al., 2017) . The crRNA insertion expression cassette (short DR and RNApolII design) was amplified from pUD1190 . The Ercas12a expression cassette was amplified from pUDE1093 . Gibson assembly of these five fragments resulted in pUDP293.
