From Takeshi Ohama, Kochi University of Technology-Japan, September 2018

This strain is good for overexpression of various transgenes. This is probably due to the relieved transcriptional repression.

It was created by transforming CC-4533 with plasmid pMJ013b and paromomycin resistance was used for the selection of transformants (Zhang et al., 2014), resulting in met-1.

The ble-GFP construct was then introduced to met-1 and UV-mutagenesis was carried out to obtain met1(UVM)-47A. This strain is resistant to paromomycin and Zeocin.

The drc11 CLiP mutant LMJ.RY0402.068819 was co-transformed with pHyg and a wild-type, cDNA clone of  DRC11 containing a SNAP tag at its carboxy-terminus, selected on hygromycin, and screened for the presence of the SNAP tag by Western blot. The drc11 (fap82) mutation on chromosome 7 rescued in this strain.

SAGA1 was cloned into the pRAM118 vectors and transformed into strain saga1 (CC-5420). Lines were then selected for antibiotic resistance positive fluorescence. Further details are available in the below publication.

To minimize silencing it is recommended to propagate on paromycin and hygromycin.
