E. coliDH5α strain was transformed with plasmids carrying appropriate inserts to clone and generatedeletion strains of C. glabrataORFs(Sambrook, 2001). Ultracompetentcells stored at -70⁰C were thawed on icefor 5-10 min. 5 μlligated plasmid was added to100 μlultracompetent cells andcells were incubatedon ice. After 30 min, competent cells were subjected to heat shock at 42⁰C for 90 seconds. Cells were immediately transferredtoicefor 2-3min. Next, 800 μlSOC (or LB) medium was added and cells were allowed to recover for 45 minon a shaker incubator set at 37⁰C.After the recovery, cells were centrifuged at 2,500g for 4 min. Medium supernatant was discarded and cells were resuspended in 200 μlfresh sterile LBmedium. Cells were plated on LB agar medium containing appropriate antibiotics. Plates wereincubatedat37⁰C for 12-16 h
