Generation of homozygous, C.a. LPT1 deletion strains OMY15, OMY20. C. albicans strain SN152 (29) was transformed with a PCR-generated construct containing C.a. LEU2 flanked by ~60 nucleotides of C.a. LPT1 sequence (A). Transformants were selected on SC–Leu media and genotyped by PCR using oligo pairs lp1, lp2 or lp1, le2 (B). Subsequently, LPT1/lpt1Δ::LEU2 strains were transformed with a similar PCR-generated construct containing C.a. HIS1 with PCR genotyping using a lp1, hi2 oligo pair.
