Candida tropicalis, a diploid asporogenic yeast, is frequently utilized in industrial applications and research studies. However, the low efficiency of genetic transformation limits the strain improvement by metabolic engineering. A reliable transformation and efficient deletion of target gene are prerequisite for molecular improvement of C. tropicalis. In this study, an efficient approach for genetic transformation of C. tropicalis was developed based on the URA3 gene as a reusable selection marker and bot...
