This study explores the knockout of the MoDcl1 and MoDcl2 genes in mutant strains, detailing the use of gene-specific probes and flanking sequences for successful identification and validation. We employ a ladder method to characterize the knockout (KO) and ectopic integration of the hygromycin resistance marker (hygR). The analysis includes specific lengths of flanks (2833 bp) for accurate gene targeting and assessments of potential mutations. Results will contribute to understanding gene function and resistance mechanisms in these models.
