CRISPR-Cas9 Technology for Genotyping Plant Genomes

This technical report details the application of CRISPR-Cas9 technology for the depletion of repetitive DNA in the high-throughput genotyping of lentil (Lens culinaris) genomes. The report outlines the challenges associated with traditional genotyping methods, particularly in species with large genomes that contain a high proportion of repetitive DNA. It describes the design of a custom set of guide RNAs (gRNAs) aimed at targeting and depleting repetitive elements, thereby enhancing the sequencing focus on single-copy regions. The results indicate a significant increase in the number of genotyped bases and genetic variants identified, demonstrating the effectiveness of the CRISPR-Cas9-driven approach in improving genotyping accuracy. Furthermore, the report discusses the implications of this method for large-scale genomic analysis in lentils and other plant species with similar genomic structures. The findings contribute to the ongoing efforts in population genomics and genome-wide association studies, emphasizing the need for cost-effective and efficient genotyping methods.
