Abstract

Cultivated potato, Solanum tuberosum Group Tuberosum L. (2n = 4x = 48) is a heterozygous tetraploid crop that is clonally propagated, thereby resulting in identical genotypes. Due to the lack of sexual reproduction and its concomitant segregation of alleles, genetic engineering is an efficient way of introducing crop improvement traits in potato. In recent years, genome-editing via the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 system for targeted genome modifications has emerged as the most powerful method due to the ease in designing and construction of gene-specific single guide RNA (sgRNA) vectors. These sgRNA vectors are easily reprogrammable to direct Streptococcus pyogenes Cas9 (SpCas9) to generate double stranded breaks (DSBs) in the target genomes that are then repaired by the cell via the error-prone non-homologous end-joining (NHEJ) pathway or by precise homologous recombination (HR) pathway. CRISPR/Cas9 technology has been successfully implemented in potato for targeted mutagenesis to generate knockout mutations (by means of NHEJ) as well as gene targeting to edit an endogenous gene (by HR). In this chapter, we describe procedures for designing sgRNAs, protocols to clone sgRNAs for CRISPR/Cas9 constructs to generate knockouts, design of donor repair templates and use geminivirus replicons (GVRs) to facilitate gene-editing by HR in potato. We also describe tissue culture procedures in potato for Agrobacterium-mediated transformation to generate gene-edited events along with their molecular characterization.
