Genome-editing has tremendous potential for crop improvement, and although implemented in many crops, it has yet to be fully realized in clonally propagated polyploids like potato. Nevertheless, genome-editing using TALENs and CRISPR/Cas9 has been successfully demonstrated in a number of clonally propagated crops presented in Table 1. Plant Cell 23, 4507–4525. doi: 10.1046/j.1365-313X.1997.11020227.x, Mweetwa, A. M., Hunter, D., Poe, R., Harich, K. C., Ginzberg, I., Veilleux, R. E., et al. A., and Charpentier, E. (2012). 60, 520–523. Using RNPs, possibility of integration of plasmid-derived DNA sequences or foreign DNA into the host genome can be eliminated. The Cas9 protein continues to be expressed in the cell for several days when delivered as a plasmid, whereas it is degraded within 24 h when delivered as RNPs, improving the specificity of the reagent (Zetsche et al., 2015). Such qualitative differences in SGAs in terms of organ specificity and composition provide opportunities to select specific targets for potato improvement via genome engineering. Mol. J.

Targeted base editing in rice and tomato using a CRISPR-Cas9 cytidine deaminase fusion. The CRISPR/Cas9 system has demonstrated great potential in various crop species due to simplicity of use and versatility of the reagents (Jiang W. et al., 2013; Sun et al., 2015; Svitashev et al., 2016; Zhang et al., 2016; Shimatani et al., 2017; Soyk et al., 2017). By transient expression of reagents as plasmid DNA or via RNPs in potato protoplasts, mutagenized lines in all four alleles were regenerated with tubers that had the desired high amylopectin starch (Andersson et al., 2017, 2018). doi: 10.1080/07352689709701946, Fry, W. (2008). For multiplexing, to target more than one gene at a time, Cas12a requires only a single RNA PolIII promoter to drive several crRNAs, whereas Cas9 requires relatively large constructs (Zetsche et al., 2017). A CRISPR-Cpf1 system for efficient genome editing and transcriptional repression in plants.

Crit. Efficient DNA-free genome editing of bread wheat using CRISPR/Cas9 ribonucleoprotein complexes. Biotechnol. However, transient expression in protoplasts, for example, can achieve gene edits, and regeneration of the edited protoplasts can create edited plants without any foreign DNA and hence are exempt from regulation by USDA/APHIS (Clasen et al., 2016) (“Am I Regulated?”2). 54, 9882–9887. doi: 10.1016/j.molp.2016.11.013, Ma, J., Xiang, H., Donnelly, D.

Improving potato storage and processing characteristics through all-native DNA transformation. Since Science named it as “Breakthrough of the Year” and Fortune magazine hailed it as “Biotech’s Billion Dollar Breakthrough” in 2003, RNAi has significantly gained prominence as the method of choice for researchers sleuthing the structure and function of important genes. Protoplasts have greater transformation efficiency compared to other methods (Jiang F. et al., 2013; Dlugosz et al., 2016; Baltes et al., 2017). doi: 10.1111/j.1469-8137.2010.03210.x, Moehs, C.

L. (2013). J. Vis. The first successful demonstration of the use of TALENs in a tetraploid potato cultivar was by knocking out all four alleles of Sterol side chain reductase 2 (StSSR2) (Sawai et al., 2014) involved in anti-nutritional sterol glycoalkaloid (SGA) synthesis (Itkin et al., 2011, 2013). J. Genome editing case studies in clonally propagated crops. A Genomics Solution for Increased Food Demand Crops are an essential food resource: wheat, rice, and maize supply >60% of … Canonical disease resistance genes, R-genes, belong to nucleotide-binding, leucine-rich repeat (NLR) class of intracellular immune receptor proteins that recognize pathogen effectors to initiate defense responses in the plant (El Kasmi and Nishimura, 2016; Jones et al., 2016). Genome-editin… Potato is chosen for case studies, since it has been subjected to more genome-editing, even though it is a tetraploid, compared to other crops. Genome-editing was successfully applied in diploid potato to overcome gametophytic SI by knocking-out the Stylar ribonuclease gene (S-RNase) (Ye et al., 2018).
