Using RNPs, possibility of integration of plasmid-derived DNA sequences or foreign DNA into the host genome can be eliminated. (2006). (A) Double stranded DNA (dsDNA) break repair in a cell occurs either by non-homologous end joining (NHEJ), where the cleaved DNA molecule is simply rejoined, often with indels in coding regions (green) that result in gene knock-out or by homologous recombination (HR), where a donor repair template (red) can be used for targeted knock-in experiments, where a single or few nucleotides alterations, insertion of an entire transgene or suites of transgenes can be made. Biosynthesis of antinutritional alkaloids in solanaceous crops is mediated by clustered genes. Potato is a global food security crop and is the third most important food crop after rice and wheat (Devaux et al., 2014). Only certain cultivars of potato are amenable to transformation and others need to be tested for transformation and regeneration in tissue culture. Effects of storage temperature on the contents of sugars and free amino acids in tubers from different potato cultivars and acrylamide in chips.

Due to continued high rates of evolution of effector proteins, pathogens overcome recognition, thereby limiting the durability of resistance (Raffaele et al., 2010; Dong et al., 2014). Base editing has been successfully applied in plants to confer both gain of function by incorporating correct mutations and loss of function by generating knock-out mutations (Chen et al., 2017; Li et al., 2017; Lu and Zhu, 2017; Shimatani et al., 2017; Zong et al., 2017; Kang et al., 2018). doi: 10.1146/annurev-arplant-042811-105552, Waltz, E.
