Jan 6, 2022 · Potato was first domesticated in South America, in the Andes Mountain range between the border of Peru and Bolivia. 5 However, its genomic characteristics and large population of wild species alongside modern cultivars have made the precise determination of its origin difficult. 6 Potatoes were introduced into Spain during the second half of the 16th century, and spread to the rest of Europe ...

Jan 10, 2022 · The availability of potato genome sequence and the development of highly efficient transformation systems make potato a perfect candidate for the application of genome editing technologies to improve important traits leading to a more sustainable potato production (Hameed et al., 2018; Nadakuduti et al., 2018).

Dec 23, 2022 · The application of biotechnological techniques such as genetic engineering and genome editing significantly reduces the time required to introduce or modify a targeted gene, particular allele, or sequence in potato from years to months, and it does so without reshaping allelic combinations (Barrell et al. 2013).

Today, there is much interest in the R-genes found in potato wild relatives and their introduction into commercially successful cultivars by genetic transformation as well as their use in conventional breeding. A good example is the DuRPh project at Wageningen University in the Netherlands which was done from 2006 through to 2015. A detailed accoun...
Among Monsanto’s NewLeaf™ potatoes were NewLeaf™ Plus (available 1997) and NewLeaf™ Y (available 1999) which combined resistance to the Colorado potato beetle (CPB) with Potato leafroll virus (PLRV) and Potato virus Y (PVY), respectively. The former was achieved using the constitutive Figwort Mosaic Virus (FMV) promoter within a construct designed ...
Resistance to the Colorado potato beetle (CPB, Leptinotarsa decemlineata) (Davies 2002; Duncan et al. 2002) and to the potato tuber moth (PTM, Phthorimaea operculella Zeller) (Mohammed et al. 2000; Davidson et al. 2004; Douches and Grafius 2005) have been achieved with genes that encode proteins from the bacterium Bacillus thuringiensis. The follow...
Ali et al. (2017) have provided a review of transgenic strategies for enhancement of nematode resistance in plants. Here I am going to consider two examples. Urwin et al. (2003) were able to demonstrate that constructs based on a cysteine proteinase inhibitor (cystatin) from sunflower and a variant of a rice cystatin conferred similar levels of res...
It is now time to turn to processing quality, starting with the Simplot programme that led to Innate™ potatoes. The programme took 14 years of scientific development, safety assessments, and extensive field tests. It used marker-free transformants and intragenic approaches to silence genes by RNA interference that are key to the expression of black...
In countries with a starch industry there are considerable opportunities to breed or genetically engineer potatoes with novel starches for use in food and non-food products. Some of the functionalities of starch are unique to the polymer as a result of the structure and organization of its linear amylose (17–25% of starch) and highly branched amylo...
Genetic modification can also be used to control glycoalkaloid concentrations. About 95% of the total content is accounted for by α-solanine and α-chaconine, which are differently glycosylated forms (galactose and glucose, respectively) of the aglycone, solanidine. Although not all of the steps in their biosynthesis are known, several intermediates...
On a dry weight (DW) basis, potatoes contain about 10% protein (2% on FW basis), equal to that of most cereals such as rice or wheat, and of good quality for a plant protein. Its biological value of between 90 and 100 is close to whole egg protein which is given a value of 100 (Kanter and Elkin 2019), biological value being the proportion of absorb...
Vitamin A deficiency remains a major health problem in some parts of the world where it is the major cause of blindness in children. Beta-carotene (provitamin A), the precursor of vitamin A, is therefore a target for genetic engineering of carotenoids in potatoes as it is either absent or present only in low concentrations in S. tuberosum and close...

Aug 2, 2019 · Given that the potato gene transformation is efficient and sequence information of diploid RH and double-haploid DM are readily available, potato is a model crop candidate for gene editing experiments (Wang et al. 2015). There are some impediments in genome editing of potato plants brought about by its complex heterozygosity and tetraploid nature.

Mar 19, 2024 · To date, many studies have been conducted on potato genome editing, involving functional analysis of specific genes, the crop breeding toward alterations of desired traits, and improvement in the targeted mutagenesis. Reports on the potato genome editing are summarized in Tables 16.1 and 16.2.
Jan 23, 2023 · The homologous genes of these genes in potato could be found and edited by the CRISPR/Cas system to construct transformants with expected traits. The CRISPR/Cas9 gene editing system, while efficient, is not precise, leaving it vulnerable to knocking out a gene and producing many unwanted results.
