Genetically engineered modification of potato to form amylopectin-type starch
TL;DR: In this paper, genetically engineered modification of potato for suppressing the formation of amylose-type starch is described and three fragments for insertion in the antisense direction into the potato genome are also described.
Journal ArticleDOI
Efficient targeted multiallelic mutagenesis in tetraploid potato (Solanum tuberosum) by transient CRISPR-Cas9 expression in protoplasts.

TL;DR: Altered starch quality with full knockout of GBSS gene function in potato was achieved using CRISPR-Cas9 technology, through transient transfection and regeneration from isolated protoplasts, verifying similar results found in other plants that high homology between guide sequence and target region near the protospacer adjacent motif (PAM) site is essential.
Journal ArticleDOI
Genome editing in potato via CRISPR-Cas9 ribonucleoprotein delivery
Mariette Andersson,Helle Turesson,Niklas Olsson,Ann Sofie Fält,Pia Ohlsson,Matías Nicolás González,Matías Nicolás González,Mathias Samuelsson,Per Hofvander +8 more
TL;DR: This work has implemented a DNA-free genome editing method, using delivery of CRISPR-Cas9 ribonucleoproteins (RNPs) to potato protoplasts, by targeting the gene encoding a granule bound starch synthase (GBSS, EC 2.4.1.242).
Journal ArticleDOI
Replacing fossil oil with fresh oil – with what and for what?
TL;DR: The research reviewed in this paper aims to develop metabolic engineering technologies to radically increase the yield and alter the fatty acid composition of plant oils and enable the development of new and more productive oil crops that can serve as renewable sources of industrial feedstocks currently provided by non-renewable and polluting fossil-based resources.
Journal ArticleDOI
Reduced Enzymatic Browning in Potato Tubers by Specific Editing of a Polyphenol Oxidase Gene via Ribonucleoprotein Complexes Delivery of the CRISPR/Cas9 System

TL;DR: It is demonstrated that the CRISPR/Cas9 system can be applied to develop potato varieties with reduced enzymatic browning in tubers, by the specific editing of a single member of the StPPO gene family.
