Abstract:
... CRISPR/Cas9 technology is rapidly spreading as genome editing system in crop breeding. The efficacy of CRISPR/Cas9 in tomato was tested on Psy1 and CrtR-b2, two key genes of carotenoid biosynthesis. Carotenoids are plant secondary metabolites that must be present in the diet of higher animals because they exert irreplaceable functions in important physiological processes. Psy1 and CrtR-b2 were cho ...

Abstract:
... Increased tolerance to pathogens is an important goal in conventional and biotechnology-assisted grapevine breeding programs worldwide. Fungal and viral pathogens cause direct losses in berry production, but also affect the quality of the final products. Precision breeding strategies allow the introduction of resistance characters in elite cultivars, although the factors determining the plant’s ov ...

Abstract:
... Genetically modified (GM) crops undergo large scale multi-location field trials to characterize agronomics, composition, and the concentration of newly expressed protein(s) [herein referred to as transgenic protein(s)]. The concentration of transgenic proteins in different plant tissues and across the developmental stages of the plant is considered in the safety assessment of GM crops. Reference o ...

Abstract:
... Plants have co-evolved with a diverse array of pathogens and insect herbivores and so have evolved an extensive repertoire of constitutive and induced defence mechanisms activated through complex signalling pathways. OXI1 kinase is required for activation of mitogen-activated protein kinases (MAPKs) and is an essential part of the signal transduction pathway linking oxidative burst signals to dive ...

Abstract:
... Human copper/zinc superoxide dismutase (CuZn-SOD) and extracellular superoxide dismutase (EC-SOD) are two superoxide dismutases that scavenge reactive oxygen species (ROS). Their biological role of eliminating oxidative stress caused by excessive ROS levels in living organisms has been utilized in medical treatment, preventing skin photoaging and food preservation. In this study, we employed two s ...

Subject:
cultivars; databases; field experimentation; glycoalkaloids; phenotype; potatoes; protocols; risk assessment; transgenic plants; Netherlands; Sweden
Abstract:
... Most regulations worldwide stipulate that a new genetically modified (GM) crop event has to be compared to its closest non-GM counterpart as a corner stone of the pre-market risk assessment. To this end the GM crop and its comparator should be grown in field trials for a phenotypic comparison as well as for subsequent detailed analysis of the composition of the two crop varieties. A more in-depth ...

Abstract:
... The scientific journal Nature Methods have just retracted a publication that reported numerous unexpected mutations after a CRISPR-Cas9 experiment based on collecting whole genome sequencing information from one control and two experimental genome edited mice. In the intervening 10 months since publication the data presented have been strongly contested and criticized by the scientific and biotech ...
