Brief description of the method used for the genetic modification: A) For transfection, a DNA-free system has been used. A nuclease, Cas9, catalyzes double-strand breaks (DSB) in the genome that are repaired by the potato's own repair system, "non homologous end joining". At times, small genetic changes produced by NHEJ repair consisting of 'indels' occur. Cas9 is guided to the gene of interest via an RNA guide B, C, D) For transformation of potato a binary vector system where sequences to be transferred can be found inside the border sequences that form a transfer DNA (T-DNA) was used. The DNA mobilization features are available in a modified Ti plasmid that is not transferred to the plant. For transformation of T-DNA to the potato, Agrobacterium tumefaciens containing the vector has been used. Cut potato leaf tissue was transformed and transgenic shoots were selected on antibiotics. After transformation, the Agrobacterium killed with Cefotaxime. If the recipient or parental plant is a forest tree species, describe ways and extent of dissemination and specific factors affecting dissemination: no Experimental Release Purpose of the release: A, B, C) Potatoes are grown on 1% of agricultural land, but as much as 30% of all fungicides used in Sweden are sprayed on potatoes. Cultivation of resistant potatoes would provide great environmental benefits as the amount of fungicide used could be reduced. D) Due to future global food demand the current crop yields per hectare of land are inadequate and therefore crop productivity needs to be improved. Data suggest that by using plants where the is limitations in the photosynthetic process have been is a viable strategy for increasing crop yield. The purpose is to evaluate agricultural value under field conditions including resistance characteristics. Study the stability of the modified traits, identify any morphological deviations, produce field-grown material for laboratory trials, and produce seed for next year's field trials. The trial is for research purposes only Geographical location of the site: Sweden (Lomma, Kristianstad, Kävlinge, Umeå, Båstad, Öland, Gotland) Size of the site (m2): <10000M2 per site. Maximum 7x10000m2 Relevant data regarding previous releases carried out with the same GM-plant, if any, specifically related to the potential environmental and human health impacts from the release: n/a Environmental Impact and Risk Management Summary of the potential environmental impact from the release of the GMPts: Note especially if the introduced traits could directly or indirectly confer an increased selective advantage in natural environments; also explain any signifant expected environmental benefitsPotato tubers are frost-sensitive and thus depend on temperature to be able to overwinter in the field. Overwintering of tubers can take place in southern Sweden after a mild winter. Seeds can survive regardless of temperature. Very rarely do waste plants of potatoes occur in the cultivated landscape as the seeds and any tubers are destroyed by the next year's tillage, the use of herbicides and competition from the following crop. Potatoes only appear in the cultivation landscape. There have been no reports of wild potato plants. Potatoes also have no compatible relatives in Europe and can therefore only interbreed with other cultivated potatoes. The reported dispersal distance for potato pollen is very short and the suggested distance of 20 m to other cultivated potatoes exceeds the dispersal distance and is therefore considered sufficient to prevent inadvertent crossing. As potato flowers lack nectar, pollen dissemination by honeybees is unlikely and they tend not to forage in potato crops. Flower buds will be removed. Brief description of any measures taken for the management of risks: The experiment will be carried out by the local Rural Economy and Agricultural Society (here abbreviated HS) with the help of members of the Resistance Biology group at VSB, SLU. Both have extensive experience in GM field trials.The experiment will be inspected by HS at least once a week. Responsible scientists will inspect the field during cultivation period. Monitoring of fields after harvest will be carried out by HS according to a mutual written agreement. In order to check for any surviving tubers after harvest, other potato will not be grown in the fields until at least one growing season without surviving potatoes is observed.In order to minimize the spread of pollen to other cultivated potatoes (according to the literature, the distance for the spread of potato pollen is a maximum of ten meters), a protective distance of 20 m will be maintained. All flower buds will be removed. Cleaning of machines, tools and transport vehicles will take place after contact with modified lines. Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release: Not applicable Final report - European Commission administrative Information Consent given by the Member State Competent Authority: Yes
