Approved Genetically Modified Potatoes (Solanum tuberosum) for Improved Stress Resistance and Food Safety

Abstract

Potatoes (Solanum tuberosum) are one of the most important crops worldwide. However, its production and nutrient content are endangered by both biotic and abiotic stresses. The main yield losses are caused by pest damage (e.g., Colorado potato beetle and aphids), virus disease (e.g., Potato leafroll virus and Potato viruses Y and X), or oomycete pathogens (like Phytophthora infestans), which also significantly affect the production of antinutrients and toxic metabolites of plants. Therefore, the use of genetic engineering could be an efficient tool, not harmful to the environment, and beneficial to the consumer. In this review, we focus on the main sources of problems in the field of potato production according to approved genetic modifications, their traditional solution and positive impact of gene transfection reducing economic losses, use of insecticides, and improving the nutritional properties of potatoes. We summarize all transgenic events that have been performed on potatoes and have been approved for cultivation and/or direct use or processing as feed or food.

Influence of Edible Potato Production Technologies with the Use of Soil Conditioner on the Nutritional Value of Tubers

“…On the other hand, Zarzecka et al [97] and Baranowska and Mystkowska [98] report that the content of sugars in potato tubers depends on the type of pesticide used. Biotic stresses caused by improper chemical protection intensify the defense response of plants by producing a greater amount of secondary metabolites, the production of which is associated with a change in the sugar balance by plants [99,100].…”

Discovery of Pyrido[1,2-α] Pyrimidinone Mesoionic Compounds as Potential Control Agents Against Potato Virus Y

“…21−23 Although breeding resistant cultivars could prevent PVY infection in plants, this strategy is challenging, time-consuming, and expensive. 24 Pesticide control is simple and efficient; unfortunately, the commonly used virus inactivator such as ningnanmycin has a moderate effect on PVY. 25 Thus, developing an efficient prevention and control strategy for the virus-vector complex is necessary.…”

“…Furthermore, CP binds to receptors of the aphid, leading to effective potato infection through the aphid vector . Aphids have an extremely important epidemiological role for the spread of the PVY virus in a nonpersistant manner with differential transmission efficiency. , Although insecticides are an effective strategy for vector management, they do not significantly inhibit the spread of PVY in the field due to virus-infected tuber transmission or aphids transmitting the virus to healthy plants before dying. − Although breeding resistant cultivars could prevent PVY infection in plants, this strategy is challenging, time-consuming, and expensive . Pesticide control is simple and efficient; unfortunately, the commonly used virus inactivator such as ningnanmycin has a moderate effect on PVY .…”
