May 26, 2020 · IARC (International Agency for Research on Cancer): Glyphosate cancer determination challenged by world consensus. To help demonstrate the power of biotechnology, consider the following analogy ...
Potato ( Solanum tuberosum L.) is the third most important crop worldwide and a staple food for many people worldwide. Genetically, it poses many challenges for traditional breeding due to its autotetraploid nature and its tendency toward inbreeding depression. Breeding programs have focused on productivity, nutritional quality, and disease ...

Late blight caused the Irish Potato famine of the 19th Century. It results from infection by the fungal-like mould Phytophthora infestans, causing losses of $6B/ year for potato and tomato production.Potato is the fourth most important crop in the world and widely grown in Europe, USA, South America, Canada, China, India and Africa.Potato is easy to modify using strains of nature’s genetic engineer the bacterium Agrobacterium tumefaciens which transfers specific genes into cells of potato. Pieces of potato stem are used for making the genetically modified potato plants. Cells which have received the gene from the bacterium form a mass of undifferentiated cells, or callus, on ...
Traditional breeding techniques have failed to produce varieties that have durable resistance to late blight. This is because they have tended to introduce resistance genes one at a time which are easily overcome by the pathogen. Professor Jonathan Jones says: “If you put in three effective genes at once they are all in effect saving each other bec...
Bruising causes millions of potatoes to be thrown away every year. Maris Piper lines used in these trials have a gene switched off, or silenced, which makes the tuber less prone to bruising and ensure that the potato meets customer quality specifications. “There is a lot of wastage from bruising. Potato harvest is in September/October so to ensure ...
Sep 14, 2022 · BASF Plant Science developed two approved GM potatoes (Amflora and Starch Potato), but none of them are approved for cultivation and are no longer marketed. The inserted gene minimizes the amylose content by lowering the level of granule-bound starch synthase.
These findings suggested that procedures used in gene technology could make plants harmful. Based on this, Dr Pusztai claimed GM foods could have dangers that were not adequately revealed by testing. Genetically modified potatoes of the type used by Dr Pusztai are not being produced for human consumption.

from Farm to Plate. GMOs allow farmers to grow more with less resources.3. In a single year, GMOs allowed farmers to use 59.7M fewer acres of land to grow the same amount of food.4. GM potatoes reduce pesticides with late blight disease protection that enables farmers to reduce fungicides by 50%.5. GMOs go through rigorous review.
Dec 5, 2019 · The field trials follow successful lab experiments to modify Maris Piper potatoes with late blight resistance genes from wild relatives of potato called Solanum americanum and Solanum venturii.
