Jan 6, 2022 · 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 ...

As Danforth Center President Roger Beachy, the first to develop a virus-resistant tomato, describes it, the first-generation GM crops were intended to help farmers reduce not only the impact of pests, but also the use of agrochemicals in modern crop production---a legacy of the Green Revolution. After a decade of cultivation, environmental benefits...
After seven years of GM crop production and no apparent health effects, potential environmental risks—particularly gene flow into other species—have eclipsed food safety as a primary concern. As pollen and seeds move in the environment, they can transmit genetic traits to nearby crops or wild relatives. Many self-pollinating crops, such as wheat, b...
“The gene flow risk that keeps me awake at night is the possibility of hybridization between crops engineered to manufacture poisons and related crops intended for human consumption,’’ says plant geneticist Norman Ellstrand. Indeed, this application of GM crops seeks to turn corn into cost-effective pharmaceutical factories and may bear the mark...
Current regulatory constraints have a choke-hold on innovations for genetic modifications that seek to improve subsistence crops, such as rice. Golden rice, yellowed in appearance because it is infused with the vitamin A precursor beta-carotene, could save thousands of malnourished people each year from blindness and the other vitamin A–deficie...
One way to minimize the problems associated with gene flow is to introduce sterility, such that pollen cannot transmit information. Richard Jefferson has high hopes for an accessible, cheap way for farmers to produce genetically superior seeds, called apomixis. But similar concepts have been floated before. The controversial terminator technol...
“Agricultural biotechnology is here to stay’’ read a recent opinion piece by Gianessi. No doubt he is correct. As genetic engineering continues to evolve, transgenic methods will become just one of many tools. In fact, some researchers are currently focusing their work on manipulating an organism’s own genetic code to achieve desired traits. Scient...

Jan 10, 2022 · Importance of Biotechnology Application in Potato. Potato (Solanum tuberosum L.) is a worldwide important crop plant that produces high nutritional quality tubers.It is the fourth most important staple crop (after wheat, corn, and rice) in terms of production and demand, with around 378 million tons produced annually (Campos and Ortiz, 2020).

Apr 9, 2021 · Abstract. Gene editing and genetic transformation are alternatives to sexual hybridization for potato improvement. Engineered nucleases catalyse a double-stranded DNA break at a specific location in the genome so that desired DNA modifications can occur at the break site rather than at random.
