Easing the regulatory process around certain genetic engineering techniques

January 22nd, 2018 / Alliance for Science, US

The European Union and Australia took steps this week toward easing the regulatory process around certain genetic engineering techniques.
In the EU, a legal opinion found that mutagenesis techniques are, in principle, exempt from the rules that govern genetically modified organisms (GMOs), though individual EU states can regulate their use. Meanwhile, …

Scientists use CRISPR-Cas9 technology to improve drought and salt tolerance in rice

January 11th, 2018 / ISAAA, US

The ∆ 1 -pyrroline-5-carboxylate synthetase (P5CS) is the rate-limiting enzyme in proline (Pro) synthesis and is involved in drought and salt stress tolerance in plants. An OsP5CS gene was isolated from a stress-treated commercial rice variety, BC15.
The length of rice OsP5CS was 2173 nucleotides, containing an ORF encoding for …

Gene editing: The key to food security in a warmer world?

January 8th, 2018 / Deutsche Welle, Germany

At the Justus Liebig University in Gießen, Germany, scientist Karl-Heinz Kogler is fighting diseases that affect wheat and other crops. His new weapon is the gene-editing technique CRISPR-cas9. It allows him to literally edit organisms, removing bits of DNA responsible for undesirable outcomes.
Recently, he and his team edited the wheat …

How gene editing will boost crop yields

December 19th, 2017 / Successful Farming, US

On the surface, a light switch and gene editing have as much in common as a linebacker does with a ballerina.
Dig a bit deeper, though. “In a very simple way, the main application of gene editing is like flipping a light switch on and off,” says Federico Tripodi, …

Use of CRISPR systems in plant genome editing: toward new opportunities in agriculture

November 30th, 2017 / Emerging Topics in Life Sciences, UK

Initially discovered in bacteria and archaea, CRISPR–Cas9 is an adaptive immune system found in prokaryotes. In 2012, scientists found a way to use it as a genome editing tool. In 2013, its application in plants was successfully achieved. This breakthrough has opened up many new opportunities for researchers, including the …

The regulatory status of gene-edited agricultural products in the EU and beyond

September 25th, 2017 / Emerging Topics in Life Sciences

Governments all over the world are struggling with the regulatory status of gene-edited organisms. Are they regulated? Should they be regulated? In the present paper, the main focus is on the regulatory status of gene-edited organisms within the European regulatory framework. A stepwise analysis is performed that comes to the …

Can CRISPR feed the world?

May 22nd, 2017 / Phys.org

As the world’s population rises, scientists want to edit the genes of potatoes and wheat to help them fight plant diseases that cause famine.
By 2040, there will be 9 billion people in the world. “That’s like adding another China onto today’s global population,” said Professor Sophien Kamoun of the Sainsbury …

Editing out pesticides

August 12th, 2016 / Nova Next, US

This summer, more than a million tonnes of chardonnay grapes are plumping on manicured vineyards around the world. The grapes make one of the most popular white wines, but their juicy fruit and luscious leaves are also targets for diseases such as downy mildew, a stubborn fungus-like parasite. If left …

Gene-edited crops ‘should not be subject to government oversight’

February 9th, 2016 / Nature Genetics

An editorial in Nature Genetics has called for gene-edited crops to be subject to no more regulation than crops developed through conventional breeding. In an accompanying commentary, Chinese, German and US researchers make the case that many applications of gene-editing would lead to crops that would, at least in theory, …

How bacteria invented gene editing

February 8th, 2016 / BBC.com, UK

Gene editing is much more common in nature than you might think. It actually has ancient ro Read …
