CRISPR is cheap and easy enough to be employed in every lab not just by major ag-biotech companies. A serious roadblock standing in the way of researchers, however, threatened to limit the technology potential for plant breeding: intellectual property (IP) rights. The good news is that two major patent holders, DuPont Pioneer and the Broad Institute of MIT and Harvard, have agreed to create a joint licensing framework for genome editing in agriculture. As a result, academic researchers are allowed to use CRISPR on plants free of charge, while biotech companies interested in commercial ag applications have a simplified procedure to access to the tools they need.Continue reading →
Wheat contains many genes coding for proteins that are toxic to people with celiac disease (gliadins), but CRISPR could edit them all out. Researchers at the Institute for Sustainable Agriculture (Córdoba, Spain) have managed to knockout up to 35 of these genes, reducing immunoreactivity by up to 85%. The 100% goal now seems to be at hand. But is biotech “gluten-free” bread tasty? And is it going to reach the market? We asked plant scientist Francisco Barro, corresponding author of the paper recently published in Plant Biotechnology Journal. Continue reading →
The European Commission is organising the high-level conference “Modern Biotechnologies in Agriculture – Paving the way for responsible innovation”. This one-day event takes place in the Charlemagne Building today, from 9.30 to 18.00. The aim is to stimulate an informed and open debate among all stakeholders on how the EU can benefit from modern biotechnologies and innovation in the food and agricultural sector while maintaining high safety standards. The participants are prominent European policy makers, relevant industry stakeholders, representatives of civil society, scientists, and government experts. Webstreaming is available. For further information, see the conference website.
Spring in Japan is pink as cherry blossoms, but summer turns violet as the flowers of a climbing plant frequently grown in the gardens of the Rising Sun. It is a kind of morning glory, of the Ipomoea nil species, locally known as Asagao. This plant had its genome sequenced in 2016 and is now inaugurating the CRISPR era in floriculture.

CRISPR is set to make its commercial debut in maize fields in 2020. The honor (and burden) of probing the market, as the first product developed with the revolutionary technique for genome editing, is up to a kind of corn called waxy for the appearance of its kernels. Its starch is almost entirely amylopectin and almost zero amylose. Conventional waxy varieties already available to farmers have some yield drag due to the undesirable genetic baggage introduced by breeding. Conversely, DuPont Pioneer researchers created a waxy version of their best corn without yield drag or foreign DNA by editing out a gene for an enzyme that produces amylose. Amylopectin is used for the production of goods such as paper adhesives and food thickeners. What remains after its extraction is a protein flour that can be employed as feed. It may sound like a low-profile debut for the celebrated genome editing technology that is asked to succeed where GMOs have failed: gaining consumer confidence. But this is a deliberate strategy, as explained below by Neal Gutterson, DuPont Pioneer’s vice president of R&D.Continue reading →
These are exciting times for wheat geneticists. Wheat has a huge hidden potential and new technologies are releasing the bottleneck in breeding. We asked Cristobal Uauy, project leader at the John Innes Centre in Norwich (UK), how genome editing is going to impact the field. Continue reading →
