Flowering with CRISPR

Multiplexed heritable gene editing using RNA viruses and mobile single guide RNAs

FT (Flowering Locus T) is a small protein that helps plants know when to flower. Now it also allows geneticists to create heritable gene edits in the shoot apical meristem. The trick is a guide RNA augmented with an FT sequence that promotes cell-to-cell mobility. The result is a new approach to gain access to the germline.

CRISPR crops in the news

Credit Pairwise Plants

European scientists must wait for the EC to carry out targeted consultations with Member States and EU-level stakeholders. Then the Commission study on new genomic techniques will be delivered by 30 April 2021. In the meantime, the United States has decided to relax the rules for biotech crops.

Prime-edited rice & CRISPR golden rice

Do you remember prime editing? It’s the new ‘search-and-replace’ genome editing technology that mediates targeted insertions, deletions, all 12 possible base-to-base conversions, and combinations thereof. The first good news is that David Liu et al. adapted prime editors for use in rice and wheat, so don’t miss their paper in Nature Biotechnology.

A vertical farm for CRISPR food

Do you want it locally grown, water-saving and pesticide-free? Urban agriculture might suit you, with a little help from gene editing. Zachary Lippman’s team has already succeeded with Solanaceae fruit crops, optimizing tomatoes and ground-cherries for indoor production (see their paper in Nature Biotechnology).

An activist’s view on agbiotech & sustainability

danielle-nierenberg-4

Danielle Nierenberg is President of Food Tank and an influential voice on food issues. She interviewed hundreds and hundreds of farmers, researchers, government leaders, NGOs and journalists in 50 plus countries in sub-Saharan Africa, Asia, and Latin America over the last several years. We asked her three questions for an article on sustainable innovations to be published in Italy.

EU Citizens’ Initiative for fair rules on NBT

The initiative to foster responsible¬†agricultural innovation in the EU was started by a group of young Master’s students¬†from eight EU member states, with backgrounds in food safety, food law, environmental studies, plant sciences, economics and biotechnology. They met at Wageningen University and joined forces to urge the European Commission to update the legislation on plant breeding.

The following is an excerpt from the news section of the Leopoldina website. Please note that DFG stands for the German research funding organization.

The Leopoldina, the Union of German Academies and the DFG have drafted recommendations for ensuring science-based regulation of genome edited plants in the EU. These recommendations include the amendment of European genetic engineering legislation.

Italy to edit quality foods

spaghettiThe research institute CREA is experimenting with CRISPR to improve Italian typical products. The project called BIOTECH is funded with 6 million euros from the Italian ministry of agriculture. Wheat, tomatoes, vines, fruits and more are on the menu, as reported by me in a 6-pages feature published in Le Scienze, the national edition of Scientific American. Continue reading
