Agricultural Sciences: Yesterday, Today, and Tomorrow

Charles Valentine Memorial Lecture, 20 Nov. 2024 (C.S. Prakash, Lisa Ainsworth, Anastasia Bodnar, and Kate Tully)

I want to highlight a lecture recently given by one of the most influential scientists in the international debate on GMOs and gene editing in agriculture. Born in India, C. S. Prakash lives and works in the U.S. and has been elected a fellow of the American Association for the Advancement of Science (AAAS). His lecture, delivered at the AAAS Center for Scientific Evidence in Public Issues, traces the progress made over the past sixty years in the field of global food security—i.e., meeting the growing demand for food from the world’s population.

Eco-vandals target gene-edited Chardonnay in Italy

On the night of February 12-13, unknown vandals broke into a small experimental vineyard at the University of Verona in northern Italy to uproot Chardonnay vines that had been gene-edited to resist a fungal infection. Last September, the launch of this field trial was celebrated by researchers, producers, and prominent politicians—including Agriculture Minister Francesco Lollobrigida—because it was a point of pride for the country (the first field with gene-edited vines in Europe) and a step toward healthier, more sustainable viticulture, less reliant on fungicides. Anti-science belligerence strikes again: two experimental fields have been launched in Italy, and both have been attacked.

A for Avocado, B for Banana, C for CRISPR Cannabis

As 2025 starts, where does CRISPR stand in transforming agriculture? The Innovative Genomics Institute has provided a snapshot of the state of the art, and (despite the wait for new European regulations), things are moving forward. Let’s take a closer look.

Atomic spaghetti and mutagenesis B.C. (before CRISPR)

Before the advent of genome editing and GMOs, mutagenesis was achieved through radiation. This technique was also used to modify varieties of durum wheat, which, through crossbreeding, contributed to the production of pasta consumed in Italy (see this old statement made by Norberto Pogna to Nature Biotechnology). The term “atomic spaghetti” is sometimes invoked in debates on agricultural biotechnology to highlight how modern techniques are vastly more precise than those of the past. However, few people are aware of the full complexity of this story.

Fall and Rise: Italy’s Journey from GMOs to CRISPR

Italy has long been one of the most hostile countries toward GMOs, to the point of shutting down research in this field. Today, however, it stands among the most active EU members in testing New Genomic Techniques. How did this transformation happen? EMBO Reports features insights from some of the Italian scientists who have championed the defense of GMOs and the revival of experimental fields. Happy reading!

CRISPR hits tomato’s sweet spot

Recolored tomatoes, as in this cover. Enriched with vitamin D, such as those developed with the help of Italian scientists. Resistant to parasitic plants (broomrapes), like those being studied also in Italy. Redomesticated tomatoes, as if it were possible to rewind and restart the film of domestication at an accelerated speed. Even hot tomatoes. There is no doubt that CRISPR is making waves with this fruit so central to our cuisine and so important to the global economy (186 million tons are produced worldwide). The latest addition is the extra-sweet tomato, which had the honor of being featured in a paper in Nature.

CRISPR Chardonnay – Italy Doubles Up

The University of Verona’s edited vines are already in the field, and soon it could be the turn of the Edmund Mach Foundation and CREA-CNR. Once again, the focus is on Chardonnay, edited to resist downy mildew (with a double knock-out approach) or powdery mildew. I spoke with the key figures of this new chapter in Italian research: Mario Pezzotti, Sara Zenoni, Umberto Salvagnin, Riccardo Velasco, and Vittoria Brambilla. Returning to write for Nature Biotechnology is a joy for me, especially because this time, Italy is leading the way in innovation rather than holding it back, as in the past. Prosit!

CRISPR vines make their field debut in Italy

Where ag genetics goes (in Italy and beyond)

Four intense days of talks and discussions on the present and future of agricultural genetics. We will be there at the round table “Social impact of plant biotechnologies: challenges and opportunities” (12 September afternoon). See the full program here.

Meet Vittoria Brambilla: they tried to destroy it, but her CRISPR field lives on

The start of the first field trial with an edited plant had been greeted with joy by Italian scientists (here is the announcement in Nature Italy). However, less than two months after planting, unknown persons vandalized the harmless rice plants, Science reported. Fortunately, all was not lost: some plants survived, and with them the hope of completing this experiment and starting new ones. We talked about this with Vittoria Brambilla, who together with Fabio Fornara developed the edited rice at the University of Milan and obtained permission to study it outdoors to see how resistant it is to a fungal infection (rice blast). Please find the interview on the Italian site Agriscienza.
