DAVIS, California, Aug 6 — The shift is happening in a greenhouse, not a factory line. For the first time, genetically engineered lettuce and tobacco plants are producing animal myoglobin, the heme protein that has become the holy grail for alt-meat makers chasing the taste of the real thing.
The breakthrough is the product of extensive research across the plant biotechnology sector, a field that has been quietly building toward this moment for decades. Specific names of the scientists behind this particular first haven’t been released. But the infrastructure that made it possible is no secret.
Who’s building this
Leading research universities have been laying the groundwork. The University of California, Davis; Wageningen University & Research in the Netherlands; and institutions within Germany’s Max Planck Society sit at the forefront of plant genetic engineering. Their fundamental work spans gene editing, including CRISPR-Cas9 — the technology pioneered in the 2010s by Jennifer Doudna and Emmanuelle Charpentier — alongside plant metabolic engineering and synthetic biology.
The private sector has already proven the commercial end of this road. Impossible Foods and Beyond Meat use plant-based heme derived from soy leghemoglobin, a plant protein similar to myoglobin, in their products. That is consumer acceptance, demonstrated at scale. The step now being taken goes further: growing the animal version of that protein directly in plant tissue.
There is also the older guard. Agricultural biotechnology heavyweights Bayer Crop Science, formerly Monsanto, along with Corteva Agriscience and Syngenta, have poured billions into genetically modified crops engineered for pest resistance and herbicide tolerance — work that has reshaped global food systems since the 1990s.
Government money rounds out the ecosystem. The U.S. Department of Agriculture and the National Science Foundation provide significant funding for plant science research, fostering the environment where a first-time breakthrough like this can emerge.
What’s changing
Here is the trend underneath: convergence. Genetics, biochemistry, and agricultural science are being combined across universities, companies, and public agencies to translate laboratory discoveries into scalable solutions for sustainable protein production.
For decades, plant genetic engineering was mostly about defense — making crops resistant to pests and tolerant of herbicides. This development moves the field into entirely new territory: turning plants into bioreactors for animal proteins. The fact that the work spans academic institutions, private firms, and government-funded initiatives says something about how ambitious the goal is and how many hands are on deck.
The implications for sustainable protein are substantial. If plants can reliably produce animal myoglobin, the ingredient platform for meat alternatives changes — and the lessons learned from soy leghemoglobin’s commercial success suggest consumers are ready for it.
Watch this space. The first successful production of animal myoglobin in lettuce and tobacco is a laboratory milestone today, but the infrastructure behind it — the universities, the agribusiness giants, the government funding streams — has a track record of scaling up fast. The next move will be figuring out which crops, which methods, and which partners turn this from a breakthrough into an industry.
