Plants Can Now Make a Key Dairy Protein

Topic: Biology

Scientists at Hebrew University of Jerusalem discovered that plants can produce β-casein, a protein found in cow's milk. This breakthrough could lead to more sustainable dairy production without relying on animals.

Imagine growing the same proteins that give milk its nutrition and texture inside plants instead of cows. Researchers at the Hebrew University of Jerusalem took a significant step towards this goal by finding an unexpected way plant seeds can make β-casein, one of the major proteins in cow's milk.

The study was led by Prof. Oded Shoseyov and his team, including lead author Almog Ozeri. They used Arabidopsis seeds to produce bovine β-casein, a protein found in cow's milk. The researchers expected the protein to build up inside specialized storage vacuoles but instead discovered that it formed previously unrecognized structures associated with tiny oil bodies.

This breakthrough could help overcome a major hurdle in producing real dairy proteins without cows. The team's discovery suggests that plants may possess an alternative route for storing complex recombinant proteins, making plant molecular farming more efficient.

Why It Matters

As the global demand for dairy grows, finding sustainable ways to produce authentic dairy proteins is crucial. This breakthrough could lead to a reduction in greenhouse gas emissions and water consumption associated with livestock farming.
