Scientists create tomatoes that smell like popcorn using gene editing

by

Researchers in China have created tomatoes with a unique, popcorn-like smell through gene editing.

Scientists used the CRISPR gene-editing tool to change specific genes that control tomato flavor, resulting in plants that produce tomatoes with a remarkably strong and pleasant aroma.

This research focuses on maintaining the fresh taste and aroma of tomatoes, which tend to fade after they’re picked and shipped.

Gene-edited tomatoes produce popcorn-like aroma

The study, published by KeAi Publishing, found that the smell resembling popcorn is caused by higher amounts of a natural compound called 2-acetyl-1-pyrroline. This compound is also responsible for the pleasant aromas of fragrant rice and, of course, buttered popcorn.

Scientists altered the genes of tomatoes—specifically, they turned off two genes called SlBADH1 and SlBADH2—which usually prevent the plant from making strong-smelling compounds.

The gene-edited tomatoes were described as having a “popcorn-like” aroma.

When researchers disabled certain genes in tomatoes, the fruit produced a much stronger smell. Importantly, this didn’t affect how much fruit grew or its nutritional value.

The team believes this method could one day be used to make commercial tomatoes tastier and more attractive to consumers.

Researchers are continuing to develop new tomato varieties that have more complex and appealing flavors. They’re working to add a pleasant fragrance to popular tomato types, which could lead to tastier options for consumers.

Scientists have explored manipulating our senses before, even without gene editing. For example, back in 2025, a researcher in Britain developed a piece of music designed to make chocolate seem more delicious.
