Key Points

• Scientists created a tomato with a buttered popcorn-like aroma using gene-editing technology.
• The breakthrough was achieved by modifying specific genes in the tomato plant.
• The scent comes from 2-acetyl-1-pyrroline (2-AP), the same compound found in popcorn and fragrant rice.
• Researchers say the new tomatoes maintain normal growth, yield, and nutritional value.
• The innovation could improve tomato flavor and increase consumer appeal.

Summary

Scientists have developed a unique tomato variety that smells like buttered popcorn. Using advanced gene-editing technology, researchers altered specific genes responsible for aroma compounds, allowing the fruit to produce the same scent compound found in popcorn and fragrant rice. Experts say the development could help restore flavor in tomatoes that often lose aroma during storage and transport.

Scientists Create Popcorn-Scented Tomato

Researchers have developed a new tomato variety that emits the scent of buttered popcorn. The unusual aroma was achieved through CRISPR/Cas9 gene-editing technology, which allowed scientists to modify genes controlling aromatic compounds in the plant.

Although the tomatoes look normal, they release a sweet popcorn-like fragrance when handled or cut.

How the Aroma Was Created

The unique smell comes from 2-acetyl-1-pyrroline (2-AP), a natural compound responsible for the characteristic scent of popcorn and aromatic rice varieties such as basmati.

Scientists increased the levels of this compound by disabling two genes known as SlBADH1 and SlBADH2, which normally limit the production of aromatic molecules in tomatoes.

By altering these genes, researchers were able to significantly boost the fragrance of the fruit.

Flavor Improvement Without Affecting Quality

According to the researchers, the gene-edited tomatoes did not show major changes in plant height, fruit size, sugar content, or vitamin levels. This means the enhanced aroma was achieved without reducing crop yield or nutritional value.

Scientists believe this technology could help address the long-standing issue of tomatoes losing flavor during transportation and storage.

Potential Impact on Food Industry

Experts say the development could open the door to new flavor-enhanced fruits and vegetables. Researchers are now working to introduce the popcorn-like aroma trait into commercial tomato varieties, which could increase market value and consumer demand in the future.
