Researchers discovered that the closest wild relative of tomatoes manages salinity stress entirely differently than previously thought.
Given a changing climate and increasing soil salinity in many agricultural regions, it's more important than ever that researchers identify crops that can thrive in challenging conditions. Cultivated tomatoes, a staple in many diets, often struggle in salty soils. However, their wild relatives evolved to endure a variety of harsh environments.
A recent study explored salt stress tolerance in wild tomato species, setting the stage for further research into the genetic foundations of these traits. The insights gained could drive breeding efforts aimed at improving salinity tolerance in tomatoes and other crops, potentially expanding growing regions, stabilizing yields despite an unpredictable climate, and creating crops that require less water and resources.
Researchers focused on Solanum pimpinellifolium, the closest cousin of the cultivated tomato. Despite their small, cherry-sized fruits, these wild tomatoes offer substantial genetic diversity and stress resistance.
