Scientists have found a hidden superpower in a type of grass called Thinopyrum. This grass can help wheat plants tough it out against rust diseases, drought, and still keep their yields steady. The key is a special swap between two parts of the grass' DNA. This swap, called a chromosome translocation, is what gives the grass its super strength.

The grass, Agropyron glaiel, comes from a mix of two grass types. It was hard to use in wheat breeding before because we didn't know much about its DNA structure. But now, with this new discovery, we can see how one part of its DNA is super helpful. This part, from the St subgenome, gives wheat plants a big boost when combined with another part from the J subgenome.

In tests, wheat plants with this new DNA part did way better against rust diseases and drought. They kept their growth and water content up even in tough conditions. Over three years of field tests, these wheat plants showed they could keep up with other wheat plants in terms of performance and yield.

This new discovery is a big deal. It means we can make wheat plants stronger against multiple stresses. They can handle temporary water shortages during flowering without losing their performance. It's like giving wheat plants a secret weapon to face tough times.
