What to know about Wheat gene behind Hessian fly resistance cloned after 50-year search

Researchers at the University of Maryland have successfully cloned the H13 gene in wheat, which provides resistance to the Hessian fly. The study demonstrates how the gene interacts with larval saliva proteins to trigger a defense mechanism that starves and poisons the pests.

What happened

Wheat gene behind Hessian fly resistance cloned after 50-year search Robert Egan Senior Editor Researchers at the University of Maryland and their collaborators have cloned a gene that makes wheat resistant to feeding by Hessian fly larvae and demonstrated…

Why it matters

The research breaks through a longstanding barrier to understanding and engineering pest resistance in wheat.

Common ground

It is described in a research paper published Aug.

Perspective signals
