Bean immune receptor triggers wasp-attracting defense
Filed: Jun 03, 2026 at 9:00 AM ET
Summary: Researchers identify an immune receptor in common beans that detects caterpillar feeding and activates a wasp-attracting signal.
WHO: Adam Steinbrenner’s team at the University of Washington
WHAT: Pinpointed a single immune receptor that orchestrates common bean anti-caterpillar defense signaling to attract parasitic wasps.
WHEN: Jun 03, 2026 at 7:15 AM ET
