Trichoderma derived emodin competes with ExpR and ExpI of Pectobacterium carotovorum subsp. Carotovorum to biocontrol bacterial soft rot.

Emodin from Trichoderma asperellum LN004 as QSI can compete to bind both ExpI and ExpR proteins, interfering with the QS of Pcc and reducing the production of virulence factors. The first molecular mechanism reveals the ability of emodin as a QSI to competitively inhibit two QS proteins simultaneously. This article is protected by copyright. All rights reserved.
