Quorum-quenching endophytic bacteria inhibit disease caused by Pseudomonas syringae pv. syringae in Citrus cultivars.

Two strains of 64 endophytic bacteria, Bacillus cereus Si-Ps1 and Pseudomonas azotoformans La-Pot3-3, isolated from Citrus sinensis and C. sinensis var. Thomson's leaves, respectively, reduced N-acyl homoserine-based quorum sensing in bioindicator strain Pseudomonas syringae pv.
