Description
Zheng Chen and six colleagues characterize in 2026 a fatty peptide made by a soil bacterium that teaches tomato plants to defend themselves against bacterial wilt. The disease, caused by Ralstonia solanacearum, devastates tomato fields worldwide and resists chemicals. Chemical analysis identified the compound as a family of surfactin variants, some with fatty chains never before reported from this Bacillus species.
In pot trials the peptide delayed symptoms by four days and cut final disease levels by roughly a third. It did not kill the pathogen directly in dishes, so protection must run through the plant itself. Defense enzyme activity spiked within two days of treatment. Combined gene and chemistry profiling showed coordinated rewiring of stress hormones, water channels, and pigment pathways, which the authors present as proof of induced systemic resistance worth field testing.
