Hydroxylated monoterpenes (HMTPs) are differentially emitted by tomato (Solanum lycopersicum) plants resisting bacterial infection. We have studied the defensive role of these volatiles in the tomato response to bacteria, whose main entrance is through stomatal apertures. Treatments with some HMTPs resulted in stomatal closure and pathogenesis-related protein 1 (PR1) induction.

Article Synopsis
  • Biotic and abiotic stresses, such as drought and pathogens, limit crop productivity, leading to a need for sustainable agricultural strategies.
  • Plants respond to stress by closing their stomata and releasing volatile organic compounds, with ()-3-hexenyl butyrate (HB) identified as a key natural inducer that enhances stomatal immunity.
  • Research reveals that HB initiates defense responses independent of traditional pathways, improving water stress resilience and fruit productivity in tomatoes, and bolstering resistance against pathogen infections in both potato and tomato plants.

Benzothiadiazole (BTH) is a functional analogue of the phytohormone salycilic acid (SA) involved in the plant immune response. NahG tomato plants are unable to accumulate SA, which makes them hypersusceptible to several pathogens. Treatments with BTH increase the resistance to bacterial, fungal, viroid, or viral infections.

The volatile esters of (Z)-3-hexenol with acetic, propionic, isobutyric, or butyric acids are synthesized by alcohol acyltransferases (AAT) in plants. These compounds are differentially emitted when tomato plants are efficiently resisting an infection with pv. .
