Kind: research · Impact: low

## In brief

- Nature Communications published the study online on 14 November 2026 (doi:10.1038/s41467-026-79480-y).
- The authors develop a dual-responsive fluorescent probe intended to resolve the H2O2–salicylic acid interaction.
- The abstract describes hydrogen peroxide and salicylic acid interaction as important for plant stress responses, and the study examines PTI and ETI.

## Why it matters

The work offers a chemogenetic tool for studying how hydrogen peroxide and salicylic acid interact in plant immune signalling, which could help researchers map these pathways more precisely.
