Salicylic acid (SA) is widely used in food storage, preservatives, additives, healthcare, and the pharmaceutical industry. However, various poisoning symptoms are frequently reported upon ingestion of a large amount of SA. Therefore, discovering new tools for sensing SA with fast, simple, and portable performance is imperative.

The impact of these VOCs on the mycelial growth of LC1, the causative agent of southern blight in , was evaluated using a double Petri-dish assay. The biocontrol efficacy of these VOCs was further assessed through leaf inoculation and pot experiments.

- Reactive oxygen species (ROS), reactive nitrogen species (RNS), and reactive sulfur species (RSS) are crucial for maintaining redox balance in the body, but imbalances can lead to health issues and diseases.
- Small-molecule fluorescent probes are useful tools for detecting these reactive species due to their high sensitivity, non-invasive nature, and ability to provide real-time measurements.
- The review focuses on the development of rhodamine-based fluorescent probes since 2016, discussing their design, mechanism of action, and applications in biological research.
Introduction: Southern blight, caused by , poses a serious threat to the cultivation of , a plant with significant medicinal value. The overreliance on fungicides for controlling this pathogen has led to environmental concerns and resistance issues. There is an urgent need for alternative, sustainable disease management strategies.

- Salicylic acid (SA) plays a crucial role in plant growth and immunity, aiding in pest control and food preservation, but research tools for studying its effects have been limited.
- Three newly developed Rh6G-based chemosensors demonstrate rapid and selective detection of SA, allowing for effective imaging of SA in plant tissues and better understanding of its physiological roles.
- The probes can also be applied in agricultural contexts to monitor SA levels, with visible results under UV light, addressing safety concerns due to SA's hazardous nature for sensitive individuals.
Article Synopsis
- * Researchers created and tested three new sensors (R1-R3) that can detect SA, using modified rhodamine-acylhydrazone compounds, with varying effectiveness.
- * The best sensor, R2 (3-hydroxyphenyl variant), detected SA at low concentrations (0.9 μM) quickly, indicating its potential for further research into SA's role in plant immunity.
