Cyborg botany: Scientists tap plants’ signals to turn crops into living sensors

Bengaluru: Imagine your houseplant sending a text: “I’m thirsty — could you water me?” Or a rice field alerting a farmer to disease before a single leaf shows damage. Researchers around the world are now working to make that real through an emerging field called cyborg botany.

The approach treats plants as living circuit boards by tapping directly into the complex biochemical signals they use to respond to their environment. Plants constantly react to two broad types of stress: biotic stress, such as pest infestations and disease, and abiotic stress, such as drought and extreme temperatures.

By reading those signals at the source, scientists aim to turn crops and houseplants into real-time sensors. The goal is early detection of water needs, nutrient deficiencies, and pathogen outbreaks — hours or days before visible symptoms appear.
