 News: New invention enables humans to 'talk' to plants using light

Researchers have ushered in a new era in plant science by creating a technology that brings the once-fictitious idea of human-plant communication to reality. This recently developed technology enables humans to ‘talk’ to plants and receive communication back from them, using light-based messaging. This incredible breakthrough was achieved by a team of scientists from the Sainsbury Laboratory Cambridge University (SLCU)

Researchers have ushered in a new era in plant science by creating a technology that brings the once-fictitious idea of human-plant communication to reality. This recently developed technology enables humans to ‘talk’ to plants and receive communication back from them, using light-based messaging. This incredible breakthrough was achieved by a team of scientists from the Sainsbury Laboratory Cambridge University (SLCU)

Initiating plant defense mechanisms

The experiments conducted by Alexander Jones’ research team at the university involved using light as a messenger to talk to plants. The light activates the natural defense mechanisms in tobacco plants (Nicotiana benthamiana), showcasing that light can be a stimulus triggering plants’ immune responses.

This implies that light, a universal medium of communication for humans, can now serve as a bridge for interspecies interaction between humans and plants.

Highlighter: Created to talk to plants

Before this discovery, the University of Cambridge team engineered fluorescent light-based biosensors that could visually communicate real-time cellular activities in plants, revealing dynamics of critical plant hormones and how plants react to environmental stresses, effectively allowing plants to ‘talk’ to humans.

The latest development, Highlighter, is a tool documented in PLOS Biology that uses specific light conditions to activate the expression of a target gene in plants, allowing humans to trigger defense mechanisms in plants.

Dr. Jones explains, “If we could warn plants of an impending disease outbreak or pest attack, plants could then activate their natural defense mechanisms to prevent widespread damage.
