Biologists Develop Nanosensors to Visualize Movements and Distribution of Plant Stress Hormone

Biologists at UC San Diego have succeeded in visualizing the movement within plants of a key hormone responsible for growth and resistance to drought. The achievement will allow researchers to conduct further studies to determine how the hormone helps plants respond to drought and other environmental stresses driven by the continuing increase in the atmosphere’s carbon dioxide, or CO2, concentration.

A paper describing their achievement appears in the April 15 issue of the scientific journal eLife and is accessible here.
