Biologists develop nanosensors to visualize movements and distribution of plant hormone
Date:4/15/2014

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 at: http://elife.elifesciences.org/lookup/doi/10.7554/elife.01739

The plant hormone the biologists directly tracked is abscisic acid, or ABA, which plays a major role in activating drought resistance responses of plants and in regulating plant growth under environmental stress conditions. The ABA stress hormone also controls the closing of stomata, the pores within leaves through which plants lose 95 percent of their water while taking in CO2 for growth.

Scientists already know the general role that ABA plays within plants, but by directly visualizing the hormone they can now better understand the complex interactions involving ABA when a plant is subjected to drought or other stress.

"Understanding the dynamic distribution of ABA in plants in response to environmental stimuli is of particular importance in elucidating the action of this important plant hormone," says Julian Schroeder, a professor of biology at UC San Diego who headed the research effort. "For example, we can now investigate whether an increase in the leaf [CO2] concentration that occurs every night due to respiration in leaves affects the ABA concentration in stomatal cells."

The researchers developed what they call a "genetically-encoded reporter" in order to directly and instantaneously observe the movements of ABA within the mustard plant Arabidopsis.
