Heat Stress Tolerance in Plants

Heat Stress Tolerance in Plants
This invention proposes a method to make plants more resistant to (repeated) heat
Technical Field
 Plant epigenetics
This is done by means of using microRNA156 (miRNA156) to increase heat stress
tolerance. miRNA156 is expressed under the control of a special heat-inducible

Previous solutions have been problematic for agriculture because of negative effects on
plant growth.
This invention solves this problem by expressing protective miRNA only after exposure
to heat stress, which means that plant growth is not affected under normal conditions.
This represents a major advantage over previous solutions.
This technology can therefore contribute to increased crop yields and associated
agricultural productivity.
