Features
Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High-temperature injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to high temperature. Oppositely, grain yields in rice plants are often reduced by exposure to low temperature. Unexpected climate change, such as abnormally hot or cool summer temperatures, have occurred repeatedly during recent years. This method indicates that an appropriate use of specific phytohormones, such as auxin and GA, may promote stress tolerance and adaptation to abiotic stresses.

Targeted Application(s)/Industry
These potentially novel functions of the classical phytohormones will be important sustainable agriculture in the face of global climate change.
