A new role for cytokinin plant hormones

When plants, including crops, are exposed to environmental stresses such as drought or high salinity, abscisic acid (ABA), a stress-responsive hormone is synthesized to induce a protective response. At the same time, the ...

Hemp 'goes hot' due to genetics, not growing conditions

As the hemp industry grows, producers face the risk of cultivating a crop that can become unusable—and illegal—if it develops too much of the psychoactive chemical THC. Cornell University researchers have determined that ...

Without this, plants cannot respond to temperature

UC Riverside scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width ...

Unlocking the rice immune system

A bacterial signal that when recognized by rice plants enables the plants to resist a devastating blight disease has been identified by a multi-national team of researchers led by scientists with the U.S. Department of Energy ...

On guard against drought

Identification of a gene that helps plants to conserve water under drought conditions will bring biologists closer to understanding how plants tolerate drought. Researchers, led by Takashi Kuromori at Japan's RIKEN Plant ...

Hormone keys plant growth or stress tolerance, but not both

Plants that grow well tend to be sensitive to heat and drought, and plants that can handle those stresses often have stunted growth. A Purdue University plant scientist has found the switch that creates that antagonism, opening ...
