Cocaine synthesized in a tobacco plant

A team of researchers at the Chinese Academy of Sciences, working with a colleague from Syngenta Jealott's Hill International Research Centre in the U.K., has developed a way to synthesize cocaine using a tobacco plant. The ...

Extreme salt stress triggers leaf movement

Plant leaves can cope with much higher salt concentrations than roots. The underlying mechanism may help to develop more salt-tolerant crops.

Metal nanoparticles serves as plant growth regulators

Engineered nanomaterials (EMs) negatively or positively affect plant growth and development attributed to their physiochemical properties, application, and concentrations. Previous studies have shown that ferroferric oxide ...

Polluted land can be planted with flowers and tobacco

Zinnia (popular ornamental flowers) and tobacco adapt to copper in the soil. They accumulate heavy metal in the roots and limit the transport of copper to the aerial parts of the plant: stem, leaves, and beyond. At the same ...

Antagonistic interactions of plant defense compounds

A combined defense of different chemical defense substances could result in a negative interaction and mutual detoxification, according to researchers at the Max Planck Institute for Chemical Ecology in a new study, appearing ...

Tobacco hawkmoths always find the right odor

A research team at the Max Planck Institute for Chemical Ecology has discovered how tobacco hawkmoths are able to detect odors that are important to them against a complex olfactory background. By looking at the specific ...

Unexpected benefits from food competitors

A research team at the Max Planck Institute for Chemical Ecology has found that gravid tobacco hawkmoths (Manduca sexta) show an unusual preference for Datura plants that are already infested with leaf beetles when laying ...
