How plants' threat-detection mechanisms raise the alarm

New work led by Carnegie's Zhiyong Wang untangles a complex cellular signaling process that underpins plants' ability to balance expending energy on growth and defending themselves from pathogens. These findings, published ...

Toward customizable timber, grown in a lab

Each year, the world loses about 10 million hectares of forest—an area about the size of Iceland—because of deforestation. At that rate, some scientists predict the world's forests could disappear in 100 to 200 years.

Herbicide residues in soil affect hormone levels in crop plants

A new study finds that glyphosate residues in soil affect phytohormones in aboveground plant parts. Academy of Finland funded postdoctoral researcher Dr. Benjamin Fuchs investigates the effects of herbicide residues in soil ...

Plant smoke detectors evolve as hormone sensors

Wildfires are devastating, but they can also bring new life by clearing existing vegetation and allowing new plants to spring up. Many plants in fire-prone areas actually require exposure to fire for seeds to germinate. In ...

The pathway for producing ethylene

New research lays out the chemical steps used by a naturally occurring enzyme to convert a common chemical compound into ethylene—a plant hormone important for fruit ripening and an industrial chemical used in the production ...

How plant hormones control root growth

Plant roots can grow without limit. To do so, they need to balance the production of new cells via cell division and elongation. Plant hormones known as brassinosteroids play a key role in this balancing act. New work by ...
