The defensive arsenal of plant roots

Plants adapt to their nutritional needs by modifying the permeability of their roots through the production or degradation of a cork-like layer called suberin. By studying the regulation of this protective layer in Arabidopsis ...

Researchers discover hormonal regulatory module for root elongation

In future, agricultural crop production will have to manage with less and less nitrogen fertilization. The goal must therefore be to increase nitrogen use efficiency so that yield levels can be kept stable. Plants respond ...

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 ...

Sensor that detects hydrogen peroxide in living plant cells

Hydrogen peroxide (H2O2) is commonly known as a bleaching and disinfecting agent. However, it is also constantly produced in living cells. Often as a byproduct of biological processes, sometimes intentionally, for example ...

High resolution image of Arabidopsis photosynthesis machine

For the first time, Umeå researchers have, with the help of cryogenic electron microscopy, succeeded in producing a high-resolution image of photosystem II—the central complex of photosynthesis—of the model plant Arabidopsis. ...

Study reveals how genes influence leaf architecture

A recent study, published in Nature Plants, by researchers at the Indian Institute of Science (IISc) has shed light on how simple leaves—one of the two basic forms of leaves—develop in a plant. The team included researchers ...

Chlorophyll fluorescence illuminates plant function

Chlorophyll, the green pigment found in plants and algae, emits faint red and far-red light when illuminated during photosynthesis. This so called chlorophyll-a fluorescence conveys information about the instantaneous rate ...
