Essential virulence proteins of corn smut discovered

To infect its host plant maize, the fungal parasite Ustilago maydis uses a complex of seven proteins. Numerous findings reveal an essential role of the complex in causing disease and suggest a widespread occurence in fungal ...

Equipping crop plants for climate change

Biologists at Ludwig-Maximilians-Universitaet (LMU in Munich) have significantly enhanced the tolerance of blue-green algae to high light levels—with the aid of artificial evolution in the laboratory. 

How plants find their symbiotic partners

What would it be like to produce fertilizer in your own basement? Leguminous plants, like peas, beans and various species of clover, obtain the organic nitrogen they need for their growth from symbiotic soil bacteria via ...

Healthy plants appear to carry bacteria in their cells

International experts have described for the first time how healthy plants appear to carry bacteria in their cells, opening a new avenue of research to improve future plant health and propagation efforts—including food ...

Scientists identify networks for spikelet formation in barley

Organ development in plants mostly occurs through combinatorial activity of so-called meristems. Meristems are plant cells or tissues that give rise to new organs, similar to stem cells in human—including spikelets. Spikelets ...

A pioneering study: Plant roots act like a drill

In an interdisciplinary research project carried out at Tel Aviv University, researchers from the School of Plant Sciences affiliated with the George S. Wise Faculty of Life Sciences collaborated with their colleagues from ...

How nitrate regulates gene expression in legumes

Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful (Figure 1), but precisely how nitrate presence controls nodule formation ...
