Discovery of family of hormones may be key to increased crop yields

Crops often face harsh growing environments. Instead of using energy for growth, factors such as disease, extreme temperatures, and salty soils force plants to use it to respond to the resulting stress. This is known as the ...

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 ...

Increasing crop resistance to pathogens

We all know that animals have an immune system - but plants have systems to fight infection too. Plant cells have receptor proteins which bind with parts of a pathogen. These receptor proteins are located on the surface of ...

PLoS Genetics 2009 maize genome collection

Maize is an important crop in many countries of the world. It is widely used for human consumption, animal feed, and industrial materials. It also is considered an exemplar plant species for studying domestication, molecular ...

Wearable sensors for advanced plant phenotyping

In response to increasing global food demands, improving crop yields through efficient phenotyping is imperative. Optical imaging-based phenotyping has markedly progressed plant breeding and crop management, yet encounters ...

Plant responses to climate are lagged

Two in five of the world's plant species are at risk of extinction. In the face of climate change, understanding why certain plant species are vulnerable to extinction while others prevail is more urgent than ever before. ...
