Researchers discover a master regulator of plant immunity

The demonstration that a regulatory protein linked to stress responses in plants also serves as a master switch for anti-pathogen immunity could help breeders develop more pest-resistant and climate-resilient crops.

Diphthamide is an Achilles heel shared by both plants and animals

The biomolecule diphthamide is essential for the proper formation of proteins in cells. When humans are infected with diphtheria, diphthamide is altered by the diphtheria toxin so that life-threatening complications can arise ...

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 ...
