The high-resolution structure of a filamentous flexible plant virus shows that there is structural homology between its coat protein and the nucleoproteins of an unrelated group of enveloped RNA animal viruses.
Structure/function studies of a plant pathogen effector in complex with a host disease resistance protein domain reveal the molecular basis for recognition and underpin future engineering of immunity in crops.
Expression of plant immune genes is controlled by the opposing actions of ubiquitin ligases and deubiquitinases that modify the master coactivator NPR1, thereby regulating its intrinsic transcriptional activity.
A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.
Genetic and biochemical analysis of two enzymes reveals that inositol pyrophosphate signaling molecules allow plants to sense and regulate cellular phosphate levels, and to take up more phosphate when needed.
