A bacterial effector targets the master immune regulator NPR1 ($)

Pathogenic microbes translocate effector molecules into plant cells that subvert host immune responses and promote disease. In a recent article published in Cell Host & Microbe, Chen et al. (2017) describe an exciting new interaction between the Pseudomonas syringae effector AvrPtoB and its cognate host target: the master immune regulator NPR1. Intriguingly, the authors show […]

Damage-associated signals differentially impact nematode parasitism

Roots must protect themselves from a diverse range of microbial and animal pests. To accomplish this, plants have evolved sophisticated signalling machinery to detect the presence of these pests or to quickly react to the damage that they cause. In a recent study, Shah et al. identified host receptor proteins that detect the damage-associated release […]

Small peptides, big importance: Small, secreted peptides as novel regulators of symbiosis and nutrient acquisition

It is becoming increasingly evident that small, secreted peptides (SSPs) are important regulators of plant development and responses to stress. Traditional gene prediction algorithms are biased toward larger coding sequences and have therefore been inadequate in the hunt for plant SSPs. To address this gap in knowledge, de Bang et al. developed improved SSP prediction […]
