NLRs guard metabolism to coordinate pattern- and effector-triggered immunity
The deubiquitinase PICI1 is identified as part of an immunity hub that coordinates pattern- and effector-triggered immunity and is involved in conferring broad-spectrum resistance to blast across different subspecies of rice.

Mutual potentiation of plant immunity by cell-surface and intracellular receptors
In Arabidopsis, two distinct types of immunity—that mediated by cell-surface receptors and that mediated by intracellular receptors—interact with and mutually enhance each other to provide effective defence against pathogens.

Pattern-recognition receptors are required for NLR-mediated plant immunity
Bacteria elicit two distinct immune responses in Arabidopsis thaliana, mediated by diverse signalling receptors but working in a synergistic manner.

A kiwellin disarms the metabolic activity of a secreted fungal virulence factor
A kiwellin protein in maize is found to inhibit the activity of the secreted enzyme chorismate mutase from a maize-infecting pathogenic fungus, suggesting a role for kiwellins in plant immunity.

MicroRNAs from the parasitic plant Cuscuta campestris target host messenger RNAs
A parasitic plant produces microRNAs that target host messenger RNAs, causing them to be processed into small interfering RNAs.

Defence at dawn
A remarkable example has been discovered of a plant tuning its immune defence against a pathogen. The tuning consists of maximal expression of the relevant genes at the time of day when attack is most likely. See Letter p.110
