Defense against phytopathogens relies on efficient antimicrobial protein secretion mediated by the microtubule-binding protein TGNap1
Defining plant defense machinery against pathogens is significant in cell biology and crop yield. TGNap1, a TGN and microtubule-binding protein, is required for defense and efficient anti-microbial protein secretion, linking secretion and cytoskeleton.

Dynamic changes of the Prf/Pto tomato resistance complex following effector recognition
Both plant and animals utilize resistant proteins to recognise pathogens. In this work the authors illustrate how bacterial perception by a tomato resistant protein is communicated in order to protect plants against pathogens.

Geminiviruses employ host DNA glycosylases to subvert DNA methylation-mediated defense
Plants tightly regulate DNA methylation to regulate gene expression. Here, the authors show that the tomato yellow leaf curl China virus βC1 protein interacts with plant DNA glycosylases to promote demethylation of viral DNA and promote virulence.

Jasmonate response decay and defense metabolite accumulation contributes to age-regulated dynamics of plant insect resistance
Immunity deteriorates with age in animals but less is known about how aging affects immunity in plants. Here, Maoet al. show that responsiveness to the major insect defense hormone JA declines as plants age, but insect resistance still increases as plants accumulate secondary metabolites such as glucosinolates.

Plant immune response to pathogens differs with changing temperatures
Plants have two mechanisms to respond to infection; pattern-triggered immunity detects conserved microbial compounds, whereas effector-triggered immunity recognizes proteins secreted by pathogens. In this study, Cheng et al. report that temperature determines which of these immune systems is preferentially induced.
