Pattern recognition receptors in plants

How pathogen signals perceived by receptor kinases activate plant immunity is not fully understood. Here the authors show that phosphocoding of a shared phosphatase ensures signalling from growth and immune receptors to specific cellular responses.

Transgenic plants expressing both Ve1 and Ve2 conferred enhanced signaling and disease resistance in susceptible potato in a race-specific manner, a step forward in generating disease resistant plants against Verticillium.

The U-box type ubiquitin ligase PUB44 positively regulates pattern-triggered immunity in rice. Here the authors identify a PUB44 substrate whose degradation is required for activation of the WRKY45 transcription factor upon immune elicitation.

Plant NLR proteins trigger immune responses upon recognition of pathogen effectors. Here the authors show that the integrated decoy domain of the rice NLR RGA5 can be engineered to trigger immune responses upon binding a non-cognate effector.

Pattern-triggered immunity is activated by recognition of microbe-derived structures by host pattern recognition receptors. Here the authors use a genotype-by sequencing approach to show that bacterial translation initiation factor 1 triggers PTI in Arabidopsis thaliana after recognition by the RLP32 receptor.
