Nucleotide-binding leucine-rich repeat (NLR) receptors mediate pathogen effector-triggered immunity (ETI) in plants, and a subclass of NLRs are hypothesized to function at the plasma membrane (PM). However, how NLR traffic and PM delivery are regulated during immune responses remains largely unknown. The rice NLR PigmR confers broad-spectrum resistance to the blast fungus Magnaporthe oryzae.

Lacking an adaptive immune system, plants rely on innate immunity comprising two main layers: PAMP-triggered immunity (PTI) and effector-triggered immunity (ETI), both utilizing Ca influx and reactive oxygen species (ROS) for signaling. PTI, mediated by pattern-recognition receptors (PRRs), responds to conserved pathogen- or damage-associated molecular patterns. Some pathogens evade PTI using effectors, triggering plants to activate ETI.

Article Synopsis
- Carrots are a widely consumed and nutritious vegetable but suffer from significant yield losses due to a fungal disease called leaf blight, caused by Alternaria dauci.
- This study reports improved genome assemblies for both carrots and the fungal pathogen, enhancing our understanding of their genetic makeup and the dynamics during infection.
- The research highlights the interaction between carrot defense mechanisms and the pathogen's strategies, providing insights that can help improve carrot resistance to leaf blight in the future.
