AI Article Synopsis
- Filamentous pathogens like oomycetes and fungi use various apoplastic effector proteins to infect plants, with over 177 identified proteins that can trigger cell death in plant cells.
- Many of these apoplastic cell death-inducing proteins (CDIPs) are crucial for the pathogens' ability to cause disease and can be recognized by plants as signals of infection.
- Recent research highlights how plants use specific proteins, called LRR-RLPs, to detect these CDIPs, leading to a better understanding of the plant defense mechanisms against these pathogens.
Article Abstract
Filamentous pathogens, such as phytopathogenic oomycetes and fungi, secrete a remarkable diversity of apoplastic effector proteins to facilitate infection, many of which are able to induce cell death in plants. Over the past decades, over 177 apoplastic cell death-inducing proteins (CDIPs) have been identified in filamentous oomycetes and fungi. An emerging number of studies have demonstrated the role of many apoplastic CDIPs as essential virulence factors. At the same time, apoplastic CDIPs have been documented to be recognized by plant cells as pathogen-associated molecular patterns (PAMPs). The recent findings of extracellular recognition of apoplastic CDIPs by plant leucine-rich repeat-receptor-like proteins (LRR-RLPs) have greatly advanced our understanding of how plants detect them and mount a defense response. This review summarizes the latest advances in identifying apoplastic CDIPs of plant pathogenic oomycetes and fungi, and our current understanding of the dual roles of apoplastic CDIPs in plant-filamentous pathogen interactions.

Article Synopsis
- Necrotrophic fungal pathogens like Sclerotinia sclerotiorum use specific proteins called cell death-inducing proteins (CDIPs) to promote their infection in plants, but the details of these proteins have not been well-studied.
- Researchers discovered that S. sclerotiorum secretes a protein called SsXyl2, which triggers cell death in host plants during infection, independent of its enzymatic activity.
- The study reveals that a plant protein (NbHIR2) interacts with SsXyl2 to enhance its effectiveness in causing cell death, and disruptions in this interaction can increase plant resistance, paving the way for developing more resistant crop varieties.

Botrytis cinerea is a necrotrophic fungal plant pathogen that causes grey mould and rot diseases in many crops. Here, we show that the B. cinerea BcCrh4 transglycosylase is secreted during plant infection and induces plant cell death and pattern-triggered immunity (PTI), fulfilling the characteristics of a cell death-inducing protein (CDIP).
