TLDR
The latest advances in the understanding of the cell biology of biotrophic interactions between plants and their eukaryotic filamentous pathogens are summarized based on in planta analyses of effectors.Abstract:
Live-cell imaging assisted by fluorescent markers has been fundamental to understanding the focused secretory 'warfare' that occurs between plants and biotrophic pathogens that feed on living plant cells. Pathogens succeed through the spatiotemporal deployment of a remarkably diverse range of effector proteins to control plant defences and cellular processes. Some effectors can be secreted by appressoria even before host penetration, many enter living plant cells where they target diverse subcellular compartments and others move into neighbouring cells to prepare them before invasion. This Review summarizes the latest advances in our understanding of the cell biology of biotrophic interactions between plants and their eukaryotic filamentous pathogens based on in planta analyses of effectors.read more

Fungal Effectors and Plant Susceptibility
Libera Lo Presti,Daniel Lanver,Gabriel Schweizer,Shigeyuki Tanaka,Liang Liang,Marie Tollot,Alga Zuccaro,Stefanie Reissmann,Regine Kahmann +8 more
TL;DR: This review describes the effector repertoires of 84 plant-colonizing fungi and focuses on the mechanisms that allow these fungal effectors to promote virulence or compatibility, discuss common plant nodes that are targeted by effectors, and provide recent insights into effector evolution.

TL;DR: It is argued that much of the empirical evidence, in particular that derived from recent functional genomics, is at odds with many of the mechanistic assertions surrounding Si's role, and proposes a working model, which is proposed, the 'apoplastic obstruction hypothesis', which attempts to unify the various observations on Si's beneficial influences on plant growth and yield.

TL;DR: It is argued that nascent fungal infections will cause increasing attrition of biodiversity, with wider implications for human and ecosystem health, unless steps are taken to tighten biosecurity worldwide.

Pathogen population genetics, evolutionary potential, and durable resistance
TL;DR: A flexible framework to predict the evolutionary potential of pathogen populations based on analysis of their genetic structure is proposed and pathogens that pose the greatest risk of breaking down resistance genes have a mixed reproduction system, a high potential for genotype flow, large effective population sizes, and high mutation rates.

Direct interaction of resistance gene and avirulence gene products confers rice blast resistance
TL;DR: It is reported here that transient expression of AVR‐Pita176 inside plant cells results in a Pi‐ta‐dependent resistance response, and data suggest that the AVR-Pita 176 protein binds directly to the Pi‐TA LRD region inside the plant cell to initiate a Pi-ta‐mediated defense response.
