TL;DR

It is demonstrated that Pto, the first disease-resistance gene conferring recognition of a specific pathogen, phosphorylates Pst type III effector AvrPtoB at serine 335 site, which triggers the dissociation of the Prf immune complex, enhancing immune signaling and reducing bacterial pathogenicity.

PtRTP1, an Effector of Puccinia triticina, Contributes to Virulence in Wheat

Effector proteins are key virulence factors of obligate parasitic fungi during infection. Wheat leaf rust by Puccinia triticina is a widespread destructive disease drastically limiting wheat production, while the biological role of its effector is still elusive. PtRTP1 is a homolog of Uf-RTP1p, one of the earliest effe...

Multiple faces of Fusarium oxysporum effector protein Avr2

It was found that ΔspAvr2 transgenic tomato plants were attenuated in pathogen-associated molecular pattern-triggered immunity (PTI): flg22-induced growth inhibition, reactive oxygen species (ROS) production and callose deposition were all greatly alleviated in ΔspAvr2 plants.

A conserved COBL3-like protein promotes PDLP5-dependent callose accumulation to confer broad-spectrum plasmodesmata-mediated antiviral defense.

This study reveals a previously unknown role of COBRA-like proteins in PMAD and provides insight into how a plant viral MP sabotages PMAD through perturbing COBL3-PDLP5 interaction to facilitate virus spread through PD.

The putative four-transmembrane proteins RWTD1 and PRM1 differentially regulate sexual mating, symptom development, and teliospore formation in the sugarcane smut fungus

Sugarcane smut, caused by Sporisorium scitamineum, is one of the most devastating diseases of sugarcane worldwide, leading to severe yield losses and long-term agricultural impacts. Integral membrane proteins are essential components of plasma membranes, playing critical roles in molecular transport, signal transductio...
