The Moniliophthora roreri Effector MrB1 Affects Cellular Homeostasis and Induces Genotype‐Dependent Necrosis in Theobroma cacao

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
The effector MrB1 induces cytotoxicity in plant cells through oxidative stress, membrane damage, protein folding collapse, and energy failure. These alterations compromise cellular integrity and result in necrosis. ABSTRACT Frosty pod rot (FPR) is an invasive disease responsible for severe yield losses of cacao trees.

Elucidating R‐gene‐mediated resistance to wheat dwarf virus in Triticum aestivum genotypes

Annals of Applied Biology, Volume 188, Issue 3, Page 947-961, May 2026.
This study investigates R‐gene‐mediated resistance to wheat dwarf virus (WDV) among different wheat genotypes. Following inoculation with Psammotettix alienus (leafhoppers) and the subsequent appearance of characteristic symptoms such as yellowing and dwarfing, phenotypic responses were evaluated alongside molecular analyses, including quantification ...

Jujube Witches' Broom Phytoplasma Effectors SJP1/2 Manipulate the ZjTCP2‐ZjTCP1 Cascade to Repress Leaf Cell Proliferation in Jujube

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
SJP1 and SJP2, two effectors secreted by JWB phytoplasmas, inhibit jujube leaf cell proliferation through manipulating a cascade involving ZjTCP2 and ZjTCP1, two TCP transcription factors from distinct subfamilies. ABSTRACT Leaf development into the final size is spatiotemporally regulated by cell proliferation and expansion. The jujube witches' broom (

Molecular Mechanism of ZjWRKY40‐zju‐miR157 Module Regulating Phytoplasma Tolerance in Jujube

Molecular Plant Pathology, Volume 27, Issue 2, February 2026.
SJP4JWB regulated the ZjWRKY40‐zju‐miR157 module to modulate the differential phytoplasma tolerance between phytoplasma‐susceptible genotype Fu and phytoplasma‐tolerant genotype T13. ABSTRACT Phytoplasma (‘Candidatus Phytoplasma’), a bacterial pathogen, is a significant plant health concern worldwide, resulting in substantial economic losses. In jujube
