Jujube Witches' Broom Phytoplasma Effectors SJP1/2 Manipulate the ZjTCP2-ZjTCP1 Cascade to Repress Leaf Cell Proliferation in Jujube. [PDF]

Mol Plant Pathol
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 (

Machine learning-driven GWAS uncovers novel candidate genes for resistance to frosty pod rot and witches' broom disease in cacao. [PDF]

Plant Genome
Abstract Cacao (Theobroma cacao), the source of chocolate, is threatened by devastating diseases like frosty pod rot (FPR) and witches' broom disease (WBD), impacting global production and farmer livelihoods. Here, we employ a machine learning‐driven genome‐wide association study to dissect the genetic architecture of disease resistance and ...

A new pest recorded in Italy: The South African citrus thrips, Scirtothrips aurantii (Thysanoptera: Thripidae)

EPPO Bulletin, EarlyView.
Abstract The South African citrus thrips, Scirtothrips aurantii Faure, 1929, has been recorded in Italy for the first time. This species was recently reported in Spain and Portugal. Its presence has been confirmed in the major citrus‐growing area of Catania province (Sicily), infesting citrus trees. S. aurantii is currently included in the EPPO A1 List

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 ...

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...

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

Detection and characterisation of phytoplasma strains associated with field bindweed witches’ broom disease in Iran

, 2018
During 2013–2015 surveys in Fars, Lorestan and Yazd provinces (Iran), a field bindweed witches’ broom (FBWB) disease was observed. The main symptoms were reduction of leaves size, yellowing, internode shortening, witches’ broom and stunting. The agent of

Molecular Detection and Multilocus Sequence Analysis of ‘Candidatus Phytoplasma Solani’ Strains Infecting Neighbouring Potato and Sugar Beet Fields in Southern Germany

Journal of Phytopathology, Volume 173, Issue 6, November/December 2025.
ABSTRACT Phytoplasmas were detected in potato tubers and sugar beet roots in neighbouring fields in Southern Germany using quantitative PCR. Infected potato plants showed phytoplasma‐associated symptoms including yellowing, upward leaf rolling, aerial tubers and early senescence.
