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
