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 (

Molecular Mechanism of ZjWRKY40-zju-miR157 Module Regulating Phytoplasma Tolerance in Jujube. [PDF]

Mol Plant Pathol
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

Cassava Witches’ Broom Disease in Southeast Asia: A Review of Its Distribution and Associated Symptoms

Plants, 2023
Cassava witches’ broom disease (CWBD) is one of the main diseases of cassava in Southeast Asia (SEA). Affected cassava plants show reduced internodal length and proliferation of leaves (phyllody) in the middle and top part of the plant, which results in ...

Target degradation specificity of phytoplasma effector phyllogen is regulated by the recruitment of host proteasome shuttle protein. [PDF]

Mol Plant Pathol
Phyllogen‐mediated degradation specificity for MADS transcription factors (MTFs) is controlled by two steps: MTF‐binding affinity and recruitment of proteasome shuttle protein (this study, red arrow). Abstract Phytoplasmas infect a wide variety of plants and can cause distinctive symptoms including the conversion of floral organs into leaf‐like organs,

Candidatus Phytoplasma trifolii associated with faba bean phyllody in Jordan

, 2023
Faba bean phyllody associated with a high population of leafhoppers was observed in fields in Jordan Valley. Samples of affected plants were used to transmit the phyllody agent to faba bean by grafting. Empoasca decipiens was detected as potential insect
