The pathogenic effector PHYL1_JWB interacts with ZjCURT1A to mediate jujube witches' broom-induced photosynthesis impairment of jujube trees. [PDF]

Plant J
SUMMARY Photosynthesis impairment and the accompanying leaf yellowing represent a prominent and physiologically critical symptom of phytoplasma infection. However, the underlying molecular mechanisms remain poorly understood. In this study, we identified the Jujube Witches' Broom pathogenic effector PHYL1JWB, which was previously reported to induce ...

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 (

Integrative chromosome-scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma. [PDF]

Plant Genome
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 ...

Characterization of an amylase produced by aTrichoderma harzianumisolate with antagonistic activity againstCrinipellis perniciosa, the causal agent of witches’ broom of cocoa [PDF]

FEMS Microbiology Letters, 2000
An isolate of Trichoderma harzianum showing antagonistic activity against Crinipellis perniciosa, the causal agent of the witches' broom disease of cocoa, produces substantial amounts of hydrolytic enzymes. An amylase purified from isolate 1051 had a molecular mass of about 68.7 kDa.

Beyond Destabilizing Activity of SAP11-like Effector of Candidatus Phytoplasma mali Strain PM19

Microorganisms, 2022
It was shown that the SAP11 effector of different Candidatus Phytoplasma can destabilize some TEOSINE BRANCHES/CYCLOIDEA/PROLIFERATING CELL FACTORs (TCPs), resulting in plant phenotypes such as witches’ broom and crinkled leaves.
