Phytoplasma effector SWP1 induces witches' broom symptom by destabilizing the TCP transcription factor BRANCHED1. [PDF]

Mol Plant Pathol, 2018
Phytoplasmas are insect-transmitted phytopathogenic bacteria, which secrete effector proteins that are often responsible for altering the plant morphology and behaviours of their vectors.

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 ...

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.

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.
