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 witches' broom phytoplasma effector induces stunting by stabilizing a bHLH transcription factor in Ziziphus jujuba plants. [PDF]

New Phytol
Summary Phytoplasmas are specialized phloem‐limited bacteria that cause diseases on various crops, resulting in significant agricultural losses. This research focuses on the jujube witches' broom (JWB) phytoplasma and investigates the host‐manipulating activity of the effector SJP39.

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.
