Chinese Jujube witches' broom phytoplasmas inhibit ZjBRC1-mediated abscisic acid metabolism to induce shoot proliferation

Chinese jujube (Ziziphus jujuba Mill.), an important species in the Rhamnaceae family, has been cultivated in China for over 7,000 years and is vulnerable to Jujube witches' broom (JWB) disease. This disease, caused by the JWB plant pathogen, leads to overgrowth of axillary buds, affecting plant health and yield.Previous studies identified two JWB effectors, SJP1 and SJP2, which disrupt ZjBRC1-mediated auxin flux, inducing lateral bud outgrowth. Despite these discoveries, the complete pathogenesis of JWB remains largely unknown. Understanding the interactions between jujube plants and JWB phytoplasmas, particularly the role of secreted proteins in affecting plant growth regulators, is crucial.In July 2023, Horticulture Research published a research article titled "Haplotype analyses reveal novel insights into tomato history and domestication driven by long-distance migrations and latitudinal adaptations."In this study, tissue-specific transcriptional reprogramming was employed to ...
