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.
