Abstract

In a survey in 2020, Salix babylonica trees displaying symptoms of phyllody, little leaves, and dieback were observed in Xinjiang province of China. Nested PCRs carried out using universal primer pairs for 16 S rRNA and tuf genes, detected the presence of phytoplasmas in symptomatic trees, while no amplification was found in symptomless trees. Blastn and phylogenetic analyses showed that detected phytoplasmas belong to the species ‘Candidatus Phytoplasma ziziphi’, ribosomal subgroup 16SrV-B. This is the first report of S. babylonica as plant host of ‘Ca. Phytoplasma ziziphi’, associated with phyllody disease in China.

柳：一个新的‘紫苏’寄主

在2020年的一项调查中，在中国新疆省观察到古巴柳树表现出叶根病、小叶和枯死的症状。使用通用引物对16个S rRNA和tuf基因进行巢式pcr，检测到有症状树中存在植物原体，而无症状树中未发现扩增。胚芽和系统发育分析表明，检测到的植物原体属于“Candidatus Phytoplasma ziziphi”，核糖体亚群16SrV-B。这是首次报道的古巴螺属植物寄主。中国与根瘤病相关的紫皮植物原体。
