摘要

金丝桃（Trachyspermum ammi）是一种传统药用植物，被广泛用于治疗人类的各种疾病。在 2022 年的一次调查中，在博帕尔观察到了与植原体疾病相关的黄化症状。在有症状的植物叶片样本中，使用植原体特异性引物通过直接和嵌套 PCR 检测到了该疾病。对可疑的 ~ 1.2 kb 扩增扩增子进行了测序，并将其提交到 GenBank，登录号为 OQ216747。该植原体分离株与翠菊黄化植原体分离株（"Candidatus Phytoplasma asteris"；16SrI 组）的 16 S 核糖体 RNA 基因显示出最高 99.42% 的序列同一性和系统发育关系。这是首次报道'Ca.asteris' (16SrI) 与 T. ammi 的黄化病有关。

First report of ‘Candidatus Phytoplasma asteris’ (16SrI) associated with yellows disease of Trachyspermum ammi from India

Trachyspermum ammi is a traditional medicinal plant and is widely used for curing various diseases in humans. During a 2022 survey, yellowing symptoms associated with phytoplasma disease were observed in Bhopal. The disease was detected by direct and nested PCR using phytoplasma-specific primers in symptomatic plant leaf samples. The suspected ~ 1.2 kb amplified amplicons were sequenced and submitted in GenBank under accession number OQ216747. The phytoplasma isolate showed the highest 99.42% sequence identity and phylogenetic relationships with the 16 S ribosomal RNA gene of an isolate of aster yellows phytoplasma (‘Candidatus Phytoplasma asteris’; 16SrI group). This is the first report of ‘Ca. P. asteris’ (16SrI) associated with the yellows disease of T. ammi.

期刊介绍： Australasian Plant Disease Notes is an international journal for publication of short reports from all countries which describe original research that transcends national boundaries. All aspects of plant pathology are covered including new geographical records of diseases or pathogens, new pathogens or pathogen strains, taxonomic papers, quarantine notes, disease management and diagnostic methods. Australasian Plant Disease Notes is a publication of the Australasian Plant Pathology Society.
