摘要

在2013 - 2018年的调查中，在Shahjahnapur、Azamagarh的沙贾纳普尔(Shahjahnapur)的长爪食蟹(Cynodon dactylon)、Shahjahnapur的burmannii Oplismenus、Deoria的Arundo donax和Gorakhpur的Ocimum cannum均发现植物原体疑似症状。在Deoria地区，出现女巫帚症状的唐菖苣植物发病率最高(34%)。采用通用引物对(R16F2n/R16R2)进行巢式PCR，证实所有可疑样品均与植原体相关。进一步的BLASTn和系统发育分析显示，16SrXIV-A亚群植物原体与C. dactylon、O. burmannii有关联，16srxiv - b亚群植物原体与A. donax和O. cannum有关联。

Variability of phytoplasma associated with weeds grown in and around sugarcane crop in Uttar Pradesh, India

During survey from 2013 to 2018, Cynodon dactylon at Shahjahnapur, Azamagarh, Oplismenus burmannii at Shahjahnapur, Arundo donax at Deoria and Ocimum cannum at Gorakhpur were observed with phytoplasma suspected symptoms. The maximum disease incidence (34%) was recorded at Deoria District in case of A. donax plant with witches' broom symptom. The nested PCR using universal primer pairs (R16F2n/R16R2) confirmed the phytoplasma association with all the suspected samples. Further BLASTn and phylogenetic analysis of the sequences revealed the association of 16SrXIV-A subgroups phytoplasma with C. dactylon, O. burmannii and phytoplasma belonging to 16SrI-B subgroups with A. donax and O. cannum plants in the present study.
