Abstract
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.
期刊介绍：
The journal publishes papers on the infectious diseases of plants, damages caused by insects and deals with the basic aspects of chemical and biological protection. Within its field of interest additional topics such as resistance against plant diseases, and physiological, biochemical and molecular questions of plant resistance and susceptibility are also discussed. Publishes book reviews and advertisements.
