Names
Ca. Phytoplasma ziziphi
Abstract
Peony (Paeonia suffruticosa Andr.), belonging to family Paeoniaceae, is an important medicinal and ornamental plant. During August of each year from 2016 to 2023, peony plants at Heze city were found to exhibit leaf yellows symptoms. The incidence rate of the symptomatic plant was recorded from 10% to 30% in four peony gardens with about 200 acres. Total DNA was extracted from 0.10 g fresh plant leaf tissues from 24 symptomatic and 8 asymptomatic samples using rapid plant genomic DNA isolation

Molecular Identification of ‘Candidatus Phytoplasma malaysianum’-Related Strains Associated with Areca catechu Palm Yellow Leaf Disease and Phylogenetic Diversity of the Phytoplasmas Within the 16SrXXXII Group

Names
Ca. Phytoplasma malaysianum
Abstract
Areca catechu palm is an important cash plant in Hainan Island of China and also in the tropical regions of the world. A. catechu palm yellow leaf (AcYL) disease caused by phytoplasmas is a devastating disease for plant production. In the study, the phytoplasmas associated with the AcYL disease were identified and characterized based on their conserved genes, and genetic variation and phylogenetic relationship of the phytoplasma strains in the 16SrXXXII group were demonstrated. The results indi

Molecular Identification and Characterization of Two Groups of Phytoplasma and Candidatus Liberibacter Asiaticus in Single or Mixed Infection of Citrus maxima on Hainan Island of China

Names
Liberibacter Ca. Liberibacter asiaticus
Abstract
The pathogens associated with citrus Huanglongbing symptoms, including yellowing and mottled leaves in Citrus maxima, an important economic crop on Hainan Island of China, were identified and characterized. In the study, detection, genetic variation and phylogenetic relationship analysis of the pathogens were performed based on 16S rRNA and β-operon gene fragments specific to phytoplasma and Candidatus Liberibacter asiaticus. The results indicated that the pathogens—such as phytoplasma strains o
