Genetic analysis of ‘Candidatus Phytoplasma aurantifolia’ associated with witches’ broom on acid lime trees [PDF]

PeerJ, 2018
“Candidatus Phytoplasma aurantifolia” is associated with witches’ broom disease of lime in Oman and the UAE. A previous study showed that an infection by phytoplasma may not necessarily result in the physical appearance of witches’ broom symptoms in some

Genomic insights into the pathogenicity of a ‘Candidatus Phytoplasma asteris’ associated with Trema levigata witches’ broom disease in China [PDF]

BMC Plant Biology
Background Phytoplasma research encounters limitations due to the lack of availability of pure cultures of these microorganisms. In this study a culture-independent approach was employed to investigate the genome and pathogenic mechanisms of phytoplasma ...
