TL;DR: iPhyClassifier is an interactive online tool capable of determining the species, group and subgroup of 'Candidatus Phytoplasma' of unknown samples using the 16S F2nR2 sequence and allowed us to identify two new tentative groups and the following tentative new subgroups among Latin American strains that were either previously unclassified or misclassified.

TL;DR: Because of their cryptic nature, phytoplasmas are difficult to manage; quarantine measures and insecticide sprays remain the most common control measures; however, integrated pest management techniques using beneficial insects, biotechnology, and plant resistance are emerging.

TL;DR: A method for accessing the chaperonin-60 (cpn60) gene sequence from a diverse array of ‘Ca.Phytoplasmas’ spp, providing rapid diagnosis and typing of phytoplasma infections, and the topology of a phylogenetic tree generated using cpn60 sequences was congruent with that reported for 16S rRNA-encoding genes.

TL;DR: The research showed that spiral cleaning has the potential to remove seeds that contain phytoplasma DNA in B. napus and Brassica rapa, and reports for the first time the detection of AY strains in seedling tissues of both Brassica species.

TL;DR: This is the first detection of MBS phytoplasma (MBSP) affecting native corn and the first molecular survey made in corn fields in Mexico to detect and characterize MBSP, and the potential evolutionary relationship between corn and MBSP is discussed.
