TL;DR: The trivial name 'phytoplasma' has been adopted to collectively name wall-less, non-helical prokaryotes that colonize plant phloem and insects, which were formerly known as mycoplasma-like organisms.

TL;DR: Aster yellows (AY) group (16SrI) phytoplasmas are associated with over 100 economically important diseases worldwide and represent the most diverse and widespread phy toplasmas group.

TL;DR: Transmission electron microscopic observation of ZC-affected tissues revealed the presence of bacteria-like organisms (BLOs) in the phloem of potato and tomato plants inoculated by grafting and psyllid feeding, which confirms the association of 'Ca. L. solanacearum' with potatoes affected by ZC in the United States, Mexico, and Guatemala.

TL;DR: The secY gene sequence is more useful genetic marker than the 16S rRNA gene for finer differentiation of closely related phytoplasma strains based on RFLP analysis with selected restriction enzymes and this study revealed two heterogeneous spc operons present in the phy toplasma clade.

TL;DR: A novel phytoplasma associated with a newly emerging disease in soybean, known as soybean stunt (SoyST), was found in 2002 in a soybean plantation in Alajuela Province, Costa Rica and represents a novel taxon, for which the name 'Candidatus Phy toplasma costaricanum' is proposed.
