Phytoplasma Identity and Disease Etiology [PDF]

open access: yesPhytopathology®, 1998
Many plant diseases believed to be caused by phytoplasmas were described before phytoplasma groups were delineated through molecular analyses. It is now possible to assess the relationships between phytoplasma identity or classification and specific plant diseases.

From sequences to species: Charting the phytoplasma classification and taxonomy in the era of taxogenomics

open access: yesFrontiers in Microbiology, 2023
Phytoplasma taxonomy has been a topic of discussion for the last two and half decades. Since the Japanese scientists discovered the phytoplasma bodies in 1967, the phytoplasma taxonomy was limited to disease symptomology for a long time.
