▪ Abstract During the past decade, research has yielded new knowledge about the plant and
insect host ranges, geographical distribution, and phylogenetic relationships of …

Numerous yellows-type diseases of plants have been associated with wall-less prokaryote
pathogens–phytoplasmas over the last 40 years. These pathogens are not grown in axenic …

Several economically relevant phytoplasma-associated diseases are described together
with an update of phytoplasma taxonomy and major biological and molecular features of …

SUMMARY Taxonomy: Superkingdom Prokaryota; Kingdom Monera; Domain Bacteria;

Aster yellows (AY) group (16SrI) phytoplasmas are associated with over 100 economically
important diseases worldwide and represent the most diverse and widespread phytoplasma …

A summary of the research carried out on phytoplasma-associated diseases 50 years after
their discovery is presented. The great majority of this research was devoted to classification …

Since the first report of existence of phytoplasma disease in 1874 in India, now more than
172 plant species are reported to be the host of ten different groups of phytoplasmas. The …

Apple proliferation (AP), pear decline (PD) and European stone fruit yellows (ESFY) are
among the most economically important plant diseases that are caused by phytoplasmas …

Elm yellows group (16SrV) phytoplasmas, which are associated with devastating diseases
in elm, grapevine, blackberry, cherry, peach and several other plant species in America …

Plant pathogen presence is very dangerous for agricultural ecosystems and causes huge
economic losses. Phytoplasmas are insect-transmitted wall-less bacteria living in plants …
