Phytoplasmas: an update

A summary of the research carried out on phytoplasma-associated diseases 50 years after their discovery is presented. The great majority of the research was devoted to classification and differentiation of these prokaryotes by molecular and bioinformatic tools applied to specific phytoplasma genes. The availability of a robust classification system has greatly facilitated phytoplasma identification leading to an increased knowledge of plant diseases worldwide. Scientific knowledge on phytoplasma biology still needs to be improved to allow better management solutions to reduce the impact of these diseases in agricultural and natural environments

Phytoplasma Diseases in Ornamental Crops

An extensive and update review of the literature reporting the phytoplasma associated diseases in a number of ornamental plants and their classification is presented with major emphasis to reports in the main floricultural areas. Symptomatology of reported diseases is described in the most relevant traditional species as well as in emerging species used in floriculture and gardening worldwide
