Remission of Aster Yellows Disease by Antibiotics

Science, 1968
Suppression of symptoms of aster yellows by antibiotics supports the tentative hypothesis that the etiologic agent is a mycoplasma- or bedsonia-like organism rather than a virus. Development of symptoms was suppressed by chlortetracycline, tetracycline, or chloramphenicol, but not by penicillin.

Monoclonal Antibodies Against the Aster Yellows Agent

Science, 1985
Hybridoma clones secreting specific monoclonal antibodies against the aster yellows agent, a mycoplasma-like organism, were produced by using partially purified salivary gland preparations from infected leafhopper vectors as the immunogen. After 3947 hybridomas from 20 independent fusions were screened for specific antibody against the aster yellows ...

Influence of Aster Yellows Phytoplasma on the Fitness of Aster Leafhopper (Homoptera: Cicadellidae)

Annals of the Entomological Society of America, 2000
This study revealed that feral aster leafhoppers, Macrosteles quadrilineatus Forbes, exposed to aster yellows phytoplasma live longer and may lay more eggs than nonexposed leafhoppers. Aster leafhoppers were reared on asters infected with either of 2 strains of aster yellows phytoplasma or uninfected asters.
