Mycoplasmalike Organisms in Sieve Tube Elements of Plants Infected with Blueberry Stunt and Cranberry False Blossom. Tseh An Chen, Associate Professor, Department of Entomology and Economic Zoology, Rutgers University, New Brunswick, New Jersey 08903; Phytopathology 61:233-236. Accepted for publication 23 September 1970. DOI: 10.1094/Phyto-61-233.

Leaf tissues of plants infected with blueberry stunt and false blossom of cranberry were examined with the electron microscope. Mycoplasmalike organisms were found in the sieve tube elements, but were absent in the control healthy plants. These bodies ranged in diameter from 80-300 nanometers (nm) for cranberry false blossom and 160-700 nm for blueberry stunt. The constant association of these microorganisms with the diseased plants suggested the possible roles they play in the etiology of the two diseases.
