Myooplasma-Like Bodies in French Bean, Dodder, and the Leafhopper Vector of the Legume Little Leaf Agent

Abstract

Mycoplasma.like bodies were observed in the phloem sieve tube elements of French bean (Phaseolus vulgaris L.) and dodder (Guscuta australis R.Br.) carrying the legume little leaf disease agent. In dodder they occurred in small groups of approximately 5-30, in contrast to the very large numbers in bean. In bean, some of the bodies were located within the sieve plate pores
