Filamentous flexous particles and serologically related proteins of variable size associated with citrus psorosis and ringspot diseases
European Journal of Plant Pathology 101 (3), 343-348
Abstract: Filamentous flexous partic les of unusual morphology, previously associated with several ringspot isolates, were detected also in psorosis A and psorosis B isolates by serologically specific electron microscopy using an antiserum to citrus ringspot. Upon partial purification of six ringspot, six psorosis A, and three psorosis B isolates, a specific protein of 47 kDa was detected in most cases, but two isolates (one psorosis A and one ringspot) had a 46 and a 48 kDa-protein, respectively. These differences in molecular masses were observed when purification was done from different host species or from plants co-inoculated with two isolates differing by their protein size. The three types of protein were serologically related in Western blots. Our results indicate that a common virus with different strains may be involved in psorosis A, psorosis B, and ringspot diseases.
