Electron Microscopical Investigations on Tristeza

Abstract: CITRUS VIRUSES have b~e n the subject of an increasing number of publications during recent years. So far as the writers know, however, there is no mention of electron microscopically detectable particles representing these viruses, with the exception perhaps of the report that psorosis virus is spherical ( 10) .Electron microscopical studies on tristeza have been carried out in the Virus Department of the Instituto Agronomic0 de Campinas for more than two years. This paper reports the finding of a thread-like… Show more

“…CTV is a member of the Closteroviridae family of the genus Closterovirus. The virus consists of a single, positive-stranded RNA genome enveloped in a helical-shaped, long, flexuous protein particle measuring approximately 11 × 2,000 nm in size (Kitajima, Silva, Oliveira, Müller, & Costa, 1964;Bar-Joseph et al, 1989;Muniz et al, 2012). Citrus is a graft-propagated perennial crop, and CTV is readily graft-transmissible.…”

“…The first citrus disease shown to be caused by a virus was psorosis in 1933 (32). About 20 virus and viruslike diseases of citrus are recognized now (53,55,56); to cite an exact number is difficult because, like taxonomists, citrus virolo gists disagree on which diseases should be lumped together and which should be considered separately. Recent summaries of citrus virus research have been published (7,54,55,56,80,89,126).…”

“…El análisis, por microscopía electrónica, de savia de distintas especies de cítricos infectadas permitió observar la presencia de partículas con forma de hilo, de unos 10 a 12 nm x 2000 nm, que no se encontraron en preparados de árboles sanos (Kitajima et al, 1965; Bar-Joseph et al, 1970a) (fig. I.2).…”
