CHENOPODIUM QUINOA WILLD. AS AN INDICATOR PLANT FOR CARNATION LATENT VIRUS

Cole latent virus (CoLV), genus Carlavirus, was studied by electron microscopy and biochemical approaches with respect both to the ultrastructure of the Chenopodium quinoa infected cells and to its association with chloroplasts. The CoLV was observed to be present as scattered particles interspersed with membranous vesicles and ribosomes or as dense masses of virus particles. These virus particles reacted by immunolabelling with a polyclonal antibody to CoLV. Morphologically, chloroplasts, mitochondria and nuclei appeared to be unaltered by virus infection and virus particles were not detected in these organelles. However, virus particle aggregates were frequently associated with the outer membrane of chloroplasts and occasionally with peroxisomes. Chloroplasts were purified by Percoll gradient, and the coat protein and virus-associated RNAs were extracted and analyzed by Western and Northern blots respectively. Coat protein and CoLV-associated RNAs were not detected within this organelle. The results presented in this work indicate that the association CoLV/chloroplasts, observed in the ultrastructural studies, might be a casual event in the host cell, and that the virus does not replicate inside the organelle.

Carnation Latent Virus

The position (p) of precipitin bands in OUCHTERLONY’S test with tobacco mosaic virus and carnation latent virus depends upon the concentration of agar and electrolyte. This dependence results from the greater diffusional restriction of antigen in comparison to that of antibody. It is suggested that the effect of electrolyte concentration on the antigen in gel is mechanistically the same as the interaction between virus and agar in the sol state. Antisera against seven distantly related viruses of the potato virus S group reacted with carnation latent, potato M, and red clover vein mosaic viruses. This further demonstrates a serological relationship between viruses of the same shape but different normal length.
