Infection of tobacco mesophyll protoplasts by tobacco mosaic virus.
It was proved that the protoplasts prepared from mesophyll of Nicotiana tabacum are infected by tobacco mosaic virus. The infection occurred when purified tobacco mosaic virus particles were added to a protoplast suspension in the presence of poly-L-ornithine. The virus multiplied in these protoplasts to a level of 10(6) virus particles per infected protoplast during 24 hours of incubation. The...
متن کاملInfection of tobacco mesophyll protoplasts by cucumber mosaic virus.
Protoplasts isolated from tobacco leaves were inoculated with cucumber mosaic virus (CMV) using a method slightly modified from that developed for inoculating tobacco mosaic virus. Multiplication of CMV was demonstrated by staining the protoplasm with fluorescent CMV-antibody, by the electron microscopy of ultrathin sections, and by assaying the infectivity in protoplasts. Seventy to 90% of pro...
متن کاملThe Effects of Salicylic Acid and Tobacco Mosaic Virus Infection on the Alternative Oxidase of Tobacco.
Salicylic acid (SA) is a signal in systemic acquired resistance and an inducer of the alternative oxidase protein in tobacco (Nicotiana tabacum cv Xanthi nc) cell suspensions and during thermogenesis in aroid spadices. The effects of SA on the levels of alternative oxidase protein and the pathogenesis-related 1a mRNA (a marker for systemic acquired resistance), and on the partitioning of electr...
متن کاملA simplified method of obtaining tobacco protoplasts for infection with tobacco mosaic virus.
Incubating tobacco leaf tissue, from which the lower epidermis was peeled, overnight with o'3 to o.4 % Macerozyme and o-6 to i-2 % cellulase, depending on leaf condition, produced a good yield of protoplasts that were susceptible to infection by TMV. Fluorescent antibody staining showed that 20 to 8o % ofprotoplasts became infected, and infectivity tests indicated that an average of about 4 × I...
متن کاملStudy on Genetic Diversity of Terminal Fragment Sequence of Isolated Persian Tobacco Mosaic Virus
Tobacco mosaic virus (TMV) is one of the devastating plant viruses in the world that infects more than 200 plant species. Movement protein plays a supportive role in the movement of other plant viruses, and viral coat protein is highly expressed in infected plants and affects replication and movements of TMV. In order to investigate genetic variation in the terminal fragment sequence in Iranian...
