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 کاملResponse of Membrane-bound Mg-activated ATPase of Tobacco Leaves to Tobacco Mosaic Virus.
Infectious material was formed at an early stage, and migrated into the mesophyll from the epidermis of tobacco leaves (Nicotiana tabacum cv. Samsun NN) during the period of 1 to 3 hours after inoculation with tobacco mosaic virus (TMV). The activity of membrane-bound Mg(2+)-activated ATPase from the mesophyll was stimulated two to four times within 30 minutes after inoculation with 1.0 microgr...

متن کاملInduction of UDP-Glucose:Salicylic Acid Glucosyltransferase Activity in Tobacco Mosaic Virus-Inoculated Tobacco (Nicotiana tabacum) Leaves.
Salicylic acid (SA) is a putative signal that activates plant resistance to pathogens. SA levels increase systemically following the hypersensitive response produced by tobacco mosaic virus (TMV) inoculation of tobacco (Nicotiana tabacum L. cv Xanthi-nc) leaves. The SA increase in the inoculated leaf coincided with the appearance of a [beta]-glucosidase-hydrolyzable SA conjugate identified as [...
متن کاملTobacco Mosaic Virus Infection Does Not Alter the Polyadenylated Messenger R N A Content of Tobacco Leaves
Measurements of incorporation of 3H-histidine into proteins in discs from tobacco mosaic virus-infected leaves suggest that the rate of host protein synthesis is reduced by up to 75 % during virus multiplication but then recovers. Polyadenylated messenger RNAs from healthy and virus-infected plants were found to have similar size distributions and polyadenylic acid chains of similar lengths. To...
