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 کاملInteractions between tobacco mosaic virus and the tobacco N gene.
The interaction between tobacco mosaic virus (TMV) and tobacco harbouring the N gene is a classical system for studying gene-for-gene interactions in disease resistance. The N gene confers resistance to TMV by mediating defence responses that function to limit viral replication and movement. We isolated the N gene and determined that N belongs to the nucleotide-binding-site-leucine-rich-repeat ...
متن کاملInfection 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...
