متن کاملReduced levels of chloroplast FtsH protein in tobacco mosaic virus-infected tobacco leaves accelerate the hypersensitive reaction.
In tobacco cultivars resistant to tobacco mosaic virus (TMV), infection results in the death of the infected cells accompanying the formation of necrotic lesions. To identify the genes involved in this hypersensitive reaction, we isolated the cDNA of tobacco DS9, the transcript of which decreases before the appearance of necrotic lesions. The DS9 gene encodes a chloroplastic homolog of bacteria...
متن کاملPathological Cytology of Tobacco Leaf Infected with Tobacco Mosaic Virus III
The idea that chloroplasts are the sites of virus formation is not new. Since Kausche and Ruska (4) published an electron micrograph showing filamentous particles of tobacco mosaic virus associated with chloroplast fragments, the speculation that virus particles are formed within chloroplasts and released from them into the surrounding cytoplasm, has been widely supported by successive investig...
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...
