Sensitivity of Tobacco Mosaic Virus to Ultraviolet Irradiation

The Ultraviolet Light and Photosensitized Inactivation of Tobacco Mosaic Virus

The quantum yield for the inactivation of tobacco mosaic virus has been determined at 253.7 mmicro and found to be 4.3 x 10(-6). The possible significance of the observed one-hit process of inactivation has been discussed in terms of the kinetics and the rupture of model substances including nucleic acid. The ultraviolet light inactivation, which proceeds independent of oxygen, occurs without c...

Quantum yields for inactivation of tobacco mosaic virus nucleic acid by ultraviolet radiation (254 nm.).

The quantum yield, under non-photoreactivating conditions, for inactivation of tobacco mosaic virus RNA by ultraviolet radiation (254 nm.) is independent of the RNA concentration but varies appreciably with the ionic strength of the irradiation solvent, being approximately three times greater in water than in o-I M-potassium phosphate buffer. Photoreactivation of inactivated tobacco mosaic viru...

Study 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...

Dielectric spectroscopy of Tobacco Mosaic Virus.

The dielectric properties of the Tobacco Mosaic Virus (TMV) have been measured using time domain dielectric spectroscopy (TDDS) in the temperature range from 1 to 40 degrees C. A single dielectric dispersion is observed in the MHz range. The activation energy of the process is found to be in the range 1-2 kcal/mol. The experimental data could not be completely accounted for by current theoretic...
