Sap extracted from virus-infected plants reacted positive with an antiserum prepared against Tobacco mosaic virus TMV using an antigen-coated plate enzyme-linked immunosorbent assay.

The CP gene was amplified by reverse transcription-polymerase chain reaction with primers specific to Tomato mosaic virus ToMV and sequence data obtained from the resulting amplification product.

AY shared On the basis of biology, serology, properties of virions, and the sequence of the CP gene, we conclude that the virus isolated from H. References: 1 S. Adkins et al. Plant Dis. The symptoms vary from tiles, wrinkle, reduction and curvature of leaflets, and irregular ripening of fruits. This disease requires attention because of its easy dissemination by contact, cultural practices, or contaminated seed. ToMV has a rod shaped structure, about nm length and 18 nm radius.

ToMV has its genetic material enclosed in a protein coat. The two proteins involved in replication are encoded by the genomic RNA where as the two involved in virus packaging and movement are translated by sub-genomic RNAs.

The virus particles are very stable and remain infectious for many years after extraction. Tomato mosaic virus symptoms can be found at any stage of growth and all parts of the plant may be infected. ToMV causes yellow mosaic symptoms on the leaves and tomato fruits. Tomato mosaic virus symptoms are seen as a general mottling or mosaic appearance on foliage.
