Abstract In New Zealand, alfalfa mosaic virus is recorded on three new field crop hosts, Cajanus cajan (L.) Huth, Coriandrum sativum L., and Wasabia japonica (Miquel) Matsum. Cucumber mosaic virus is recorded on the weeds Cirsium vulgare L. and Veronica persica Poiret and on the ornamental perennial Gentiana sp.

The anatomy of the tobacco mosaic virus
Virology, 1964Abstract Novel electron microscopical techniques have been applied to an analysis of the structure of the tobacco mosaic virus. A photographic linear integrating apparatus used in conjunction with the 11.94 A crystal lattice of platinum phthalocyanine permits both the visualisation of structures obscured by “noise” and also very precise measurement ...

Publisher Summary This chapter discusses the work on all aspects of the turnip yellow mosaic virus (TYMV). TYMV, which can be obtained in good yield from infected plants, and which has a high content (about 34%) of RNA, provided a valuable source of RNA for work establishing the structure of natural RNA and the mechanisms of enzymic degradation of ...

The replication of cowpea mosaic virus
BioEssays, 1986AbstractCowpea mosaic virus (CPMV) is the type member of the comovirus group, which contains 14 different plant viruses that have the same structural organization of genomic RNAs and virions and use the same mechanism for expression of the viral RNAs. The combined structure and organization of the two CPMV genomic RNAs is strikingly similar to that of ...

, 1986 Tomato mosaic virus (ToMV), which has occurred in tomato (Lycopersicon esculentum) in the United States (Clinton, 1909; Allard, 1916) and the Netherlands (Westerdijk, 1910) for over 75 years, now probably occurs wherever tomato crops are grown (Broadbent, 1976; Hollings and Huttinga, 1976).

Resistance to Tobacco Mosaic Virus and Tomato Mosaic Virus in Tomato
2007Tobacco mosaic virus (TMV) and Tomato mosaic virus (ToMV) cause a serious disease in tomato, with systemic mosaic symptoms and losses in fruit yield and quality. Both viruses are closely related tobamoviruses, plus stranded RNA viruses with a rod like particle structure.

Crystalline cowpea mosaic virus
Virology, 1980Crystals of Cowpea mosaic virus displaying a high degree of order have been grown in two different forms. Hexagonal crystals, space group P6(1)22 or P6(5)22 with a = 450 A and c = 1038 A containing six virus particles per cell, have been grown in sodium citrate buffer at pH 4.9. Each particle has four nearest neighbors at 284 A.

SUMMARYNarcissus mosaic virus (NMV) is widespread in British crops of trumpet, large‐cupped and double daffodils, but was not found in Narcissus jonquilla or N. tazzeta. Many commercial daffodil cultivars seem totally infected, and roguing or selection is therefore impracticable.

The morphology of arabis mosaic virus
Journal of Ultrastructure Research, 1967Preparations of arabis mosaic virus were examined by electron microscopy, using the negative staining method. Good agreement was found between the micrographs and an icosahedral model with 42 capsomeres having 5:3:2 symmetry. Thus, the protein shell of the virus appears to be composed of 42 capsomeres.

Holmes (1941) was the first to recognize that a virus isolated from ribgrass and broad-leaf plantain was distinct from tobacco mosaic virus (TMV). But the history of the virus began earlier because Holmes called the attention of Valleau and Johnson (1943) to a similar virus that these authors had found in Plantago major and which they had transferred ...
