When a cell is infected with a virus several effects may be seen. Many viruses cause no harm or disease whatsoever. However, some viruses may attack certain cells and multiply within them. Plant Disease is the leading international journal for rapid reporting of research on new, emerging, and established plant diseases. The journal publishes papers that describe translational and applied research focusing on practical aspects of disease diagnosis, development, and management in agricultural and horticultural crops.

Elizabeth A. Worrall, Neena Mitter, in Advances in Virus Research, Abstract. The closely related potyviruses Bean common mosaic virus (BCMV) and Bean common mosaic necrosis virus (BCMNV) are major constraints on common bean (Phaseolus vulgaris) losses caused by BCMV and BCMNV impact severely not only on commercial scale cultivation of this high-value crop but also on.
Two viruses, that is, maize dwarf mosaic virus and maize streak virus, have somewhat widespread distribution in many pearl millet growing countries in Africa, Asia and Americas. Other viruses (namely panicum mosaic virus, wheat streak mosaic virus, guinea grass mosaic virus and Indian peanut clump virus) are reported from a few countries.

Abstract. The common bean (Phaseolus vulgaris) is one of the most important food legumes in the world (over 26 million hectares worldwide), particularly in Latin America, its center of origin (Singh et al., ), and East Latin America, Brazil is the main producer of common beans, with approximately million tons, followed Bean common mosaic virus and related viruses in Africa.
book Mexico with million tons, and Central America with. browning, Pea enation mosaic and Soy bean dwarf viruses are important in specif ic locations in specific countries.
Significant prog ress has been made at ICARDA in virus characterization and dia. Since the s, the incidence of Bean golden mosaic virus (BGMV) has made it probably the most devastating viral disease of common beans in these states. The effect of this disease alone may account for the importation needs of the country.
Golden Mosaic of Common Beans (Bean golden mosaic virus). A virus causing severe mosaic symptoms was isolated from cowpea (Vigna sinensis [V. unguiculata]) plants of the cultivars Cream No. 7 and Blackeye growing at Giza, Egypt.
The characteristics of the virus are described. Transmission could occur mechanically, through seeds or by Myzus persicae or Aphis craccivora.
The virus was identified as cowpea aphid-borne mosaic by: 1. Human viruses cause a variety of maladies, depending on the virus type and the tissues infected. All humans contract multiple viruses throughout the course of life.
The severity of viral illnesses ranges from mild to lethal. Cold, flu, stomach and hepatitis viruses are among the most common types of human viruses encountered worldwide. Potyvirus is a genus of viruses in the family serve as natural hosts.
There are currently species in this genus including the type species Potato virus Y. The genus is named after the type virus (potato virus Y).Potyviruses account for ~30% of the currently known plant : Potyviridae. Abstract. In this chapter, the designation tobacco mild green mosaic virus (TMGMV) is used for an ensemble of serologically closely related viruses (Table I) containing among others the well-characterized U2 strain (Siegel and Wildman, ; Wetter, a,b).Cited by: The subject of her PhD was Bean Common Mosaic Virus in Phaseolus beans in Africa.

With work encompassing ecology, physiology and behavioural aspects, his main strategy has been to develop environmentally friendly methods of pest management. and has worked. Plant viruses recruit cellular translation factors not only to translate their viral RNAs but also to regulate their replication and potentiate their local and systemic movement.
Because of the virus dependence on cellular translation factors, it is perhaps not surprising that many natural plant recessive resistance genes have been mapped to mutations of translation initiation factors eIF4E Cited by: new plague of this century, and West Nile virus, a virus similar to yellow fever virus in being transmitted by mosquito but appearing for the ﬁrst time in North America, in New York City during the late s.

The virus was first reported in Sudan in the s, where it has been a threat for several decades. Then, init was found in Tanzania.
To date, TYLCV is widespread in many countries of the subregion. It is not well known whether TYLCV has occurred in these countries from some time ago, as in Sudan. Diseases and insect pests are the major constraints to production in Kenya and most cultivars grown by farmers are susceptible.
The major diseases and percentage crop losses are: halo blight (Pseudomonas syringae pv. phaseolicola; %), anthracnose (Colletotrichum lindemuthianum; %), angular leaf spot (Phaeoisariopsis griseola; %), common bacterial blight (Xanthomonas campestris Cited by: 1.
