Sweet potato has been identified as a crop that has great potential for alleviating food security concerns (28). However, because it is vegetatively propagated, it is prone to accumulate viruses and other pathogens. Sweet potato viruses are difficult to transmit mechanically, they occur in mixed infections, and their host range often is restricted to the family Convolvulaceae (24). These factor...

abstractbackground and objectives: the cultivated tobacco (nicotiana tabacum) is a tropical and annual plant, consisting of a number of species or hybrids belonging to the solanaceae family. bio-chemical reaction to viral infection is different for various plants .one of the most important defensive mechanisms of the host plant against pathogen agents, is biochemical defense and their related c...

Snap bean (Phaseolus vulgaris L.) is a major crop in the Great Lakes region of the United States. The most significant production occurs in Wisconsin, Michigan, New York, Illinois, and Pennsylvania. Snap bean crops also are produced in the Pacific Northwest, Georgia, Florida, and Ontario, Canada. In 2005, 124,367 ha of snap bean were harvested with a farm gate value of approximately $400 millio...

In 1949, Jensen reported that the first papaya disease attributed to a virus was described in the Caribbean (14). According to Jensen, the virus, presumably Papaya ringspot virus (PRSV), was recorded by Smith in 1929 and was considered the primary reason for no large-scale cultivation of papaya (Carica papaya L.) in Jamaica. However, in the mid-1980s, papaya (also locally known as pawpaw) was p...
