Lifestyles of plant viruses.
The vast majority of well-characterized eukaryotic viruses are those that cause acute or chronic infections in humans and domestic plants and animals. However, asymptomatic persistent viruses have been described in animals, and are thought to be sources for emerging acute viruses. Although not previously described in these terms, there are also many viruses of plants that maintain a persistent ...
متن کاملMetagenomics of plant and fungal viruses reveals an abundance of persistent lifestyles
INTRODUCTION Most studies of plant viruses have focused on the acute viruses that cause disease in crop and ornamental plants. These viruses are transmitted horizontally, often by insect vectors, and are occasionally transmitted vertically. Although known for at least four decades, the persistent viruses of plants are very poorly studied. These viruses were previously called “cryptic” because t...
متن کاملPlant Viruses and Insects
The principal families of insect vectors which cause the most damage to agricultural crops through the spread of plant diseases are in the order Hemiptera, and include the aphids, leafhoppers, delphacid planthoppers and whiteflies. Another important group of insect vectors found worldwide is the order Thysanoptera, the thrips. Other insects also spread plant diseases; however, aphids alone are ...
متن کاملMolecular Diagnosis of Plant Viruses
Makkouk, K.M. and S.G. Kumari. 2006. Molecular Diagnosis of Plant Viruses. Arab J. Pl. Prot. 24: 135-138. Proper virus identification is always the key in developing appropriate practical solutions to manage plant virus diseases. Recent advances in biotechnology and molecular biology have played a significant role in the development of rapid, specific and sensitive diagnostic tests. The use of ...
متن کاملStability of recombinant plant viruses containing genes of unrelated plant viruses.
The stability of hybrid plant viruses that might arise by recombination in transgenic plants was examined using hybrid viruses derived from the viral expression vectors potato virus X (PVX) and tobacco rattle virus (TRV). The potato virus Y (PVY) NIb and HCPro open reading frames (ORFs) were introduced into PVX to generate PVX-NIb and PVX-HCPro, while the PVY NIb ORF was introduced into a vecto...
