Virus assembly, utilizing a limited number of viral coat protein (CP or VP) building blocks, is an excellent example of a directed macromolecular interaction occurring in nature. Two basic principles govern the assembly of spherical (icosahedral) viruses: (i) Genetic Economy – the encapsidated genome encodes a single or few CPs that assemble a protective shell (the viral capsid); and (ii) speci...

Viral diseases occur wherever sweet potato (Ipomoea batatas) is cultivated and because this crop is vegetatively propagated, accumulation and perpetuation of viruses can become a major constraint for production. Up to 90% reductions in yield have been reported in association with viral infections. About 20 officially accepted or tentative virus species have been found in sweet potato and other ...

Understanding the structure and dynamics of microbial communities, especially those of economic concern, is of paramount importance to maintaining healthy and efficient microbial communities at agricultural sites and large industrial cultures, including bioprocessors. Wastewater treatment plants are large bioprocessors which receive water from multiple sources, becoming reservoirs for the colle...

turnip curly top virus (tctv) is a member of the newly established genus turncurtovirus, family geminiviridae. development of an efficient detection system is necessary to study the biological characteristics of viruses. due to the superior efficacy of the serological methods for detection of plant viruses, in this research, with the aim to facilitate the process of immunological detection of t...

Implementation of a vector-enabled metagenomics approach resulted in the identification of various geminiviruses. We identified the genome sequences of Beet curly top Iran virus, Turnip curly top viruses, Oat dwarf viruses, the first from Iran, and Wheat dwarf virus from leafhoppers feeding on beet, parsley, pumpkin, and turnip plants.
