Abstract:
Begomoviruses (family Geminiviridae) cause important diseases in many crops. In addition, many wild plants are reservoirs of begomoviruses, which are a potential menace for nearby crops. A novel begomovirus was isolated from a weed of the species Synedrella nodiflora (Compositae) exhibiting yellow vein symptoms in South India. This virus had a typical monopartite Old World begomovirus genome and was accompanied by a betasatellite. Sequence comparison revealed that this virus represents a new species in the genus Begomovirus. Recombination analysis showed that the novel begomovirus originated through recombination between the begomoviruses ageratum yellow vein Sri Lanka virus and tomato leaf curl Sri Lanka virus.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
