The present disclosure provides an isolated or purified Porcine Epidemic Diarrhea Virus (PEDV) or Porcine Epidemic Diarrhea Virus (PEDV) S1 protein, and methods of use thereof.

The present invention provides a new species of tobamovirus and its use to identify plants comprising resistance against the virus.

Microspheres are produced by contacting a solution of a macromolecule or small molecule in a solvent with an antisolvent and a counterion, and chilling the solution. The microspheres are useful for preparing pharmaceuticals, nutraceuticals, cosmetic products and the like of defined dimensions.

Novel nucleic acids include non-integrative chimeric retroviral genomes including the 5 and 3 long terminal repeat sequences (LTRs) of the caprine lentivirus: the Caprine Arthritis Encephalitis Virus (CAEV) or of another retrovirus not integrating human cells and at least one viral gene of another retrovirus. A vector including such a nucleic acid, an immunogenic or vaccinal composition including the vector or the nucleic acid, as well as their use for treating and/or preventing an infection by a retrovirus or a disease induced by a pathogenic agent are also described.

The present invention provides plant virus vectors developed from the Foxtail mosaic virus (FoMV). The vectors include a nucleic acid sequence encoding an infectious Foxtail mosaic virus (FoMV) with a functional movement encoding sequence operably linked to one or more regulatory elements functional in a plant. The plant virus vectors may be used to infect monocot plants, such as maize and can be used for VIGS, gene editing, gene expression or other transgenic protocols.

The present disclosure provides an isolated or purified Porcine Epidemic Diarrhea Virus (PEDV) or Porcine Epidemic Diarrhea Virus (PEDV) S1 protein, and methods of use thereof.

At least one novel virus capable of infecting crazy ants (Nylanderia fulva) is isolated, along with polynucleotide sequences and amino acid sequences of the virus. The virus is capable of be used as a biopesticide to control populations of crazy ants.

A method for simply constructing a two-component virus vector and related applications. The two-component plant viral vector is optimized, so that a two-component virus genome is placed in a single plasmid. Due to the use of the single plasmid, the activation, resuspension and mixing processes of auxiliary bacteria are avoided, the workload of an Agrobacterium experimental stage is simplified by half, the potential cross-contamination risk in the bacteria mixing process is avoided, and the virus infectivity is improved, so that the use of the two-component viral vector is greatly simplified.
