Methods and compositions are provided for durably influencing microbiological ecosystems (microbiomes) in a subject in order to prevent infection and reduce recurrence of infection by microorganisms. In some embodiments, compositions and methods are provided for the creation and use of molecularly-modified bacterial strains with the potential to prevent a variety of microorganism infections.

The invention in some aspects relates to isolated nucleic acids, compositions, and kits useful for identifying adeno-associated viruses in cells. In some aspects, the invention provides kits and methods for producing somatic transgenic animal models using recombinant AAV (rAAV) to an animal having at least one transgene that expresses a small interfering nucleic acid or at least one binding site for a miRNA.

The invention describes chimeric Flavivirus constructs comprising lyssavirus G proteins in the E/NS1 intergenic region.

Provided herein are recombinant virus systems comprising two or more coordinatedly regulated viral vectors. Methods for treating a cell proliferative disorder using these systems are also provided. The compositions and methods provided herein provide more efficient and coordinated delivery of larger transgenes and/or larger quantities of a tansgene than previous methods by avoiding receptor interference and/or superinfection resistance, thereby enabling progressive replication of both vectors and efficient gene delivery by each vector.

Two novel cytochrome P450 genes are isolated from sorghum, each gene encoding a protein having pentadecatrienyl resorcinol hydroxylase activity. Expression vectors containing these sequences are made and used to elevate levels of pentadecatrienyl resorcinol hydroxylase in transgenic cells and organisms.

The present disclosure provides plants that express a variant phosphoenolpyruvate carboxylase (PEPC) enzyme. The plants have enhanced resistance to aluminum than comparable plants that lack the variant PEPC enzyme. In addition, the plants more effectively sequester carbon, extract phosphate, and produce oxaloacetate-derived amino acids and glucose than comparable plants that lack the variant PEPC enzyme. The disclosure also provides tools for production of plants that express the variant PEPC enzyme.

Fungal artificial chromosome (FAC) vectors are disclosed. A vector can be replicated in a bacterial or a fungal host, and can comprise an insert of heterologous DNA up to about 500 kilobases. A vector can be used for cloning and expressing a secondary metabolite (SM) gene cluster. An insert sequence can be modified by homologous recombination. A vector can be a plasmid comprising bacterial and fungal origins of replication, as well as bacterial and fungal selection marker genes. Also disclosed are vectors that can be integrated into a fungal genome, and dual function vectors which can be replicated in a bacterial or a fungal host and can also be integrated into a fungal genome. Also disclosed are methods of generating plasmid libraries including vectors comprising intact SM gene clusters.
