Embodiments of the present disclosure relate to an isolated peptide consisting of a sequence of 3 to 39 amino acids derived from the amino acid sequence SEQ ID NO: 1, said peptide having a sequence of amino acids selected from the group consisting of: a) sequences of 3 to 39 amino acids comprising at least the residues 6 to 8 of SEQ ID NO: 1, and b) sequences of 3 to 39 amino acids having at least 70% identity with said sequence in a).

A peptide comprised of either a binary or a tertiary peptide, the peptide contains at least 4 amino acids and up to a maximum of 16 amino acids, comprised of 2 or 3 different regions, wherein the binary peptides have 2 different regions and the tertiary peptides have 3 different regions; wherein, the peptide can be cleaved by both an animal gut protease and an insect or nematode gut protease.

Provided are a novel polypeptide, a fusion polypeptide comprising the polypeptide, and a use thereof as an antibiotic. More specifically, provided are a novel polypeptide derived from a bacteriophage, a novel fusion polypeptide comprising cecropin A, and an antibiotic against Gram-negative bacteria comprising the polypeptide and/or the fusion polypeptide.

A method of making sterile diploid organisms includes mating a first population and a second population of single knock-in diploid organisms, wherein the first population of single knock-in diploid organisms are heterozygous organisms expressing a first marker inserted into a gene required for fertility, wherein the second population of single knock-in diploid organisms are heterozygous organisms expressing a second marker inserted into the gene required for fertility, wherein introduction of the first/second marker disrupts expression of the required fertility gene creating a first/second mutant allele of the gene required for fertility, and wherein the first and second markers are distinct; sorting offspring produced from the mating based on their expression of the first and/or second markers; and isolating the sterile diploid organisms, wherein the sterile diploid organisms are heteroallelic diploid organisms expressing the first marker in the first mutant allele and the second marker in the mutant second allele.

Systems, compositions, and methods for target site-specific insertion of a transgene of interest to a subject genome are provided. Systems and methods that facilitate primed reverse transcription (TPRT) mediated by retroelement derived reverse transcriptase (RTs) site-specific transgene insertion are also provided.

The present disclosure relates to a self-assembled nanostructure of an elastin- and resilin-based block copolypeptide with stimuli responsiveness and resilience for drug delivery, tissue engineering and regenerative medicine, a method for preparing the same and application thereof. The diblock polypeptide reversibly forms a self-assembled micelle structure in response to temperature stimuli and a hydrogel prepared using the triblock polypeptide undergoes reversible sol-gel or gel-sol transition in response to temperature stimuli and exhibits enhanced mechanical strength due to chemical crosslinkages between tyrosine residues. With such superior properties, the diblock/triblock polypeptide of the present disclosure can be used for drug delivery systems, scaffolds for tissue engineering and kits for tissue or organ regeneration.

The β-glucan-binding protein contains an amino acid sequence represented by SEQ ID NO: 1.

The present invention relates to control of pest infestation by inhibiting one or more biological functions. The invention provides methods and compositions for such control, By feeding one or more recombinant double stranded RNA molecules provided by the invention to the pest, a reduction in pest infestation is obtained through suppression of gene expression. The invention is also directed to methods for making transgenic plants that express the double stranded RNA molecules, and to particular combinations of transgenic pesticidal agents for use in protecting plants from pest infestation.

The invention provides Cockroach proteins, peptides, subsequences, portions, homologues, variants and derivatives thereof, and methods and uses and medicaments of such proteins, peptides, subsequences, portions, homologues, variants and derivatives thereof. Such methods, uses and medicaments include modulating an immune response, protecting a subject against or treating a subject for an allergic response, allergic disorder or allergic disease and inducing immunological tolerance to the allergen (e.g., Cockroach allergen) in a subject.

The invention relates to identification and characterization of recombinant DNA and polypeptides for specific Bt toxin receptors. In particular, the Bi toxin receptors of the invention include those derived from the Lepidopteran super family including the species Trichoplusiani ni, Pseudoplusia includens, Helicoverpa zea, and Spodoptera frugiperda. The receptors of the invention further include those derived from the Coleopteran super family and particularly from the species Diabrotica virgifera virgifera. The recombinant DNA and polypeptides so provided are useful in the identification and design of novel Bt toxin receptor ligands including novel or improved insecticidal toxins for use in a variety of agricultural applications. Materials and methods for identifying novel toxins are also disclosed herein. The invention also provides methods for selecting toxins to combine to control insect populations by manipulating Bt toxin receptor.
