Abstract: A novel transgenic wheat event designated JOPLIN1, is disclosed. The invention relates to DNA sequences of the recombinant constructs inserted into the wheat genome and of genomic sequences flanking the insertion site that resulted in the JOPLIN1 event.

Abstract: A hybrid yeast promoter comprising constituents of the 5' non-coding PGK region and, as an upstream activation sequence, the upstream activitation sequence of the GAL10 gene of Saccharomyces cerevisiae, and which does not contain the endogenous PGK upstream activation sequence. Preferably the GAL10 upstream activation sequence is provided at a site from which the PGK upstream activation sequence has been deleted. The hybrid promoter confers galactose regulation of gene transcription.

Abstract: A 2 .mu.m plasmid vector for transforming yeast, especially brewing yeast, much which comprises a DNA sequence allowing propagation of the plasmid in bacteria, two copies of the 74 base pair FLP recombination site of the 2 .mu.m plasmid in direct orientation and a DNA sequence coding for a protein or peptide of interest. The plasmid is so constructed that in yeast the bacterial DNA sequence is between the two recombination sites which are in direct orientation and is spontaneously lost following recombination. A "gene of interest" is preferable inserted at the SnaBI site.

Abstract: Polypeptides corresponding to mature human serum albumin residues 1 to n, where n is between 369 and 419 inclusive, are useful as substitutes for albumin in the treatment of burns and shock in humans, the clearance of undesirable compounds, (such as bilirubin) from human blood, in laboratory growth media and in HSA assays. The polypeptides may be produced by recombinant DNA techniques, especially in yeast.

Abstract: Yeast is genetically modified by transformation with an integration vector comprising two copies of a homologous 2 .mu.m plasmid DNA sequence in direct orientation relative to one another and encompassing the said DNA sequence, and then isolating, from the transformed yeast obtained, cells containing the endogenous 2 .mu.m plasmid modified by incorporation of the said DNA sequence but not containing the said vector. The resulting yeast can be maintained under non-selective growth conditions.
