Abstract: Genes encoding a glyphosate oxidoreductase enzyme are disclosed. The genes are useful in producing transformed bacteria and plants which degrade glyphosate herbicide as well as crop plants which are tolerant to glyphosate herbicide.

Abstract: A cDNA clone from barley, pAGL.2737, SEQ ID NO: 3, which encodes the enzyme .alpha.-glucosidase, is disclosed. A vector and microbial host containing a DNA sequence coding for the expression of barley .alpha.-glucosidase, and a DNA construct comprising a DNA sequence coding for the expression of barley .alpha.-glucosidase, together with a promoter located 5' to the DNA coding sequence and a 3' termination sequence, are also disclosed.

Abstract: An overall process for the preparation and recovery of 7-aminodesacetoxycephalosporanic acid (7-ADCA) via enzymatic ring expansion activity on penicillin G, using a Penicillium chrysogenum transformant strain expressing expandase.

Abstract: Hybrid regulatory proteins are provided which contain amino acid sequences that are susceptible to cleavage by specific proteolytic enzymes. When acted upon by such enzymes, the hybrid regulatory proteins are rendered substantially less active, thereby altering the rate of production of products of indicator genes that are controlled by the regulatory proteins. Also provided are DNAs encoding such regulatory proteins, recombinant vectors and transformed eukaryotic cells containing such DNAs, and methods for identifying inhibitors of the specific proteolytic enzymes.

Abstract: Recombinant DNA replicable in microorganisms belonging to the genus Corynebacterium, which contains a DNA fragment coding for an aspartokinase .alpha.-subunit protein originating from a bacterium belonging to the genus Corynebacterium, in which synergistic feedback inhibition by L-lysine and L-threonine is substantially desensitized, and a DNA fragment coding for an aspartokinase .beta.-subunit protein originating from a bacterium belonging to the genus Corynebacterium, in which synergistic feedback inhibition by L-lysine and L-threonine is substantially desensitized, is introduced into a microorganism belonging to the genus Corynebacterium. Thus a transformant having enhanced production and excretion speeds of L-lysine is obtained. The transformant is cultivated in an appropriate medium, and produced L-lysine is separated.

Abstract: The present invention relates to a newly isolated Bacillus thuringiensis strain which exhibits insecticidal activity. The supernatant of cultures of this novel strain is also an effective insecticidal agents. Also included in the invention are the novel B. thuringiensis isolate, its supernatant and a solvent extract of the supernatant which are specifically active against corn rootworm but not against beet armyworm, nematodes or flies. These strains and supernatants may be used to treat plants infected with susceptible organisms.
