Abstract: A transferrable maize gene is disclosed which is a dominant mutant allele at the amylose-extender (ae) locus. Maize seeds having this gene produce a high-amylose starch.

Abstract: A method is disclosed for the production of esters by reaction of an allylic ether with carbon monoxide in the presence of a catalytically effective amount of a Group VIII noble metal catalyst and a Group IB metal halide to obtain esters. The Group IB metal halide is present in an amount sufficient to prevent the catalyst from being converted into a Group VIII metal during the reaction. When the reaction is conducted in the presence of a quaternary ammonium salt the ester may be extracted by solvent extraction to minimize catalyst decomposition caused when extractive distillation is used to separate the ester.

Abstract: A method is disclosed to achieve genetic transformation of cotton plants and lines. Immature cotton tissues are genetically transformed in vitro, by Agrobacterium-mediated genetic transformation. The resultant cotton tissues are subjected to a selection agent or agents to screen for transformants. The transformed cultures are then induced to commence somatic embryogenesis. One possible regime for regenerating such somatic embryos into whole cotton plants is disclosed.

Abstract: Novel benzoic acid or benzoic acid ester derivatives, pharmaceutical compositions and methods of use thereof are the present invention. Utility is for the treatment of arthritis, asthma, Raynaud's disease, inflammatory bowel disorders, trigeminal or herpetic neuralgia, inflammatory eye disorders, psoriasis, dental pain, and headaches, particularly vascular headache, such as migraine, cluster, mixed vascular syndromes, as well as nonvascular, tension headaches.

Abstract: A process for producing a physiologically active substance by a combined enzymatic method is disclosed.

Abstract: DNA sequence elements which effect anaerobic induction of genes in plants are identified and characterized. These sequence elements, designated anaerobic regulatory elements, confer inducibility by anaerobic conditions on downstress plant-expressible promoters and their associated structural genes. In particular, those sequences associated with anaerobic induction of the maize alcohol dehydrogenase and aldolase genes have been identified. These sequence elements can be employed in combination with appropriately positioned plant-expressible genes to produce chimeric, anaerobically inducible genes. Such constructs are useful for the selective expression of structural genes under anaerobic conditions in plants.

Abstract: This invention relates to a process for producing ring alkylated aromatic amines where the alkyl substituent is ortho to the amino group by reacting an N-alkylated aromatic amine with a C.sub.2-10 olefin in the presence of a solid phase acidic catalyst, e.g., silica-alumina or a zeolite. High conversion and selectivity is achieved by maintaining a mole ratio of olefin to amine of from about 1-10:1 and an operating pressure of at least 50 psig.

Abstract: Maize cDNA coding for nitrite reductase is cloned, using a spinach nitrite reductase cDNA as a heterologous probe, and is characterized. A method is provided to use the cloned maize nitrite reductase cDNA to determine the number of nitrite reductase genes per maize genome and to study nitrite reductase mRNA regulation in maize.

Abstract: Phosphatides are shown to have antiviral activity, where the phosphatides are characterized by having a polyunsaturated fatty acid at the sn2 position. By contacting cells susceptible to or infected with a virus, particularly a retrovirus, the proliferation of the virus is substantially inhibited.

Abstract: The invention relates to live deletion mutants of a herpesvirus, especially of Pseudorabies virus. The genomes of the mutants differ from the genomes of the parent strain by the presence of one or more deletions selected from a deletion in the inverted repeats, a deletion in the unique sequence, and a deletion in the thymidine kinase gene.The new deletion mutants are avirulent, do not induce latent infections, are stable and possess good immunogenic properties.The invention also relates to vaccines containing the new mutant strains.
