PATENT ABSTRACTS endonuclease by (1) introducing the restriction endonuclease gene from E. agglomerans ATCC into a host whereby the restriction gene is expressed; (2) fermenting the host which contains the vector encoding and expressing the Eag I restriction endonuclease, and (3) purifying the Eag I restriction endonuclease from the fermented host which contains the vector encoding and expressing the Eag I restriction endonuelease activity.

4996152 AVIAN HERPESVIRUS AMPLICON AS A EUCARYOTIC EXPRESSION VECTOR Jeanne Carter, Robert Silva assigned to The United States of America as represented by the Secretary of Agriculture DNA fragments (seeds) having the characteristics of amplicons, which are useful for amplifying genes of interest, have been isolated from Marek's disease viruses of poultry. Concatmers of the seeds and the associated genes have potential as vaccines or delivery vectors when cotransfected and replicated in the presence of helper viruses. The amplicons are also useful for inserting associated genes into the helper viruses, which in turn could be used as expression vectors. Candidate genes for use with the subject amplicons include those which encode immunogenic proteins and other beneficial economic traits desired in commercial poultry lines.

4996155 BACILLUS THURINGIENSIS GENE ENCODING A COLEOPTERAN-ACTIVE TOXIN August Sick, Thomas E Gilroy assigned to Mycogen Corporation A novel B.t. toxin gene encoding a protein toxic to coleopteran insects has been cloned from a novel coleopteran-active B. thuringiensis microbe. The DNA encoding the B.t. toxin can

be used to transform various prokaryotic and eukaryotic microbes to express the B.t. toxin. These recombinant microbes can be used to control coleopteran insects in various environments.

4996156 PREPARATION OF SPORE-FREE, CONCENTRATED PROTEIN PREPARATIONS FROM BACILLUS THURINGIENSIS SEROVAR, ISRAELENSIS, WHICH IS TOXIC FOR GNATS, A MICROORGANISM FOR THEIR PREPARATION, AND THE ISOLATION OF THE MICROORGANISM Han Zaehner, Konrad Bernhard, Harald Weisser, 7400 Tuebingen, Federal Republic Of Germany Asporous mutants of Bacillus thuringiensis serovar, israelensis, a process for their preparation and their use for the isolation of bacterial toxins for controlling diptera.

4996390 NOVEL INTERSPECIFIC MUSHROOM STRAINS Kurt R Dahlberg assigned to Campbell Soup Company This invention provides strains of commercial mushrooms whose genetic material comprises genes from more than one species. These strains include a novel strain of the commercial mushroom genus Agaricus which is a cellular hybrid produced by fusion between protoplasts of two different Agaricus species. In another embodiment, this invention provides improved strains for commercial production of mushroom fruit which are progeny from crosses of Agaricus sp. with a cellular hybrid produced by fusion between protoplasts of two different species of the genus Agaricus.
