profile for the proteins produced by the strains. 5508032 BACILLUS THURINGIENSIS ISOLATES ACTIVE AGAINST COCKROACHES Schnepf H Ernest; Randall John B; Payne Jewel M San Diego, CA, UNITED Mycogen STATES assigned to Corporation The subject invention concerns novel materials and methods for the control of cockroaches. Cockroaches are common house pests, and they create problems in hospitals, the food industry and in agriculture. According to the subject invention, activated toxins of Bacillus thuringiensis var. israelensis (B.t.i.) are used to control cockroaches. In one embodiment, the subject invention also concerns the use of B.t. PS123Dl to control cockroaches. A truncated form of a toxin obtained from PSl23Dl having particular activity to cockroaches is also claimed for use in controlling the pest.
5508189 REGENERATION OF PLANTS FROM CULTURED GUARD CELL PROTOPLASTS Tallman John STATES University

on callus medium with excellent results. Root and shoot propagation may be obtained from established guard cell callus. With the establishment of roots and shoots, an entire plant may be regenerated from its guard cells. Guard cells may also be cultured for transplant gene extraction as a gene donor used to alter the characteristics of the recipient plant.
5512279 BIOLOGICAL CONTROL OF DIPTERAN PESTS OF THE GENUS LYCORIELLA USING BACILLUS THURINGIENSIS Jarrett Paul; White Philip; Pethybridge Nicole J West Sussex, UNITED KINGDOM assigned to Agricultural Genetics Company Limited PCT No. PCT/GB91/01957 Sec. 371 Date Apr. 15, 1993 Sec. 102(e) Date Apr. 15, 1993 PCT Filed Nov. 7, 1991 PCT Pub. No. WO92/08354 PCT Pub. Date May 29, 1992. The invention relates to the biological control of Dipteran pests other than the mosquito, which comprises the use of Bacillus thuringiensis isolate HD 541 (NCIMB 40373) or HD 571 (NCIMB 40374), or a mutant, recombinant or derivative thereof, or insecticidal material derived therefrom.

IN VITRO LEAF PETIOLE MULTIPLICATION OF PELARGONIUMS Oglevee-O’Donovan Wendy; stoats Eleanor Scottdale, PA, UNITED STATES assigned to Oglevee Ltd A process for propagating Pelargonium x domesticum varieties by tissue culture propagation of petiole sections taken from a mother plant. In addition to tissue culture propagation steps and growth media constituents which are known in the art, an essential step of the preferred embodiment of the invention includes the conducting of callus formation by initial culturing of the petiole section in the dark. In all embodiments of the invention, however, it is believed that the effectiveness of the present process is attributable at least in part to the presence in the culture medium of a growth regulator selected from the consisting of amino or group benzyl-glucosides and aminoor benzyl-glycosides or any other composition chemically equivalent to the exemplary regulator benzylamino riboside.
5520938 LOW CHOLESTEROL EGGS AND METHOD OF SELECTING SAME Brunnquell John R Port Washington, WI, UNITED STATES assigned to Wisconsin Alumni Research Foundation Reduced cholesterol, low fat eggs are obtained. At least a twenty-five percent reduction in cholesterol is achieved over normal levels for the grade size. The reduction can be achieved by weight monitoring of the egg, size monitoring of the yolk through candling, and selecting eggs from high producing, young, and high clutch chickens.
5523226 TRANSGENIC SWINE COMPOSITIONS AND METHODS Wheeler Matthew B Tolono, IL, UNITED STATES assigned to Biotechnology Research and Development Carp; Board of Trustees of the University of Illinois Transgenic swine, and compositions and methods for making and using sameare provided. Central to the invention are porcine (Sus scrofa) embryonic stem cell lines and methods for establishing them. Cells of such lines are transformed with exogenous genetic material of interest and then used to provide chimeric swine, which have germ cells comprising the exogenous genetic material. The chimeric swine are bred to provide transgenic swine. Transgenic swine of the invention can be used to provide human proteins or peptide hormones or can be used as xenograft donors.
