Abstract: The invention relates to a plant-colonizing microorganism which has been genetically engineered to integrate into the chromosome of such microorganism, DNA derived from B. thuringiensis coding for protein toxin. The genetically engineered plant-colonizing microorganisms of the invention, and their progeny, proliferate in commensal or non-detrimental relationship with the plant in the plant environment and are insecticidally active against a subspecies of insect pest which are harmful to the plant. The invention further relates to insecticidal compositions containing such plant-colonizing microorganisms as the active insecticidal agent and to a method of using such genetically engineered plant-colonizing microorganisms in a method of killing or inhibiting insect pests.

Abstract: Variant somatotropins are described in which the asparagine located in the 95-101 region are replaced by glutamine which somatotropins exhibits enhanced stability.

Abstract: Variant forms of mammalian somatotropins, particularly bovine and porcine somatotropin, in which the asparagine located between positions 95-101 has been replaced by glutamine exhibit enhanced stability at high pH and at elevated temperatures while retaining bioactivity equivalent to the corresponding unmutated somatotropins, and are useful in the treatment of animals to enhance growth and/or milk production.

Abstract: A method for regenerating soybean plants from cotyledonary nodes is disclosed. Soybean seeds are germinated on nutrient medium containing a cytokinin to produce a donor plant. The cotyledonary nodes of the donor plant are excised and divided into pieces. The cotyledonary node pieces are cultured on nutrient medium containing a cytokinin until callus tissue develops which contains shoots. The shoots are removed and rooted on nutrient medium free of exogenous hormone to form a plantlet.

Abstract: A method of recovering biologically active somatotropins which are produced as insoluble refractile bodies in transformed microorganisms which comprises dissolving refractile bodies in a denaturant and 2-amino-2-methyl-1-propanol, homogenizing, and diluting to fold.

Abstract: This invention involves a cloning or expression vector comprising a gene which encodes 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) polypeptide which, when expressed in a plant cell contains a chloroplast transit peptide which allows the polypeptide, or an enzymatically active portion thereof, to be transported from the cytoplasm of the plant cell into a chloroplast in the plant cell, and confers a substantial degree of glyphosate resistance upon the plant cell and plants regenerated therefrom.The EPSPS coding sequence may be ligated to a strong promoter, such as the 35S promoter from cauliflower mosaic virus, to create a chimeric gene. Such genes can be inserted into plant transformation vectors, and subsequently introduced into plant cells. Plant cells transformed using such genes and plants regenerated therefrom have been shown to exhibit a substantial degree of glyphosate resistance.
