Abstract: The invention herein includes a general method for reducing or eliminating a toxic effect of transgenic defensin expression in a host plant. The invention also includes a method of modifying a nucleic acid encoding a defensin, a nucleic acid modified thereby and a modified defensin encoded by the modified nucleic acid sequence. The invention also includes a transgenic plant containing and expressing the modified defensin-coding nucleic acid sequence, the plant exhibiting reduced or eliminated toxic effects of defensin, compared with otherwise comparable transgenic plants expressing an unmodified defensin. The modified defensin is termed a chimeric defensin having a mature defensin domain of a first plant defensin combined with a C-terminal propeptide domain of a second plant defensin or a vacuolar translocation peptide.

Abstract: Methods for fostering somatic embryogenic competence of a plant cell or tissue by contacting the plant cell or tissue with an arabinogalactan protein (AGP) composition effective for fostering somatic embryogenic competence in plant species and varieties that are recalcitrant to somatic embryogenesis and/or regeneration are provided. AGP compositions useful for fostering somatic embryogenic competence are provided, including total AGP and an AGP RP-HPLC hydrophobic fraction, both from embryogenic callus, from plant varieties including cotton lines Coker 315, Siokra 1-4, and Sicala 40, including at concentrations ranging from about 0.0008 mg/L to about 100 mg/L. Methods for regenerating plants, producing transformed plants, and impeding somatic embryogenic competence are also provided. Plant culture media and methods for making useful AGP compositions and media are also provided. Amino acid and nucleotide sequences for peptides and proteins eluting in hydrophobic AGP fractions are also provided.

Abstract: Abrasive properties of co-fused alumina zirconia are improved by the addition of from 0.1 to 2% of Y.sub.2 O.sub.3 to the fusion mix and quenching the fused product. Y.sub.2 O.sub.3 ores containing mostly Y.sub.2 O.sub.3 with lesser amounts of rare earth oxides can be substituted for high purity Y.sub.2 O.sub.3.
