Abstract: The present invention provides compositions comprising randomized in-frame fusion polynucleotides and methods for introducing them into a host organism to obtain desirable phenotypic changes that modulate tolerance to stress, thus creating novel characteristics of the transformed organism.

Abstract: A method for making a chitosan product from yeast cells is disclosed herein. Yeast cells are cultured to form a biomass of yeast cells. The yeast cells are induced to undergo meiosis causing the yeast cells to form asci containing ascospores wherein each ascospore contains a chitosan protective layer in the ascospore wall. Chitosan is extracted from the ascospores, purified to form purified chitosan, and precipitated and dried to form a chitosan product.

Abstract: The present invention provides polynucleotides isolated from eucaryotic organisms which are structural genes or promoters. Such isolated polynucleotides are particularly useful in the modification of gene expression in plants. This invention also relates to compositions isolated from plants and their use in the modification of gene activation and/or expression. In a specific embodiment, the subject invention provides plant polynucleotide sequences encoding promoters that are components of the cellular activation and transcription apparatus and the use of such polynucleotide sequences in the modification of expression of genes.

Abstract: The present invention relates to the isolation and identification of a short integuments protein and the nucleic acid which encodes such protein. The invention also relates to an expression vector containing the encoding nucleic acid and methods whereby plant fertility, fecundity and flowering time are increased or decreased by transformation of plants with that nucleic acid or variants thereof. The present invention also relates to transgenic cells, plants, and seeds containing the short integuments gene of the present invention.
