The present invention relates to dsRNA molecules for inhibiting the expression of CYP51 gene(s) from a fungal or oomycete phytopathogen and the use of such inhibitory dsRNA molecules for controlling phytopathogenic fungi and/or oomycetes. The present invention further relates to DNA sequences providing a transcriptional template for inhibitory dsRNA molecules or antisense RNA; and phytopathogen-tolerant transgenic plants with such DNA sequences.

Disclosed are methods of making a modified lecithin by conducting an enzymatic conversion of a naturally derived lecithin to form a modified lecithin, e.g., having an enhanced level of phosphatidylethanolamine, phosphatidylserine, or a combination thereof. Compositions prepared from the modified lecithin and use to inhibit lipid oxidation are described.

The present invention relates to a method for preparing 7-dehydrocholesterol and/or the biosynthetic intermediates and/or secondary products thereof by culturing organisms, in particular yeasts. Furthermore, the invention relates to the preparation of the nucleic acid constructs required for preparing the genetically modified organisms and to said genetically modified organisms, in particular yeasts, themselves.

This disclosure concerns nucleic acid molecules and methods of use thereof for control of pathogens through RNA interference-mediated inhibition of target coding and transcribed non-coding sequences in pathogens. The disclosure also concerns methods for applying dsRNA through formulations and/or transgenic plants that express nucleic acid molecules useful for the control of pathogens, and the plant cells and plants obtained thereby.
