    摘要： The present invention relates to DNA molecules of plant origin encoding a modified 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) enzyme wherein the a first EPSPS coding sequence that normally encodes a threonine residue of a mature EPSPS sequence is modified to encode isoleucine of the mature EPSPS sequence, and a second EPSPS coding sequence that normally encodes a proline residue of a mature EPSPS sequence is modified to encode serine of the mature EPSPS sequence, wherein the first and second residues are respectively located at relatively positions 102 and 106 of a mature EPSPS sequence encoded by said DNA molecule; and the production of a transgenic plant resistant or tolerant to a herbicide of the phosphonomethylglycine family, e.g., glyphosate. The mutated enzyme, which substantially maintains the catalytic activity of the wild-type enzyme, allows for increased tolerance or tolerance of the plant to a herbicide of the phosphonomethylglycine family, and allows for the substantially normal growth or development of the plant, its organs, tissues or cells.

    摘要： The present invention relates to novel yeast strains, methods and genetic constructs for their preparation, and their use for the synthesis or modification of steroidal compounds. More particularly, the invention describes strains having a reduced 20αHSD type activity, in particular by modifying the GCY1 and/or YPR1 genes. The yeast strains of the invention make it possible to improve the efficiency of the synthesis or to increase the selectivity or the yields of the method, as well as the quality of the final product. The strains, methods and compounds of the invention are useful in the search for, the development and the production of products with therapeutic or prophylactic activity, in humans or animals, in particular of steroidal derivatives.
