Appeal No. 93-2460
Application No. 07/590,647
46. A method for selectively controlling weeds in a field
containing a crop having planted crop seeds or plants comprising
the steps of:
planting said crop seeds or plants which are glyphosate
tolerant as a result of containing a gene encoding a glyphosate-
tolerant EPSP synthase enzyme which contains the amino acid
sequence -L-G-N-A-A-T-A- between positions 80 and 120 in the
mature EPSP synthase sequence, and a second amino acid sequence
-A-L-L-M-X -A-P-L-T-, where X is either alanine, serine or1 1
threonine, and where said second amino acid sequence is located
between positions 170 and 210 in the mature EPSP synthase
sequence; and
applying to said crop and weeds in said field a sufficient
amount of glyphosate to control said weeds without significantly
affecting said crop.
47. The method of Claim 46 wherein said gene encoding a
glyphosate-tolerant EPSP synthase enzyme is from a plant source.
48. The method for producing a gene of Claim 1 which
comprises making the indicated codon substitutions in a EPSP
synthase gene encoding a protein of Figure 1.
