International ClassesA01H 005/00C12N 015/11 C12N 015/82 AbstractA method for modifying a foreign nucleotide sequence for enhanced accumulation of its protein product in a monocotyledonous plant and/or increasing the frequency of obtaining transgenic monocotyledonous plants which accumulate useful amounts of a transgenic protein by reducing the frequency of the rare and semi-rare monocotyledonous codons in the foreign gene and replacing them with more preferred monocotyledonous codons is disclosed. In addition, a method for enhancing the accumulation of a polypeptide encoded by a nucleotide sequence in a monocotyledonous plant and/or increasing the frequency of obtaining transgenic monocotyledonous plants which accumulate useful amounts of a transgenic protein by analyzing the coding sequence in successive six nucleotide fragments and altering the sequence based on the frequency of appearance of the six-mers as to the frequency of appearance of the rarest 284, 484, and 664 six-mers in monocotyledonous plants is provided. Also disclosed are novel structural genes which encode insecticidal proteins of B. t. k. and monocotyledonous (e.g. maize) plants containing such novel structural genes.Other References
