               altering the coding sequence of a Bt gene to make that Bt              
               gene more plant-like by introducing plant preferred codons             
               is reflected in the statement ‘It appears that for efficient           
               expression of this toxin in tobacco plants the coding                  
               sequence must be modified to eliminate premature termination           
               of transcription.’ . . . This statement was removed from the           
               abstract before it was submitted because this statement                
               would have revealed our conception regarding our Bt gene               
               modification method to the public at a time when we were               
               diligently reducing that conception to practice.                       
               (3) Dr. Adang declared (AR 6878, para. 6):                             
                    Following my conception of the invention with Dr.                 
               Murray in November 1985, I sought to determine which                   
               sequence differences were present between Bt and plant                 
               genes, and the regions of the gene which would require                 
               modifications using the methods we had conceived to                    
               increase Bt expression in the transgenic plants.  I                    
               performed several computer analyses of Bt genes, including             
               generating codon usage tables, and determined that the                 
               Bt genes had a strong preference for nucleotides A and T               
               in the wobble position, and were generally rich in AT                  
               sequences compared to plants . . . .                                   
               (4)  Dr. Adang further declared (AR 6878-6879, para. 7-9):             
                    (a) “In December of 1985, I also examined Bt genes for            
               the presence of transcriptional stop sites within the coding           
               sequence which would be modified using plant preferred                 
               codons . . . [;]”                                                      
                    (b) “From December of 1985 into January of 1986, I                
               performed sequence comparisons between the cloned Bt genes             
               to determine if consensus sequences were present in the                
               coding regions which would need modification . . . [;]” and            
                    (c)  From March of 1986 through December of 1987, I               
               performed sequence analyses of Bt genes to identify RNA                
               destabilizing sequences which would need to be reduced                 
               and/or eliminated to enable increased Bt gene expression.              
               In addition, I continued sequence analyses and comparisons             
               of the Bt genes.  Other sequence analyses to locate RNA                
               destabilizing sequences in Bt genes were performed by                  
               other Agrigenetics scientists.  These efforts are reflected            
               in . . . computer searches . . . .”
