          Interference 103,579                                                        
               Claims 4, 6, 21 and 23 of Hofvander’s involved application9            
          and Claim 23 of Visser’s involved application10 stand designated            
          as corresponding to the count.  Visser’s Preliminary Motion 2               
          (VPM 2)(Paper No. 18) for judgment that Claim 6 of Hofvander’s              
          involved application, filed November 24, 1993, is unpatentable              
          under 35 U.S.C. § 102 over Hergersberg (VDX 1)) or Hovenkamp-               
          Hermelink (VDX 9); and/or under 35 U.S.C. § 103 in view of the              
          combined teachings of Hergersberg, Hovenkamp-Hermelink, Visser’s            
          PhD Thesis (VDX 7), and van der Leij (VDX 3); was dismissed as              

               9    4.  A fragment of a potato gene coding for granule-               
                         bound starch synthase (GBSS), wherein said                   
                         fragment is selected from the group consisting               
                         of SEQ ID No. 1, SEQ ID No. 2 and SEQ ID No. 3.              
                    6.  Isolated potato gene coding for granule-bound                 
                         starch synthase in potato (GBSS gene) having the             
                         nucleotide sequence stated in SEQ ID No. 5.                  
                    21.  A method for tuber-specific expression of a                  
                         gene product in potato, comprising transforming              
                         said potato with a DNA molecule comprising an                
                         isolated promoter from the potato gene coding                
                         for granule-bound starch synthase (GBSS).                    

                    23.  A method for tuber-specific expression of a gene             
                         product in potato, comprising transforming said              
                         potato with a DNA molecule comprising an isolated            
                         promotor [sic] from the potato gene coding for               
                         granule-bound starch synthase (GBSS), said                   
                         promoter having the nucleotide sequence stated in            
                         SEQ ID No. 4.                                                
               10   23. A homologous construct of the potato plant                    
                         comprising a full length potato granule-bound                
                         starch synthase (PGBSS) cDNA or genomic DNA.                 
                                        -62-
