Abstract:
1. A method for selecting a plant of the family of Solanaceae containing a gene involved in conferring potyvirus resistance, comprising: (A) detecting in a test plant of the family of Solanaceae the presence or the absence of a mutant eIF4E protein or a mutant allele encoding said eIF4E protein, and (B) selecting a plant in which a mutant eIF4E protein, or a mutant allele encoding said mutant eIF4E protein, is detected; wherein said mutant eIF4E protein contains the substitution of a neutral amino acid residue at least one position selected from the group consisting of position 2, 3, 4, 5, 7, 9, 10, 11, 12, 13, 14, 15, 16, 18, 19, 20, 21, 22, 23, 24, 25, 28, 29, 30, 31, 32, 33, 34, 35, 38, 39, 41, 42, 43, 44 and 45 of SEQ ID NO: 1 with a charged amino acid, or the substitution of a charged amino acid residue at least one position selected from the group consisting of position 1, 6, 8, 17, 26, 27, 36, 37, 40 and 46 of SEQ ID NO: 1 with a neutral amino acid or an amino acid having an opposite charge.
