Bacteriophage, bacterial wilt disease control agent, and bacterial wilt disease control method

Abstract

Bacteriophages that comprise a tail fiber protein sequence comprising a C terminus host recognition site described by SEQ ID NO: 1 and which infect Ralstonia solanacearum which causes bacterial wilt disease are disclosed. Compositions comprising these bacteriophages may be employed as wilt control agents. Methods for preventing or treating diseases caused by Ralstonia solanacearum such as bacterial wilt disease are also disclosed. A bacterial wilt disease control method in a plant may include administering such bacteriophages to a plant or to a plant growth medium and can be effective against a wide variety of Ralstonia solanacearum strains. Nucleic acids encoding the C terminus host recognition site and amino acid sequences comprising the host recognition site are also disclosed.
