Protein involved in restoration of cytoplasmic male sterility to fertility and gene encoding the protein and gene

An isolated DNA encoding a protein involved in restoration of a cytoplasmic male sterile individual to fertility, selected from the group consisting of:

• (1) an isolated DNA which encodes a protein having the amino acid sequence of SEQ ID NO. 26;
• (2) an isolated DNA which encodes a protein having an amino acid sequence that is 92% or more homologous to the amino acid sequence of SEQ ID NO. 26;
• (3) an isolated DNA having 95% of or higher homology to a DNA sequence encoding a protein having the amino acid sequence of SEQ ID NO. 26;
• (4) an isolated DNA which encodes a protein having the amino acid sequence of SEQ ID NO. 19;
• (5) an isolated DNA which encodes a protein having an amino acid sequence that is 92% or more homologous to the amino acid sequence of SEQ ID NO. 19;
• (6) an isolated DNA having 95% or higher homology to a DNA sequence encoding a protein having the amino acid sequence of SEQ ID NO. 19;
• (7) an isolated DNA having the nucleotide sequence of SEQ ID NO. 18;
• and
• (8) an isolated DNA having 95% or higher homology to the nucleotide sequence of SEQ ID NO. 18.
