Method of producing transformed cell or plant body of maize, nucleic acid construct, and method of introducing nucleic acid into cell or plant body of maize

A nucleic acid construct for reducing abnormality of a phenotype of maize, comprising:

• 1) a nucleic acid encoding an amino acid sequence of SEQ ID NO:
• 2, or a nucleic acid encoding a polypeptide that includes an amino acid sequence having at least 95% sequence identity with the amino acid sequence of SEQ ID NO:
• 2, the polypeptide having a function of promoting cell division of maize, or
• 2) a nucleic acid encoding an amino acid sequence of SEQ ID NO:
• 15, or a nucleic acid encoding a polypeptide that includes an amino acid sequence having at least 95% sequence identity with the amino acid sequence of SEQ ID NO:
• 15, the polypeptide having a function of promoting cell division of maize;
• and
• a promoter that includes a 35S promoter sequence of Cauliflower mosaic virus for producing a nucleic acid in maize,
• wherein a polypeptide that includes the amino acid sequence of SEQ ID NO:
• 2 reduces abnormality of a phenotype of the maize compared to a case in which the nucleic acid is overexpressed in a cell or plant body of maize under the control of a promoter other than the promoter that includes the 35S promoter sequence of the Cauliflower mosaic virus,
• wherein the polypeptide that includes an amino acid sequence having at least 95% sequence identity with the amino acid sequence of SEQ ID NO:
• 2 reduces the abnormality of the phenotype of the maize compared to a case in which the nucleic acid is overexpressed in the cell or plant body of maize under the control of the promoter other than the promoter that includes the 35S promoter sequence of the Cauliflower mosaic virus,
• wherein a polypeptide that includes the amino acid sequence of SEQ ID NO:
• 15 reduces the abnormality of the phenotype of the maize compared to a case in which the nucleic acid is overexpressed in the cell or plant body of maize under the control of a promoter other than the promoter that includes the 35S promoter sequence of the Cauliflower mosaic virus, and
• wherein the polypeptide that includes an amino acid sequence having at least 95% sequence identity with the amino acid sequence of SEQ ID NO:
• 15 reduces the abnormality of the phenotype of the maize compared to a case in which the nucleic acid is overexpressed in the cell or plant body of maize under the control of the promoter other than the promoter that includes the 35S promoter sequence of the Cauliflower mosaic virus, and
• wherein a resulting maize plant that is created by overexpressing the nucleic acid exhibits a morphologically normal phenotype and fertility.
