Abstract
The object of an embodiment of the present invention is to improve the quality of a tobacco product. The present invention relates to a tobacco plant in which a mutation is introduced in a genome, the mutation causing suppression of a function of a specific endogenous gene.
Claims19
A tobacco plant in which a mutation is introduced in a genome, the mutation causing suppression of a function of at least any one of:
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 1;
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 2;
- and
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 3.
A method of producing a tobacco plant, comprising the step of introducing a mutation into a genome of a tobacco plant, the mutation causing suppression of a function of at least any one of:
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 1;
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 2;
- and
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 3.
A cured leaf which is obtained from a tobacco plant,
- in the cured leaf, a mutation being introduced in a genome, the mutation causing suppression of a function of at least any one of:
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 1;
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 2;
- and
- an endogenous gene which contains, as a coding region, a polynucleotide that encodes a polypeptide having a sequence identity of 80% or higher with an amino acid sequence represented by SEQ ID NO:
- 3,
- the cured leaf having a higher total carotenoid content than a cured leaf which is obtained from a wild-type tobacco plant.
