DNA polyploidization

DNA polyploidization

Improvement of plant production by inducing DNA polyploidization

Plant growth is associated with DNA polyploidization, which is also called endoreplication

DNA polyploidization causes somatic cells to increase their size

Repeated DNA replication without intervening mitosis or cytokinesis

Growth promotion by induced DNA polyploidization

Verification using model plants

• Whole genome sequence determined
• Established methods for gene introduction
• Plants can be grown in small space in laboratory
• A lot of resource for

• Identification of new genes inducing DNA polyploidization
• Artificial induction of DNA polyploidization
• Growth promotion by induced polyploidization
• Optimizing the grow promotion

Applying to useful plants

Improved crop production:

• 570kg/100m²
• 30% increase in yield
