Поліплоїдізація ДНК
Improvement of plant production by inducing DNA polyploidization
Plant growth is associated with DNA polyploidization, which is also called endoreplication
Wild species |
Cultivated species |
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
Cell enlargement
Organ enlargement
Improved crop production:
- 570kg/100m2
- 30% increase in yield
