By controlling expression of various functions of plants, we provide technologies for stabilizing and enhancing the production of our livelihoods, such as food, clothing items, essential items in living environments (e.g. wood and paper) and fuels.
By establishing technologies that accelerate the Calvin cycle function, which is the major path of photosynthesis, and effectively assimilate and stabilize CO2 in the air, we propose solutions for environmental issues at the global level, such as increasing needs for food production and reduction of CO2.
Concerning the mechanism that regulates photosynthesis, we identified that the key enzyme among the enzymes involved in the Calvin cycle is fructose 1,6-bisphosphate aldolase and determined that expression of the Calvin cycle function is regulated by the bonding of fructose 1,6-bisphosphate aldolase and the glutathione molecule.
Currently, research institutions and companies in Japan and overseas in various subfields within the agriculture and forestry industry are exploring ways in which the basic technologies to activate productivity of plants can be put in practical use. As such, creation of revolutionary techniques in practical application of such technologies by Japanese institutions is highly anticipated.
- Specifically, we offer technologies that
- promote the growth of cultivated plants
- enhance plant productivity
- promote flower-bud formation
- enhance the quality of plants (e.g. enhanced sugar production and increased size of fruits)
- increase biomass
- enhance stress tolerance
- create vernalization effects
- create seed priming effects
Our technologies can be applied in areas such as seed treatment, seedling development, agriculture, horticulture, trees, and plants that are associated with non-farming activities (e.g. grass).
- Our products include
- Glutathione disulfide (GSSG)
- Glutathione (GSH)
- Gene encoding glutathion–binding plastidic 1,6-bisphosphate aldolase (FBA1 gene)
- Gene encoding gamma-glutamylcysteine synthetase (GSH1 gene)
Among the products listed above, the methods for processing plants with Glutathione are the same as the traditional methods of administrating fertilizers and agricultural chemicals. For instance, methods such as foliar treatment, soil application, soil drenching, and application on water surface can be used with Glutathione.
Glutathione was treated on one foliole of the trifoliolate of soy leaves. The assimilation and stabilization of CO2 were examined by measuring 11C-labelled CO2 intake at two hours and four hours after the application of the glutathione.
A 50% increase in assimilation and stabilization of CO2 was found in the soy leaves with the glutathione application compared to the soy leaves without the glutathione application.
