First Claim
Patent Images
1. A method to confer formaldehyde resistance to a plant comprising the steps of;
- introducing genes encoding hexulose-6-phosphate synthase and 6-phosphohexulose isomerase into the plant and having the genes expressed in the chloroplast of the plant, thereby the ability to assimilate formaldehyde into an intermediate of the Calvin cycle is conferred to the plant.

Abstract
According to this invention, by introducing genes encoding hexulose-6-phosphate synthase and 6-phosphohexulose isomerase into a plant to have the genes expressed in the chloroplast of the plant, a transgenic plant having a pathway to assimilate formaldehyde through the Calvin cycle is provided. The transgenic plant according to this invention has resistance to formaldehyde and is capable of reducing the level of environmental formaldehyde significantly. Therefore, it is assumed that the transgenic plant according to this invention can be used to purify environmental condition, by placing it in a residence or in an office.

- 3. A transgenic plant having resistance against formaldehyde, in which genes encoding hexulose-6-phosphate synthase and 6-phosphohexulose isomerase are introduced into the plant to have the genes expressed in the chloroplast of the plant, thereby the ability to assimilate formaldehyde into an intermediate of Calvin cycle is rendered to the plant.
