A Novel STAY-GREEN Gene and Method for Preparing Stay-green Transgenic Plants

摘要

The present invention is a plant of aging upon the leaves of chlorophyll (chlorophyll) catabolism to engage the leaves of the sulfide to induce a new SGR (S TAY-GR EEN) gene and the SGR gene mutation or, SGR gene expression suppression to , or SGR neutralize the protein encoded by the gene to the manufacturing method of the switch green sustained transformed plant characterized in that it is maintained open green during aging of the leaves (stay-green transgenic plant), and the green produced by the above method It relates to a mutant plant. ; According to the invention, takes place in the plant leaves sulfide the decomposition of chlorophyll during aging of the leaves ; In the variation to the SGR gene, or to suppress the expression of the SGR gene, or ; Neutralize the protein encoded by the SGR gene room by a sulfide of a plant leaf ; It not to the green can be maintained long. ; SGR gene, a mutant green sustainability
