Method for producing transgenic surface layer chimeric plant
A rose is produced in which an introduced gene is only present in a part of the cells thereof, such as cells of the L1 layer of flower petals, but is not present in germ cells such as pollen cells or ovule cells. Since the introduced gene is not propagated to other roses even when this rose is crossed with other roses, the possibility of dispersal of the introduced gene can be completely negated.
1. A rose that contains a foreign gene in cells of the L1 layer, but not in pollen cells and ovule cells, wherein the foreign gene is at least one of a flavonoid 3′,5′-hydroxylase gene from a plant belonging to the violet family, and an aromatic acyl group transferase gene from a plant belonging to the snapdragon family.
2. The rose of claim 1 , wherein the rose is Rosa hybrida.
3. The rose of claim 2 , wherein the rose is a hybrid tea rose, a floribunda, or a miniature rose.
4. The rose of claim 1 , wherein the flavonoid 3′,5′-hydroxylase gene is from a pansy.
5. The rose of claim 1 , wherein the aromatic acyl group transferase gene is from a torenia.
6. A method for producing the rose of claim 1 , comprising
introducing the foreign gene into the rose mediated by Agrobacterium , and
selecting the rose in which the foreign gene is only present in cells of the L1 layer.
7. The rose of claim 1 , wherein the flavonoid 3′,5′-hydroxylase gene comprises the nucleic acid sequence of SEQ ID NO: 4.
8. The rose of claim 1 , wherein the flavonoid 3′,5′-hydroxylase gene encodes a flavonoid 3′,5′-hydroxylase comprising the amino acid sequence of SEQ ID NO: 19.
9. The rose of claim 1 , wherein the aromatic acyl group transferase gene comprises the nucleic acid sequence of SEQ ID NO: 3.
10. The rose of claim 1 , wherein the aromatic acyl group transferase gene encodes an aromatic acyl group transferase comprising the amino acid sequence of SEQ ID NO: 18.
