1/10 Size Plant growing tech. completed by Institute of Physical and Chemical Research

It pays attention to prompting growth by using "Gibberellin" of the growth hormone for the improvement of breed of the vegetable and grain such as the grasses that cannot be thrown out in the research consortium in the reason laboratory. This gibberellin was examined in detail in the research consortium. The research consortium made it block the gibberellin in the plant with low stature and work and discovered the enzyme had without to be. When the research consortium examined whether this enzyme was produced with what kind of mechanism further, "GAMT1" "GAMT2"2 kinds of genes were understood with the cause.

Then, to actually generate a large amount of these "GAMT1" "GAMT2" in Arabidopsis thaliana, the cigarette, and the petunia, the kind has been improved in the group. Then, the gibberellin was suppressed usually, and it became the mini plant of the size of about 1/10 in the plant. In addition, it has usually returned to the size when the gibberellin is added from the outside to those mini plants. In a word, it is shown that this can control the size of the plant.

The usual the one that GAMT1 was excessively generated by Arabidopsis thaliana (left), one (right).

The usual the one that GAMT1 was excessively generated by petunia (on the left), one (right).

For instance, "Rafreshia called the world's largest flower is raised by potted" etc. will become possible by applying "GAMT1" "GAMT2" that suppresses the growth of the plant to other plants.
