A kind of floating rice grown in places such as southern China and Southeast Asia can "water up" during the rainy season each year, and the top leaves can quickly extend out of the water to avoid being completely submerged. An international research group recently published a report in the online version of the US "Science" magazine, saying that they uncovered the special growth mechanism of floating rice. The survival of plants is inseparable from water, but the floods can cause many plants to suffer the disaster of extinction. A kind of floating rice grown in places such as southern China and Southeast Asia has the peculiar ability to cope with floods such as "water grows and grows." It can quickly grow several meters high during the rainy season and floods, and let the top leaves protrude from the water. This magical characteristic aroused the interest of scientists. The research, which was conducted by institutions such as Nagoya University and the Institute of Physics and Chemistry in Japan, found that a special gene, the semi-dwarf gene SD1, played a key role in this process. When the flood floods the floating rice, under the action of this gene, the floating rice will produce a lot of SD1 protein. This protein has the function of synthesizing the phytohormone gibberellin, which can make plants elongate. Although this protein is also present in ordinary rice, the activity of gibberellin synthesis in floating rice SD1 protein is much higher, which can more strongly promote plant growth. Over thousands of years of history, floating rice has evolved this unique ability to adapt to rainy and flooded environments. In recent years, abnormal weather has occurred frequently all over the world. The research team believes that this research not only helps the scientific community to develop higher-yielding floating rice, but also can be used to develop rice breeding technologies that adapt to different environments.
