It's so high!

"Global Times" reporter learned from the Chinese Academy of Sciences on the 29th that on July 24, the experimental sample of the experimental sample of the experimental compartment of the Chinese Space Station asked the sample of the south mustard seeds and rice seeds. High-rod rice seedlings have grown to about 30 cm high, and the dwarf rice rice is also 5-6 cm tall. The growth state is good. In the future, the experiment of the entire life cycle of "from seeds to seeds" in space and rice will be completed. During the experiment, the astronauts collected samples and frozen preservation, and finally returned to the ground with the astronauts to analyze.

According to a reporter from the Global Times, on the questioning of the "Molecular Flowing Molecular Mechanism of Higher Plant Flowers under the Micro Gravity Conditions of Molecular Plant Science Innovation Center of the Chinese Academy of Sciences, the Molecular Flower Mechanism of the Chinese Academy of Sciences. On July 28, experimental units containing experimental samples and rice seeds were installed in the life and ecological experimental module of Life Ecological Ecology, which asked about the experimental compartment, and launched the experiment on July 29 through the ground program.

Zheng Huiqiong, a researcher at the Chinese Academy of Sciences Molecular Plant Excellence Center and the "Molecular Mechanism of Higher Plant Flowing and Control" Experimental Project of "Micro Gravity Conditions", said in an interview with the media that Arabida Mustard represents Gemini, long days, and cross flower plants, Many vegetables, such as vegetables, rapeseeds, etc. belong to the family of Cross Flowers. The rice represents the leaf leaves, short -day, and grasses, and many grain crops, such as wheat and corn, belong to the grace. This experimental project mainly studies the molecular mechanism of the flowering regulation of Arabisha and rice under the micro -gravity conditions of the space. "Blossom" is the prerequisite for plants to make a new generation of seeds.

In the case of micro -gravity, the growth and development of Arabia must

"The seeds of crops are both food and the carrier of the next generation. With the deepening of the development of manned deep space detection, such as landing in Mars, if you want to truly solve the problem of food guarantee for human long -term space exploration, you cannot simply rely on the earth to carry from the earth. Grain to meet the long -term space life and work needs of aerospace members, and the problem of food production in space must be solved. Because the life of the earth cannot survive without protective land under the conditions of severe space environment, the production of space crops in the future must be completely in full In the closed artificial environment, the planting space and energy supply are very scarce. Therefore, the crops of space planting must have the requirements of high -yield, high -quality, high production efficiency and low energy consumption. "Zheng Huiqiong said.

In the past 60 years, scientists around the world have conducted a lot of research on space planting and cultivation plants, and have conducted more than 20 plant training experiments among various space aircraft. However, only a few crops in rapeseed, wheat and peas have completed the "from seeds to seeds" experiments in space. At the same time, under the conditions of space, problems such as delayed flowering time, low number of flowers, low seeds of seeds, and decreased seed quality are still not overcome.

Researcher Zheng Huiqiong introduced that through the research on crop experimenting at the Chinese Space Station this time, under the international minimum gravity conditions in the world, the cultivation experiments from "seeds to seeds" throughout the life cycle were completed. Parameters provide important theoretical guidance to further analysis of the impact of space micro -gravity on rice growth and molecular basis, and use rice to provide important theoretical guidance. At the same time, through the transcription group analysis, the two modes of Arabidopsis and rice, the expression of the key genes of key genes in the space environment and the changes in its regulatory network, and analyzes the molecular mechanism of the spatial micro -gravity for long and short -day plants. Further create a theoretical basis for the development of crops and development and use of space micro -gravity environment resources.
