China Space Station is expected to achieve space rice "from seeds to seeds" whole life cycle training experiment

CCTV News: In the past sixty years, scientists 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. At present, only a few crops of rapeseed, wheat and peas have completed the experiment from seeds to seeds in space. The significance of the Chinese Space Station's space experiment is that for the first time, it is necessary to realize the training experiments of the whole life cycle of rice "from seeds to seeds" under the condition of space micro -gravity.

There is such a instrument at the Molecular Science Innovation Center of the Chinese Academy of Sciences, which is specifically used to simulate the growth of plants in the condition of micro -gravity.

Zheng Huiqiong, a researcher at the Molecular Science Innovation Center of the Chinese Academy of Sciences: This is a rotor. Its role is to simulate the micro -gravity effect of the space. After all, the experimental opportunity of space is very precious, and it takes a long time to do an experiment in the sky, so we created such a instrument on the ground to simulate the impact on plants after losing the direction. However, after all, the gravity still exists, and can only simulate the part of the space, so in the end, we must understand the impact of the space environment on plants, and we must go to space to do it. Essence

This project focuses on three key scientific issues: how does micro -gravity affect flowering? What is the molecular mechanism that affects the flowering of plants? Can it be used to control the flowering of plants with a micro -gravity environment? Focusing on these three key scientific issues, through the function of analyzing and more gravity in the process of plant flowering, the molecular foundation and key genes of micro -gravity regulating flowering flowers are obtained, so as to provide theoretical guidance for planting grain planting in space in the future.

Zheng Huiqiong, a researcher at the Molecular Science Innovation Center of the Chinese Academy of Sciences: In the next step, we are sampled in the glove box through astronauts. We samples in two cases: one is a flowering period, picks the leaves back, and then comes back to analyze it after freezing. The changes in these genes and proteins in space compare with the ground. Come back to analyze and analyze the seed conditions. This time we hope to successfully receive the seeds of rice in the space, so that we will complete the cultivation of the whole life cycle of rice "from seeds to seeds".
