Humans have been committed to space exploration and to find the next planet suitable for human survival. The construction of an ecosystem that adapts to the long-term survival of human beings in space stations or other planets would be the first step. The space plant cultivation system is the key component of an ecosystem, which will produce food, fiber, edible oil and oxygen for future space inhabitants. Many plant experiments have been carried out under a stimulated or real environment of altered gravity, including at microgravity (0 g), Moon gravity (0.17 g) and Mars gravity (0.38 g). How plants sense gravity and change under stress environment of altered gravity were summarized in this review. However, many challenges remain regarding human missions to the Moon or Mars. Our group conducted the first plant experiment under real Moon gravity (0.17 g) in 2019. One of the cotton seeds successfully germinated and produced a green seedling, which represents the first green leaf produced by mankind on the Moon.
人类一直致力于太空探索，以寻找下一个适合人类生存的星球。在空间站或其他行星上构建适应人类长期生存的生态系统将是第一步。太空植物培养系统是生态系统的关键组成部分，它将为未来的太空居民生产食物、纤维、食用油和氧气。已经在模拟或真实的改变重力环境下进行了许多植物实验，包括微重力（0g）、月球重力（0.17g）和火星重力（0.38g）。本综述总结了植物在改变重力环境下如何感知重力并发生变化。然而，对于人类前往月球或火星的任务，仍然存在许多挑战。我们的团队在 2019 年首次在真实的月球重力（0.17g）下进行了植物实验。其中一颗棉花种子成功发芽并长出了绿色的幼苗，这代表了人类在月球上首次产生的绿叶。
