Future space missions and implementation of permanent bases on Moon and Mars will greatly depend on the availability of ambient air and sustainable food supply. Therefore, understanding the effects of altered gravity conditions on plant metabolism and growth is vital for space missions and extra-terrestrial human existence. In this mini-review we summarize how plant cells are thought to perceive changes in magnitude and orientation of the gravity vector. The particular advantages of several single-celled model systems for gravity research are explored and an overview over recent advancements and potential use of these systems is provided.
未来的太空任务以及在月球和火星上建立永久基地将在很大程度上依赖于周围空气的可用性和可持续的食物供应。因此，了解改变重力条件对植物代谢和生长的影响对于太空任务和地球外人类的生存至关重要。在这篇迷你综述中，我们总结了植物细胞如何感知重力矢量大小和方向的变化。探讨了几种单细胞模式系统在重力研究方面的特殊优势，并提供了这些系统的最新进展和潜在应用的概述。
