Abstract

Plants will form the basis of artificial ecosystems in space exploration and the creation of bases on other planets. Astrophysical factors, such as ionizing radiation (IR), magnetic fields (MF) and gravity, can significantly affect the growth and development of plants beyond Earth. However, to date, the ways in which these factors influence plants remain largely unexplored. The review shows that, despite the lack of specialized receptors, plants are able to perceive changes in astrophysical factors. Potential mechanisms for perceiving changes in IR, MF and gravity levels are considered. The main pathway for inducing effects in plants is caused by primary physicochemical reactions and change in the levels of secondary messengers, including ROS and Ca2+. The presence of common components, including secondary messengers, in the chain of responses to astrophysical factors determines the complex nature of the response under their combined action. The analysis performed and the proposed hypothesis will help in planning space missions, as well as identifying the most important areas of research in space biology.

植物信号系统在响应关键天体物理因素中的作用:电离辐射增加、近零磁场和微重力。
植物将成为太空探索和在其他星球上建立基地的人工生态系统的基础。电离辐射(IR)、磁场(MF)和重力等天体物理因素会极大地影响地球以外植物的生长和发育。然而,迄今为止,这些因素影响植物的方式在很大程度上仍未得到探索。综述表明,尽管缺乏专门的受体,植物仍能感知天体物理因子的变化。文中探讨了感知红外、中频和重力水平变化的潜在机制。对植物产生影响的主要途径是初级物理化学反应和次级信使(包括 ROS 和 Ca2+)水平的变化。在对天体物理因素的反应链中,存在包括次级信使在内的共同成分,这决定了在它们的共同作用下反应的复杂性。所做的分析和提出的假设将有助于规划空间飞行任务,并确定空间生物学最重要的研究领域。
