Living cells exposed to the microgravity of space for limited time show changes in function and
structure. This suggests that alterations in cell metabolism, immune cell function, cell division,
and cell attachment have occurred. Among plant hormones, brassinosteroids are structurally the
most similar to animal steroid hormones. Like its animal counterparts, it regulates the expression
at numerous genes, impacts the activity of complex metabolic pathways, contributes to the
regulation of cell division and differentiation, and helps control overall developmental programs
leading to morphogenesis. The addition of brassinolide can help reverse or prevent the
alterations of plants exposed to microgravity and space. A rotating clinostat was prepared to
expose plants to a simulated microgravity environment. Brassinolide was added to determine
whether it could prevent the alterations of microgravity. Also tested was a control group, and
gibberillic acid as a standard. Over the past decades, scientists have discovered that space flights
have wide-ranging effects on living systems. Through millions of years of evolution, most
terrestrial organisms have adapted to function optimally in the presence of a constant gravitation
field, but little is known about the effects of the absence of gravity, and even more so, how to
prevent it.
