Abstract

Living organisms have evolved in the presence of constant gravity (1g) on Earth and their growth is related to rate of ribosome, protein biosynthesis, and regulation of cell cycle phases. Microgravity does not have the same effects on different phases of cell cycle such that activity of some phases is increased. It changes the number of cell cycles per time. In the cell growth process, rate of ribosome biosynthesis is decreased under simulated microgravity and a large variation is observed in abundance of nucleolar proteins (Nucleolin and Fibrillarin). Under normal conditions, growth and cell division are coupled, and microgravity uncouples these processes. The study of plant cellular response can help improvement of biological knowledge and preparation of life support systems in space.
