Tropisms are growth-mediated plant movements that help plants to respond to changes in
environmental stimuli. The availability of water and light, as well as the presence of a …

Nucleoli are nuclear domains present in almost all eukaryotic cells. They not only specialize
in the production of ribosomal subunits but also play roles in many fundamental cellular …

Plant stress responses are a key factor in steering the development of cells, tissues, and
organs. However, the stress-induced signal transduction cascades that control localized …

Seeds of Arabidopsis thaliana were sent to space and germinated in orbit. Seedlings grew
for 4d and were then fixed in-flight with paraformaldehyde. The experiment was replicated …

Environmental gravity modulates plant growth and development, and these processes are
influenced by the balance between cell proliferation and differentiation in meristems …

Dozens of box C/D small nucleolar RNAs (snoRNAs) have recently been found in
eukaryotes (vertebrates, yeast), ancient eukaryotes (trypanosomes) and archae, that …

Recently, the ribosomes—molecularly well-characterized cell organelles where the process
of translation of messenger RNA into polypeptides occurs—have attracted new interest …

Background Cell growth and cell proliferation are intimately linked in the presence of Earth's
gravity, but are decoupled under the microgravity conditions present in orbiting spacecraft …

The nucleolus is a nuclear substructure that is well known as the ribosome factory of the cell,
namely, the site in which the production of mature ribosomal subunits takes place before …

Changes in the cell growth rate of an in vitro cellular system in Arabidopsis thaliana induced
by short exposure to an altered gravity environment have been estimated by a novel …
