- Differential gene expression patterns in white spruce newly formed tissue on board the International Space Station.
Plain Language Summary
White spruce is an important species in the forest industry and its genetics are well known. This makes it an ideal candidate for testing the effect of gravity on its development.
Thus, in 2010, white spruce seedlings spent 30 days aboard the International Space Station, and their growth was compared to that of similar seedlings that remained on Earth.
The researchers noted "normal" growth in both cases (on Earth and in space), but there were differences in gene expression, i.e. in the way the information contained in a gene is decoded. This affects the functioning and development of cells, which could have an effect on wood formation.
