Spaceflight differentially regulates xyloglucan and xylan genes

Transcriptomic and proteomic studies show that genes encoding xyloglucan endotransglucosylases, glycosyl hydrolases, AG proteins, and proteins involved in xylan biosynthesis are differentially regulated or upregulated by spaceflight in A. thaliana roots.
