Figure 5.

Cell wall-related genes with fractional g responses. Each dot on the graph shows the normalized gene expression level for the transcription factor in the sixteen microgravity replicates (µg), and the four replicates at 0.53 g, 0.65 g, and 0.88 g. The red line indicates the mean expression level in that gravity level. Shown are three representative cell wall-associated genes: (a) PGL3 which increases linearly with increasing g levels and two pectin lyase genes, (b) At3g59580 and (c) At3g61490, which show highest expression in microgravity and then decrease.
