Figure 4.

Defense 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 genes involved in defense: (a) ICS2 and (b) CRK11 expression increases with peak expression at 0.65 g while (c) CML8 expression levels decrease with a dip at 0.65 g.
