Figure 2From: Heterologous hybridisation to a Pinus microarray: profiling of gene expression in Pinus radiata saplings exposed to ethephonNumber of differentially expressed gene cohorts in the various sample tissues. The value in the overlapping portions of the circles corresponds to the number of co-expressed gene cohorts in each treatment pair. Legend: UR, upregulated; DR, downregulated; Mxylem, mucilaginous xylem; 1 and 8 weeks after treatment.Back to article page
