Cover of the American Journal of Botany Special Issue for February 2012 (image) Botanical Society of America Share Print E-Mail Caption A visualization of relative gene expression among three species of the legume genus Glycine: an allotetraploid (blue) and its diploid progenitors (red and yellow). Per-cell expression level is represented by the surface area of the circles, one circle for each gene model × species combination, and mapped onto 44,326 gene models across the 20 chromosomes of the closely related reference genome of Glycine max (soybean).
