Venn diagram of the highly expressed unigenes at the three different pollen developmental stages of four ginger species, Caulokaempferia coenobialis (Cco), Hornstedtia hainanensis (Hhn), Pyrgophyllum yunnanense (Pyn), and Zingiber nudicarpum (Znu). The overlaps represent unigenes simultaneously highly expressed in more than one species. A microspore mother cell stage; B tetrad stage; C bicellular pollen stage
