Fig. 1From: Evolutionary research on the expansin protein family during the plant transition to land provides new insights into the development of Tartary buckwheat fruitPhylogeny and diversity of expansin proteins in 12 species. A species tree was constructed using the online software TIMETREE (http://www.timetree.org/). The number of members in different subfamilies is expressed by a color scale. The blue, green, gray, light green and orange colors represent algae, Bryophyta, early angiosperms, monocotyledons and dicotyledons, respectivelyBack to article page
