Fig. 1From: Conservation and divergence of small RNA pathways and microRNAs in land plantsPhylogeny of green plants showing the species included in this study. Phylogeny was adopted from the new classification of extant lycophytes and ferns as described in [21]. The taxonomy (family and order) of each species is shown to the right of the full species names. Higher taxonomic ranks are labeled on the tree. The leptosporangiate ferns form the largest class of ferns, the Polypodiopsida. Purple, green algae; light blue, bryophytes; magenta, lycophytes; red, Polypodiales (ferns); green, Salviniales (ferns); orange, angiosperms; black, other ferns and gymnospermsBack to article page
