Fig. 3From: Comprehensive survey and evolutionary analysis of genome-wide miRNA genes from ten diploid Oryza speciesPhylogenetic relationships among the AA-, BB- and FF-genomes of Oryza based on the precursor sequences of non-conserved-miR812a (a) and conserved-miR156l (b). The evolutionary history was inferred with the Neighbor-Joining method using MEGA6. Both the tree topologies depict BB- and FF-genomes as the eminent outgroups, whereas O. longistaminata can be seen as the earliest divergent species among the AA-genomesBack to article page
