Phylogenetic distribution of conserved Brazilian pine miRNAs. The grid indicates the presence (blue squares) or absence (white squares) of miRNA families in bryophytes (gray branch), lycopods (orange branch), ferns (purple branch), gymnosperms (red branches), and angiosperms (green branches). The cladogram illustrates phylogenetic relationships among these groups and is based on Axtell and Meyers (2018). Dark blue squares indicate gymnosperm-specific miRNAs. Data from A. thaliana, G. max, O. sativa, Z. mays, A. trichopoda, P. abies, S. moellendorffii, and P. patens were obtained in miRBase release 22.0 (Kozomara and Griffiths-Jones, 2014). Conserved miRNAs from the other species were reported in the literature: C. lanceolata (Wan et al., 2012a), T. maierei (Hao et al., 2012), G. biloba (Zhang et al., 2015), P. minima (Berruezo et al., 2017).
