Phylogenetic Profiling

PCR-based approach was used as a phylogenetic profiling tool to probe genomic DNA samples from representatives of evolutionary distant moss taxa, namely, classes Bryopsida, Tetraphidopsida, Polytrichopsida, Andreaeopsida, and Sphagnopsida. We found relatives of allPhyscomitrella patensmiR390 and TAS3-like loci in these plant taxa excluding Sphagnopsida. Importantly, cloning and sequencing ofMarchantia polymorphagenomic DNA showed miR390 and TAS3-like sequences which were also found among genomic reads ofM. polymorphaat NCBI database. Our data suggest that the ancient plant miR390-dependent TAS molecular machinery firstly evolved to target AP2-like mRNAs in Marchantiophyta and only then both ARF- and AP2-specific mRNAs in mosses. The presented analysis shows that moss TAS3 families may undergone losses of tasiAP2 sites during evolution toward ferns and seed plants. These data confirm that miR390-guided genes coding for ARF- and AP2-specific ta-siRNAs have been gradually changed during land plant evolution.

Phylogenetic Profiling

Transacting siRNA loci (TAS3-like) of a particular plant species are usually represented by several gene families. PCR-based approach was used as a phylogenetic profiling tool to probe genomic DNA samples from representatives of evolutionary distant Bryophyta taxa, namely, class Bryopsida (subclasses Bryidae and Dicranidae) and class Sphagnopsida. We found relatives of all four Physcomitrella patens (subclass Funariidae) TAS3-like loci in subclasses Bryidae and Dicranidae. Only representatives of subclass Bryidae encoded TAS3-like genes belonging to P. patens TAS3a and TAS3d families. On the other hand, only the members of order Grimmiales (subclass Dicranidae) encoded gene relatives of P. patens TAS3c family. These data indicate that moss ta-siRNA families have been long conserved during land plant evolution. However, P. patens TAS3-like loci were detected neither in two Sphagnum species from the earliest diverged moss class Sphagnopsida, nor in the Selaginella kraussiana from the earliest extant tracheophyta lineage, Lycopodiopsida.
