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 all Physcomitrella patens miR390 and TAS3-like loci in these plant taxa excluding Sphagnopsida. Importantly, cloning and sequencing of Marchantia polymorpha genomic DNA showed miR390 and TAS3-like sequences which were also found among… 
TAS3 miR390-dependent loci in non-vascular land plants: towards a comprehensive reconstruction of the gene evolutionary history
TLDR
It is hypothesized that the appearance of TAS3-related sequences could take place at a very early step in evolutionary transition from charophyte algae to an earliest common ancestor of land plants, and bioinformatic and experimental PCR-based approaches were used as tools to analyze TAS2 and TAS6 loci.
The Emergence, Evolution, and Diversification of the miR390-TAS3-ARF Pathway in Land Plants
TLDR
Deep evolutionary analysis of the highly conserved miR390-TAS3-ARF pathway identifies the point of emergence and adaption of each of the components in the pathway, and inferred a potential bidirectional processing mechanism exists for some TAS3 genes.
Profiling and Characterization of Small RNAs in the Liverwort, Marchantia polymorpha, Belonging to the First Diverged Land Plants.
TLDR
The results suggested that two genes in the SPL transcription factor family were targeted by two distinct miRNAs in M. polymorpha, suggesting that balanced expression of miRNA/target mRNAs has a crucial role in developmental regulation in M-polymorpha.
The emergence, evolution, and diversification of the miR390-TAS3-ARF pathway in land plants
TLDR
The evolutionary path of the miR390-TAS3-ARF pathway in land plants is illuminated, and significant variation that occurs in the production of phasiRNAs in plants is demonstrated, even in the functionally important and archetypal miR 390-TasiARF regulatory circuit.
Identification of miRNAs and Their Targets in the Liverwort Marchantia polymorpha by Integrating RNA-Seq and Degradome Analyses
TLDR
This study provides a foundation for further investigations of the RNA-mediated silencing mechanism in M. polymorpha as well as of the evolution of this gene silencing pathway in embryophytes.
MicroRNAs in Marchantia polymorpha.
TLDR
Application of artificial miRNA and CRISPR-Cas9 technologies in genetic studies of M. polymorpha provide avenues to further investigate miRNA biology, indicating that these pathways existed in the ancestral land plant.
Sequencing of small RNAs of the fern Pleopeltis minima (Polypodiaceae) offers insight into the evolution of the microRNA repertoire in land plants
TLDR
The small RNA fraction of an epiphytic South American fern is sequenced and compared to plant miRNA databases, allowing for the identification of miRNA families that are shared by all land plants, share by all vascular plants (tracheophytes) or shared by euphyllophytes (ferns and seed plants) only.
Sequencing of small RNAs of the fern Pleopeltis minima (Polypodiaceae) offers insight into the evolution of the microrna repertoire in land plants
TLDR
This work sequenced the small RNA fraction of an epiphytic South American fern and compared it to plant miRNA databases, allowing for the identification of miRNA families that areshared by all land plants, shared by all vascular plants (tracheophytes) or shared by euphyllophytes (ferns and seed plants) only.
Extensive Families of miRNAs and PHAS Loci in Norway Spruce Demonstrate the Origins of Complex phasiRNA Networks in Seed Plants
TLDR
Analysis of the small RNA population in the ancient gymnosperm Norway spruce suggests a dual function of miR482/miR2118 present in gymnosperms that was selectively yet divergently retained in flowering plants, and expands the understanding of phasiRNA network in plants and the evolution of plant miRNAs, particularly miR402-TAS3 and its functional diversification.
Identification of miRNAs and their targets in transgenic Brassica napus and its acceptor (Westar) by high-throughput sequencing and degradome analysis
TLDR
The present study increases the number of miRNAs identified in B. napus and suggests that there are possible differences in the miRNA expression between transgenic B. Westar and its transgenic cultivar.

TLDR
Phylogenetic analysis indicated that several genome/gene duplication events have been involved in the expansion of TAS3 genes while some TAs3 genes might have been lost during evolution of the grass family.
The Selaginella Genome Identifies Genetic Changes Associated with the Evolution of Vascular Plants
TLDR
The genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported, is reported, finding that the transition from a gametophytes- to a sporophyte-dominated life cycle required far fewer new genes than the Transition from a non Seed vascular to a flowering plant.

TLDR
The discovery that nearly half of the gene families in the ancestor of flowering plants have been lost in at least one species examined indicates that the repertoires of miRNA genes have changed more dynamically than previously thought during plant evolution.
Novel miR390-Dependent Transacting siRNA Precursors in Plants Revealed by a PCR-Based Experimental Approach and Database Analysis
TLDR
A novel type of miR390-dependent TAS sequences was identified in dicots, characterized by a smaller distance betweenMiR390 sites compared to TAS3, a single copy of ta-siARF, and a sequence conservation pattern pointing to the possibility that processing of novel TAS-like locus is initiated by cleavage of the 5′-terminal miR 390 target site.
