MicroRNAs (miRNAs) are a unique class of short endogenous RNAs, which have become
known in the past few decades as major players in gene regulation at the post …

MicroR159 (miR159) is ancient, being present in the majority of land plants where it targets
a class of regulatory genes called GAMYB or GAMYB-like via highly conserved miR159 …

Nonrecombining sex chromosomes, like the mammalian Y, often lose genes and
accumulate transposable elements, a process termed degeneration. The correlation …

The domination of the landmasses of Earth by plants starting during the Ordovician Period
drastically altered the development of the biosphere and the composition of the atmosphere …

Highlights•Most miRNAs are lineage-specific.•MIR genes evolve rapidly and show much
divergence.•MIR genes may keep originating from target genes.•miRNA–target pairs may co …

MicroRNA408 (miR408) is an ancient and highly conserved miRNA, which is involved in the
regulation of plant growth, development and stress response. However, previous research …

High‐throughput RNA sequencing (RNA‐seq) has recently become the method of choice to
define and analyze transcriptomes. For the model moss Physcomitrella patens, although this …

Background As key regulators of gene expression in eukaryotes, small RNAs have been
characterized in many seed plants, and pathways for their biogenesis, degradation, and …

Liverworts comprise one of six primary land plant lineages, with the predicted origin of extant
liverwort diversity dating to the Silurian. The ancestral liverwort has been inferred to have …

As a conserved microRNA (miRNA) family in plants, miR408 is known to be involved in
different abiotic stress responses, including drought. Interestingly, some studies indicated a …
