Rolling-circle replication of viroids, viroid-like satellite RNAs and hepatitis delta virus: variations on a theme [PDF]
Viroids and viroid-like satellite RNAs from plants, and the human hepatitis delta virus (HDV) RNA share some properties that include small size, circularity and replication through a rolling-circle mechanism.

A split ribozyme system for in vivo plant RNA imaging and genetic engineering
Summary RNA plays a central role in plants, governing various cellular and physiological processes. Monitoring its dynamic abundance provides a discerning understanding of molecular mechanisms underlying plant responses to internal (developmental) and external (environmental) stimuli, paving the way for advances in plant biotechnology to engineer crops

A high-throughput, quantitative cell-based screen for efficient tailoring of RNA device activity [PDF]
Recent advances have demonstrated the use of RNA-based control devices to program sophisticated cellular functions; however, the efficiency with which these devices can be quantitatively tailored has limited their broader implementation in cellular ...

Genetic control of mammalian T-cell proliferation with synthetic RNA regulatory systems [PDF]
RNA molecules perform diverse regulatory functions in natural biological systems, and numerous synthetic RNA-based control devices that integrate sensing and gene-regulatory functions have been demonstrated, predominantly in bacteria and yeast.

Ubiquitous presence of the hammerhead ribozyme motif along the tree of life.
Examples of small self-cleaving RNAs embedded in noncoding regions already have been found to be involved in the control of gene expression, although their origin remains uncertain.

Discovery of replicating circular RNAs by RNA-seq and computational algorithms. [PDF]
Replicating circular RNAs are independent plant pathogens known as viroids, or act to modulate the pathogenesis of plant and animal viruses as their satellite RNAs.
