A key feature of RNA interference is its ability to spread from cell to cell. Such non-cell-autonomous gene silencing has been characterized extensively in both plants and animals, but the identity of the mobile silencing signal has remained elusive. Several recent studies now shed light on the identity of this signal in plants, and indicate that small

The illustration that accompanied the review by C. C. Albritton, Jr., of W. H. Goetzmann and K. Sloan's Looking Far North (Viking, New York, 1982) in the issue of 10 December, page 1109, should have been credited to the Bancroft Library, University of California, Berkeley, as well as to the book under review.

Spermatogenesis is characterized by meiotic divisions and major morphological changes to produce spermatozoa that are capable of independent movement and fertilization of an egg. Male germ cell differentiation is governed by orchestrated, phase-specific gene expression patterns that are tightly controlled at transcriptional and post-transcriptional ...

RNA cleavage by small catalytic RNAs
Current Opinion in Structural Biology, 1995Recent studies of the hammerhead ribozyme have provided an insight into its three-dimensional structure. In addition, studies using chemical probes, functional-group modification and mutational analysis, in combination with computer modelling, have led to proposals for the structure of both the hairpin and hepatitis delta virus ribozymes.

Resources for Small Regulatory RNAs
Current Protocols in Molecular Biology, 2009AbstractIn the past fifteen years, new classes of regulatory RNAs have been discovered, previously hidden in the transcriptome mostly due to their small size. These small regulatory RNAs include small interfering RNAs (siRNAs), microRNAs (miRNAs), and Piwi‐interacting RNAs (piRNAs).

Many small RNA species associate with the nucleolar structure. Some of these small nucleolar RNAs (snoRNAs) are required for cleavage processing of ribosomal RNA precursors. There are many pseudouridine residues and methylated riboses in mature ribosomal RNA.

A growing list of small nucleolar RNAs (snoRNAs) has been characterized in eukaryotes. They are transcribed by RNA polymerase II or III; some snoRNAs are encoded in the introns of other genes. The nonintronic polymerase II transcribed snoRNAs receive a trimethylguanosine cap, probably in the nucleus, and move to the nucleolus.

Small Nuclear RNAs and RNA Processing
1983I. Summary Ribosomal RNA, transfer RNA, and messenger RNAs, which comprise about 99% of the cellular RNA, are part of the protein-synthesizing machinery. Many studies in the last 15 years have established the presence of another class of RNA, “small nuclear RNAs” (snRNAs) that account for 0.1-1% of the total cellular RNA.
