Crystal structures of a group II intron lariat primed for reverse splicing
Maria Costa; Hélène Walbott; Dario Monachello; Eric Westhof; François Michel
<jats:title>Tie me up, cut me down</jats:title> <jats:p> Group II in trons are mobile genetic elements found in all domains of life. They are large ribozymes that can excise themselves from host RNA. Costa <jats:italic>et al.</jats:italic> determined the structure of an excised group II intron in its branched conformation. This conformation is comparable to the branched “lariat” seen during the splicing of nuclear RNA transcripts. The lariat conformation helps assemble the group II active site for the reverse splicing reaction. The lariat in spliceosomal splicing may also have a similar role in the second step of messenger RNA intron removal. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.aaf9258">10.1126/science.aaf9258</jats:related-article> </jats:p>

Intracellular innate immune surveillance devices in plants and animals
Jonathan D. G. Jones; Russell E. Vance; Jeffery L. Dangl
<jats:title>Shared logic in diverse immune systems</jats:title> <jats:p> The innate immune systems of both plants and animals depend on the ability to recognize pathogen-derived molecules and stimulate a defense response. Jones <jats:italic>et al.</jats:italic> review how that common function is achieved in such diverse kingdoms by similar molecules. The recognition system is built for hair-trigger sensitivity and constructed in a modular manner. Understanding such features could be useful in building new pathways through synthetic biology, whether for broadening disease defenses or constructing new signal-response circuits. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.aaf6395">10.1126/science.aaf6395</jats:related-article> </jats:p>
