Conserved regulatory mechanism controls the development of cells with rooting functions in land plants [Plant Biology]

21-Jul-2015 | Thomas Ho Yuen Tam; Bruno Catarino; Liam Dolan, Proceedings of the National Academy of Sciences current issue, 2015

Land plants develop filamentous cells—root hairs, rhizoids, and caulonemata—at the interface with the soil. Members of the group XI basic helix–loop–helix (bHLH) transcription factors encoded by LOTUS JAPONICUS ROOTHAIRLESS1-LIKE (LRL) genes positively regulate the development of root hairs in ...

microRNAs and inherited retinal dystrophies [Genetics]

21-Jul-2015 | Shunbin Xu, Proceedings of the National Academy of Sciences current issue, 2015

Inherited retinal dystrophies (IRD) are a heterogeneous group of blinding diseases that affect more than 200,000 Americans and millions worldwide (1). Identification of genes that are responsible for IRD when defective is of great importance to the basic understanding as well as development of ...

Highly compacted biodegradable DNA nanoparticles capable of overcoming the mucus barrier for inhaled lung gene therapy [Medical Sciences]

14-Jul-2015 | Panagiotis Mastorakos; Adriana L. da Silva; Jane Chisholm; Eric Song; Won Kyu Choi; Michael P. Boyle; Marcelo M. Mor ..., Proceedings of the National Academy of Sciences current issue, 2015

Gene therapy has emerged as an alternative for the treatment of diseases refractory to conventional therapeutics. Synthetic nanoparticle-based gene delivery systems offer highly tunable platforms for the delivery of therapeutic genes. However, the inability to achieve sustained, high-level ...

Role of RAG1 autoubiquitination in V(D)J recombination [Biochemistry]

14-Jul-2015 | Samarendra K. Singh; Martin Gellert, Proceedings of the National Academy of Sciences current issue, 2015

The variable domains of Ig and T-cell receptor genes in vertebrates are assembled from gene fragments by the V(D)J recombination process. The RAG1–RAG2 recombinase (RAG1/2) initiates this recombination by cutting DNA at the borders of recombination signal sequences (RSS) and their neighboring ...

Attenuation of dengue (and other RNA viruses) with codon pair recoding can be explained by increased CpG/UpA dinucleotide frequencies [Biological Sciences]

14-Jul-2015 | Peter Simmonds; Fiona Tulloch; David J. Evans; Martin D. Ryan, Proceedings of the National Academy of Sciences current issue, 2015

Shen et al. (1) describe the modification of three regions of the Dengue virus type 2 (DENV-2) genome to match the codon pair use of insect genes rather than those of mammals. We have previously shown that such recoding also modifies frequencies of CpG and UpA dinucleotides and have proposed...

Structural asymmetry in a conserved signaling system that regulates division, replication, and virulence of an intracellular pathogen [Microbiology]

14-Jul-2015 | Jonathan W. Willett; Julien Herrou; Ariane Briegel; Grant Rotskoff; Sean Crosson, Proceedings of the National Academy of Sciences current issue, 2015

We have functionally and structurally defined an essential protein phosphorelay that regulates expression of genes required for growth, division, and intracellular survival of the global zoonotic pathogen Brucella abortus. Our study delineates phosphoryl transfer through this molecular pathway, ...

Structural basis for the activation of the C. elegans noncanonical cytoplasmic poly(A)-polymerase GLD-2 by GLD-3 [Biochemistry]

14-Jul-2015 | Katharina Nakel; Fabien Bonneau; Christian R. Eckmann; Elena Conti, Proceedings of the National Academy of Sciences current issue, 2015

The Caenorhabditis elegans germ-line development defective (GLD)-2–GLD-3 complex up-regulates the expression of genes required for meiotic progression. GLD-2–GLD-3 acts by extending the short poly(A) tail of germ-line–specific mRNAs, switching them from a dormant state into a translationally ...

Miniaturized mitogenome of the parasitic plant Viscum scurruloideum is extremely divergent and dynamic and has lost all nad genes [Evolution]

07-Jul-2015 | Elizabeth Skippington; Todd J. Barkman; Danny W. Rice; Jeffrey D. Palmer, Proceedings of the National Academy of Sciences current issue, 2015

Despite the enormous diversity among parasitic angiosperms in form and structure, life-history strategies, and plastid genomes, little is known about the diversity of their mitogenomes. We report the sequence of the wonderfully bizarre mitogenome of the hemiparasitic aerial mistletoe Viscum ...

Assessing niche width of endothermic fish from genes to ecosystem [Ecology]

07-Jul-2015 | Daniel J. Madigan; Aaron B. Carlisle; Luke D. Gardner; Nishad Jayasundara; Fiorenza Micheli; Kurt M. Schaefer; Danie ..., Proceedings of the National Academy of Sciences current issue, 2015

Endothermy in vertebrates has been postulated to confer physiological and ecological advantages. In endothermic fish, niche expansion into cooler waters is correlated with specific physiological traits and is hypothesized to lead to greater foraging success and increased fitness. Using the ...

Structural analysis of a class III preQ1 riboswitch reveals an aptamer distant from a ribosome-binding site regulated by fast dynamics [Biophysics and Computational Biology]

07-Jul-2015 | Joseph A. Liberman; Krishna C. Suddala; Asaminew Aytenfisu; Dalen Chan; Ivan A. Belashov; Mohammad Salim; David H. M ..., Proceedings of the National Academy of Sciences current issue, 2015

PreQ1-III riboswitches are newly identified RNA elements that control bacterial genes in response to preQ1 (7-aminomethyl-7-deazaguanine), a precursor to the essential hypermodified tRNA base queuosine. Although numerous riboswitches fold as H-type or HLout-type pseudoknots that integrate ...
