Adult sex ratios and mortality differences

Adult sex ratios and mortality differences

Across tetrapods, ZZ/ZW sex-determination systems are associated with a more male-skewed adult sex ratio than XY/XX systems. Phylogenetic analyses of a large dataset from tetrapod species in the wild, by Ivett Pipoly, Tamás Székely, András Liker and colleagues, reveal an influence of sex-determination system on adult sex ratio via sex-biased adult mortality.

Spatiotemporal gene patterns during Vibrio biofilm development

Biofilms are bacterial communities that live attached to surfaces and are important for disease development. Grace Johnson, Bonnie Bassler and co-workers develop imaging technology to probe spatiotemporal patterns of Vibrio cholerae biofilm gene expression, showing that temporal and spatial patterns are established by quorum sensing and cyclic-di-GMP signaling, respectively.

Reverse gear for Trypanosome phosphofructokinase

ATP-dependent phosphofructokinase (PFK) is considered an irreversible glycolytic enzyme. Nicolas Plazolles, Frédéric Bringaud and co-authors show that Trypanosoma brucei is the only known organism that uses PFK in the gluconeogenic direction under physiological conditions, likely due to its compartmentalization within glycosomes.

Postnatal whisker cortex development

Salwan Butrus, Hannah R. Monday, Christopher Yoo, Daniel Feldman and Karthik Shekhar provide a transcriptomic atlas of the developing mouse barrel cortex, identifying temporal gene expression changes during postnatal maturation. Sensory experience minimally affects neuronal cell type maturation and conserved molecular mechanisms underlie cortical development and plasticity.

Smooth muscle calcineurin and hypertension

Calcineurin is a phosphatase that has been implicated in hypertension and angiotensin-II-induced abdominal aortic aneurysms (AAA). Paula Sofía Yunes-Leites, Yilin Sun, Juan Miguel Redondo, Miguel Campanero and colleagues reveal a novel, phosphatase-independent mechanism by which calcineurin contributes to AAA, dependent on its transcriptional reprogramming of smooth muscle cells.

Upstream ORFs and circadian rhythms

Oscillations of core clock genes, including Clock (Clk), are essential for the generation of circadian rhythms. Yuanqiang Sun, Ke Shui, Jian Lu, Luoying Zhang and co-workers reveal that upstream open reading frames are enriched in Drosophila circadian genes, and that they repress Clk protein translation and thereby influence circadian gene expression and behavior.

Nucleosomal poly (dA:dT) drives H2A.Z deposition

How is the H2A.Z histone variant targeted to specific sites in the genome by the SWR chromatin remodeler? Cynthia Converso, Leonidas Pierrakeas, Ed Luk and co-authors show that DNA sequences contribute to the substrate specificity of SWR across the yeast genome and that its H2A.Z insertion activity is stimulated by polyadenine tracks in nucleosomes. Don't miss the related Primer by Blaine Bartholomew.

Is pathogen prediction possible?

To what extent can we predict future pathogenic microbes? Arturo Casadevall discusses why complex requirements for virulence and dynamic host-microbe interactions make probabilistic predictions difficult, but not impossible.

Consensus View

Naming rods and cones

Vertebrate photoreceptors have been studied for well over a century, but a fixed nomenclature across species has been lacking. This Consensus View proposes a new consolidated and pan-vertebrate naming system for the rod and cone photoreceptors of the eye.

A refined picture of interferon

Interferon is a central component of the vertebrate antiviral response. John Schoggins highlights recent findings that suggest a refined ‘limited set’ model of its activity, in which distinct viruses are targeted by small subsets of the induced gene repertoire.

Editorial

Vaccines work… and do not cause autism

Vaccines have saved millions of lives, yet their importance and safety is repeatedly in question. This editorial argues that we cannot let disinformation campaigns get in the way of global public health.
