Selection and hybridization shaped the rapid spread of African honey bee ancestry in the Americas

Compared to European subspecies, honey bees adapted to the lowlands of southern and eastern Africa (Apis mellifera scutellata) preferentially forage for pollen over nectar and store little honey for winter. Foraging behavior is one of many divergently evolved traits that may contribute to a natural climatic range limit for scutellata-European hybrid honey bees, which spread rapidly out of Brazil in the 1950s and today dominate across tropical (but not temperate) regions in the Americas.

Stability of SARS-CoV-2 phylogenies

Here, Turakhia and colleagues present a toolkit to compare, analyze and combine SARS-CoV-2 phylogenies, identify and remove potential sequencing errors, and establish a stable clade structure.

RNA-directed DNA Methylation

In the latest PLOS Genetics Topic Page, Robert Erdmann and Colette Picard outline RNA-directed DNA methylation (RdDM) - a biological process in which non-coding RNA molecules direct the addition of DNA methylation to specific DNA sequences. See the Wikipedia entry here.

The STRIPAK signaling complex regulates dephosphorylation of GUL1, an RNA-binding protein that shuttles on endosomes

In eukaryotes, the striatin-interacting phosphatase and kinase (STRIPAK) multi-subunit signaling complex controls a variety of developmental processes. Stein et al. investigated Sordaria macrospora mutants that lack one or two STRIPAK subunits and provide new fundamental insights into the mechanism of how GUL1, as a STRIPAK target, controls multiple cellular functions.

Review

New insights into the function of mammalian Argonaute2

The recently solved crystallographic structure of Ago2 and a high-throughput analysis that used repurposed sequencing techniques has brought us closer to achieving the goal of uncovering the mechanisms that recognise an miRNA target.
