Characterization of ori and parS-like functions in secondary genome replicons in Deinococcus radioduransAn array of direct repeats upstream to parAB operon helps in secondary genome elements’ maintenance independent of primary chromosome in multipartite genome harboring bacterium Deinococcus radiodurans.
Incipient sympatric speciation in wild barley caused by geological-edaphic divergenceSympatric speciation is still contentious but here based on genome-wide analysis; we show incipient sympatric speciation of an emerging new wild barley species from Hordeum spontaneum, the progenitor of all cultivated barleys at “Evolution Plateau” (EP), Upper Galilee, Israel.
Predicting gene regulatory networks from cell atlasesIntegrated single-cell gene regulatory network from three mouse cell atlases captures global and cell type–specific regulatory modules and crosstalk, important for cellular identity.
multicrispr: gRNA design for prime editing and parallel targeting of thousands of targetsA bioinformatics R package for a fast and generic guideRNA design, optimized for large-scale perturbation assays.
Peptide-based quorum sensing systems in Paenibacillus polymyxaDiscovery of conserved communication systems in the agriculturally important Paenibacillus bacteria. These systems are widespread, and some species encode more than 25 different peptide-receptor pairs.
Exploiting somatic piRNAs in Bemisia tabaci enables novel gene silencing through RNA feedingRNAi usually relies on Dicer-produced siRNAs to induce gene silencing. In many arthropods, another type of RNAi is present in the soma—the piRNA pathway. This work finds exploiting this biology is a viable alternative for gene knockdown.
An evolutionary approach to systematic discovery of novel deubiquitinases, applied to LegionellaThe analysis of the relationships between different deubiquitinase classes leads to the definition of an aromatic “gatekeeper” motif that distinguishes DUBs from other cysteine proteases and helps to predict new bacterial DUBs.
Multiple sclerosis risk variants regulate gene expression in innate and adaptive immune cellsThis comprehensive study identifies multiple sclerosis risk expression quantitative trait loci in purified immune cell types.
MAPK pathway mutations in head and neck cancer affect immune microenvironments and ErbB3 signalingMAPK mutations favor HNSCC survival, revealing the broad clinical utility of MAPK pathway mutations in prognosis and potentially in precision immunotherapy.
A novel class of polymorphic toxins in BacteroidetesBacteria often use toxins to mediate their interaction with the environment. This study reveals a new class of polymorphic toxins, which contain an N-terminal TANFOR domain, in Bacteroidetes.
