    Transgenesis and web resources in quail

    Olivier Serralbo et al.
    Transfection of quail primordial germ cells considerably expands the possibilities of genome modifications in birds, elevating the quail to the rank of genetic laboratory animal models of reference.

    The TRIM-NHL protein NHL-2 is a co-factor in the nuclear and somatic RNAi pathways in C. elegans

    Gregory M Davis et al.
    The RNA-binding protein NHL-2 is required for small-RNA mediated transgenerational epigenetic gene regulation.

    Conserved functional antagonism of CELF and MBNL proteins controls stem cell-specific alternative splicing in planarians

    Jordi Solana et al.
    A conserved alternative splicing program is specific to planarian stem cells and is controlled by the highly conserved splicing factors CELF and MBNL; therefore, this mode of regulating stem cells is likely ancestral to all animals.

    Cohesin and condensin extrude DNA loops in a cell cycle-dependent manner

    Stefan Golfier et al.
    Reconstitution of DNA loop extrusion in cellular contexts using Xenopus egg extracts shows that condensin extrudes DNA loops non-symmetrically in metaphase, whereas cohesin extrudes DNA loops symmetrically in interphase.

    Mammalian genes induce partially reprogrammed pluripotent stem cells in non-mammalian vertebrate and invertebrate species

    Ricardo Antonio Rosselló et al.
    Cells from vertebrate and invertebrate model systems can be reprogrammed into stem-like cells using mouse genes.

    Zygotic gene activation in the chicken occurs in two waves, the first involving only maternally derived genes

    Young Sun Hwang et al.
    In Aves, the first wave of transcription is derived exclusively from the maternal genome.

    Dynamics of primitive streak regression controls the fate of neuromesodermal progenitors in the chicken embryo

    Charlene Guillot et al.
    Inverse gradients of cell ingression and division in the epiblast allow the bipotent progenitors in the anterior streak to become the main progenitors for posterior axis formation from the tail bud.

    Characterization of the finch embryo supports evolutionary conservation of the naive stage of development in amniotes

    Siu-Shan Mak et al.
    Finch embryos are laid at an earlier stage than other avian embryos and contain cells with similar properties to pluripotent embryonic stem cells from mice.

    Codon optimization underpins generalist parasitism in fungi

    Thomas Badet et al.
    Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.

    An aging-independent replicative lifespan in a symmetrically dividing eukaryote

    Eric C Spivey et al.
    A high throughput, full lifespan microscopic analysis reveals that fission yeast does not age but has a finite replicative lifespan.
