    Host-selected mutations converging on a global regulator drive an adaptive leap towards symbiosis in bacteria

    M Sabrina Pankey et al.
    Selective forces imposed by the squid animal host drive rapid adaptation of non-native Vibrio fischeri bacteria through convergent mutations of large effect, unmasking preexisting coordinated regulation of symbiosis.

    In silico analysis of the transcriptional regulatory logic of neuronal identity specification throughout the C. elegans nervous system

    Lori Glenwinkel et al.
    Neuron type-specific gene batteries share cis-regulatory motifs.

    Phylogenomics of white-eyes, a ‘great speciator’, reveals Indonesian archipelago as the center of lineage diversity

    Chyi Yin Gwee et al.
    Contrary to the high absolute number of white-eyes in other parts of the world, the Indonesian archipelago is the center of phylogenetic diversity of this great speciator.

    Enteropathogen antibody dynamics and force of infection among children in low-resource settings

    Benjamin F Arnold et al.
    Among children in low-resource settings, diverse enteropathogens share common, population-level antibody dynamics, which creates a new opportunity to estimate transmission through serologic surveillance.

    Regulation of rice root development by a retrotransposon acting as a microRNA sponge

    Jungnam Cho, Jerzy Paszkowski
    Retrotransposon-derived messenger RNA plays a critical role in rice root development via sequestration of miR171, which suggests a novel trans-acting regulation by transposable elements.

    Repeated losses of PRDM9-directed recombination despite the conservation of PRDM9 across vertebrates

    Zachary Baker et al.
    PRDM9 is widely conserved across vertebrates yet has been lost numerous times, as has its role in directing meiotic recombination.

    LEAFY maintains apical stem cell activity during shoot development in the fern Ceratopteris richardii 

    Andrew RG Plackett et al.
    Transgenic analysis reveals a role for LEAFY in ferns that supports a trajectory from general to floral meristem-specific function as land plants evolved.

    Blumenols as shoot markers of root symbiosis with arbuscular mycorrhizal fungi

    Ming Wang et al.
    Arbuscular mycorrhizal fungi-induced hydroxy- and carboxyblumenol C glycosides accumulate in plant shoots and allow for facile high-throughput screening for functional plant-AMF associations.

    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.

    The kinase LYK5 is a major chitin receptor in Arabidopsis and forms a chitin-induced complex with related kinase CERK1

    Yangrong Cao et al.
    The chitin-triggered immune response is mediated by a LYK5 and CERK1 receptor complex in Arabidopsis.
