    Combinations of maternal-specific repressive epigenetic marks in the endosperm control seed dormancy

    Hikaru Sato, Juan Santos-González, Claudia Köhler
    Analyses of cell type-specific data show that the maternal alleles of genes related to establishing and breaking seed dormancy are suppressed by different combinations of epigenetic marks in the endosperm of Arabidopsis.

    Flowering time and seed dormancy control use external coincidence to generate life history strategy

    Vicki Springthorpe, Steven Penfield
    Models of plant behaviour show that flowering early in a warming world is an adaptive strategy to insulate progeny seed behaviour from the affects of climate change.

    Dormancy-specific imprinting underlies maternal inheritance of seed dormancy in Arabidopsis thaliana

    Urszula Piskurewicz, Mayumi Iwasaki ... Luis Lopez-Molina
    A genomic imprinting program in the endosperm of Arabidopsis mature seeds is dynamically adjusted according to seed dormancy levels and regulates germination.

    Multiple alleles at a single locus control seed dormancy in Swedish Arabidopsis

    Envel Kerdaffrec, Danièle L Filiault ... Magnus Nordborg
    Natural variation for an adaptively important life history trait is largely due to variation at a single, major-effect locus with multiple alleles, demonstrating that not all complex traits are massively polygenic.

    Non-canonical RNA-directed DNA methylation participates in maternal and environmental control of seed dormancy

    Mayumi Iwasaki, Lena Hyvärinen ... Luis Lopez-Molina
    Seed-specific and cold-induced DNA methylation is deposited in the seed progeny to form a transient and transgenerational memory of past environmental conditions to optimize seed germination timing.

    The plant pathogen Pseudomonas aeruginosa triggers a DELLA-dependent seed germination arrest in Arabidopsis

    Hicham Chahtane, Thanise Nogueira Füller ... Luis Lopez-Molina
    Arabidopsis seed germination can be repressed by a Pseudomonas factor.

    Joint inference of evolutionary transitions to self-fertilization and demographic history using whole-genome sequences

    Stefan Strütt, Thibaut Sellinger ... Stefan Laurent
    Transitions from outcrossing to selfing, a major shift in mating systems, create a specific signature in intra-specific genetic polymorphisms, which can be used to infer the demographic history of populations and acquire valuable insights about the evolution of recombination rates.

    An ABA-GA bistable switch can account for natural variation in the variability of Arabidopsis seed germination time

    Katie Abley, Pau Formosa-Jordan ... James CW Locke
    Arabidopsis shows extensive genetic diversity in germination time distributions, which can be explained by the underlying ABA/GA network functioning as a noisy bistable switch.

    Philosophy of Biology: Characterizing causality in cancer

    Elena Rondeau, Nicolas Larmonier ... Andreas Bikfalvi
    Ideas about causality from philosophy can help scientists to better understand how cancerous tumors grow and spread in the body.

    A chloroplast retrograde signal, 3’-phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

    Wannarat Pornsiriwong, Gonzalo M Estavillo ... Barry J Pogson
    Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.
