    Wild cereal grain consumption among Early Holocene foragers of the Balkans predates the arrival of agriculture

    Emanuela Cristiani, Anita Radini ... Dušan Borić
    A consistent pattern of consumption of Triticeae tribe grasses documented in the Danube Gorges of the Balkans since the Early Mesolithic might have facilitated a quick uptake of domesticated cereals due to a developed cultural taste and specific stone tool processing technology.

    Two NLR immune receptors acquired high-affinity binding to a fungal effector through convergent evolution of their integrated domain

    Aleksandra Białas, Thorsten Langner ... Sophien Kamoun
    The HMA domains of Pikp-1 and Pikm-1 NLR receptors have convergently evolved to bind AVR-PikD with high affinity through distinct evolutionary and biochemical paths.

    Windborne migration amplifies insect-mediated pollination services

    Huiru Jia et al.
    Delineating Episyrphus balteatus transregional movements and pollination networks advance a deep understanding of its migration ecology and facilitate the design of targeted strategies to conserve and enhance its ecosystem services.

    Eco-evolutionary dynamics modulate plant responses to global change depending on plant diversity and species identity

    Peter Dietrich, Jens Schumacher ... Christiane Roscher
    Offspring of plants selected at low and high plant diversity differently respond to global change drivers (nitrogen enrichment, drought), as reflected by their biomass production and trait expression, whereby plant-soil interactions play a significant role in these processes.

    The evolution of transposable elements in Brachypodium distachyon is governed by purifying selection, while neutral and adaptive processes play a minor role

    Robert Horvath, Nikolaos Minadakis ... Anne C Roulin
    Disentangling the different selective forces shaping the evolutionary dynamics of transposable elements (TEs) in the wild grass Brachypodium distachyon.

    Multiple kinases inhibit origin licensing and helicase activation to ensure reductive cell division during meiosis

    David V Phizicky, Luke E Berchowitz, Stephen P Bell
    Meiotic cells inhibit two distinct steps of replisome assembly with multiple kinases to prevent DNA replication between Meiosis I and Meiosis II.

    Optogenetic activation of heterotrimeric G-proteins by LOV2GIVe, a rationally engineered modular protein

    Mikel Garcia-Marcos, Kshitij Parag-Sharma ... Lien T Nguyen
    LOV2GIVe allows to activate Gi proteins non-invasively with innocuous blue light based on a design principle unrelated to light-activated GPCRs (metazoan opsins), thereby expanding the range of potential experimental applications.

    Ait1 regulates TORC1 signaling and localization in budding yeast

    Ryan L Wallace, Eric Lu ... Andrew P Capaldi
    The budding yeast gained a novel regulator of TORC1 signaling, called Ait1, 150–200 million years ago, around the same time they lost functional Rheb and Tsc1/2.
