    Environmental DNA from archived leaves reveals widespread temporal turnover and biotic homogenization in forest arthropod communities

    Henrik Krehenwinkel, Sven Weber ... Michael Veith
    Environmental DNA from highly standardized leaf sample time series suggests no localized species losses, but biotic turnover and homogenization, as main drivers of forest insect decline.

    Environmental response in gene expression and DNA methylation reveals factors influencing the adaptive potential of Arabidopsis lyrata

    Tuomas Hämälä, Weixuan Ning ... Outi Savolainen
    Environmentally responsive genes evolve under strong selective constraint in Arabidopsis lyrata.

    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.

    Temperature sensitivity of the interspecific interaction strength of coastal marine fish communities

    Masayuki Ushio, Testuya Sado ... Masaki Miya
    Fish environmental DNA remaining in a cup of seawater provides information about interaction strengths among marine fish species in nature, highlighting the potential impact of global climate change on community dynamics and stability.

    Hyperosmotic stress memory in Arabidopsis is mediated by distinct epigenetically labile sites in the genome and is restricted in the male germline by DNA glycosylase activity

    Anjar Wibowo, Claude Becker ... Jose Gutierrez-Marcos
    Transient adaptation to environmental fluctuations in plants is mediated through discrete epigenetic changes.

    Mechanism of environmentally driven conformational changes that modulate H-NS DNA-bridging activity

    Ramon A van der Valk, Jocelyne Vreede ... Remus T Dame
    The DNA-bridging efficiency of H-NS, a genome organising and transcription regulatory protein, is modulated by changes in environmental conditions of the cell, which drive a structural rearrangement of the protein.

    Freshwater monitoring by nanopore sequencing

    Lara Urban, Andre Holzer ... Maximilian R Stammnitz
    From now on, nanopore metagenomics can be used to monitor aquatic environments with high spatiotemporal resolution, by use of a benchmarked, standardised and cost-effective workflow.

    Cell elongation is regulated through a central circuit of interacting transcription factors in the Arabidopsis hypocotyl

    Eunkyoo Oh, Jia-Ying Zhu ... Zhi-Yong Wang
    Signals from major hormones and the environment are integrated in the Arabidopsis hypocotyl to control gene expression and plant stem elongation.
