    Natural haplotypes of FLM non-coding sequences fine-tune flowering time in ambient spring temperatures in Arabidopsis

    Ulrich Lutz, Thomas Nussbaumer ... Claus Schwechheimer
    Gene expression changes associated with polymorphisms in non-coding sequences of the flowering time regulator FLM directly influence flowering time in ambient temperature in Arabidopsis over an extended vegetative period.

    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.

    Drought adaptation in Arabidopsis thaliana by extensive genetic loss-of-function

    J Grey Monroe, Tyler Powell ... John K McKay
    Gene knockouts provide valuable genetic fuel for climate adaptation in nature.

    Seasonal shift in timing of vernalization as an adaptation to extreme winter

    Susan Duncan, Svante Holm ... Caroline Dean
    An adaptation to extreme winter has involved a shift to autumn temperature monitoring.

    m6A modification of U6 snRNA modulates usage of two major classes of pre-mRNA 5’ splice site

    Matthew T Parker, Beth K Soanes ... Gordon G Simpson
    High throughput sequencing of Arabidopsis mutants lacking the U6 snRNA methyltransferase FIONA1/METTL16 uncovers the role of U6 methylation in splicing signal preferences.

    Vernalization-triggered expression of the antisense transcript COOLAIR is mediated by CBF genes

    Myeongjune Jeon, Goowon Jeong ... Ilha Lee
    CBFs, the central regulators of low-temperature signaling, have a function to directly activate the expression of COOLAIR, an antisense RNA of FLC, during vernalization process, but COOLAIR is not required for the vernalization response.

    The Arabidopsis thaliana mobilome and its impact at the species level

    Leandro Quadrana, Amanda Bortolini Silveira ... Vincent Colot
    Population genomics in Arabidopsis thaliana uncovers an extensive repertoire of active transposable element families at the species level and reveals their importance as a source of rare alleles with large effects.

    The circadian clock controls temporal and spatial patterns of floral development in sunflower

    Carine M Marshall, Veronica L Thompson ... Stacey L Harmer
    The circadian clock acts with light response pathways to tightly synchronize daily rhythms in maturation of hundreds of florets in sunflower, promoting timely visits by pollinators and creating ring-like patterns on developing heads.

    A florigen paralog is required for short-day vernalization in a pooid grass

    Daniel Woods, Yinxin Dong ... Richard Amasino
    In Brachypodiumdistachyon, a single locus accounts for natural variation in whether perception of short day-lengths confers competence to flower.

    Global warming reduces leaf-out and flowering synchrony among individuals

    Constantin M Zohner, Lidong Mo, Susanne S Renner
    Individuals differ in how their leaf-out and flowering are regulated by abiotic stimuli and, under climate warming, this leads to reduced within-population phenological synchrony, impacting mutualistic and antagonistic community interactions.
