    Phosphatidylcholines from Pieris brassicae eggs activate an immune response in Arabidopsis

    Elia Stahl, Théo Brillatz ... Philippe Reymond
    Plants detect the presence of phospholipids in eggs from a herbivorous insect and trigger innate immunity.

    Caterpillar-induced rice volatiles provide enemy-free space for the offspring of the brown planthopper

    Xiaoyun Hu, Shuangli Su ... Ted CJ Turlings
    The brown planthopper has evolved a highly adaptive oviposition strategy by exploiting caterpillar-induced plant volatiles that provide safe havens for its offspring.

    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst, Susan R Strickler ... Georg Jander
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    A conserved filamentous assembly underlies the structure of the meiotic chromosome axis

    Alan MV West, Scott C Rosenberg ... Kevin D Corbett
    Meiotic chromosome axis 'core' proteins from fungi, plants, and mammals form a conserved filament architecture, and use a common mechanism to recruit HORMAD proteins for meiotic recombination control.

    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.

    An evolutionarily young defense metabolite influences the root growth of plants via the ancient TOR signaling pathway

    Frederikke Gro Malinovsky, Marie-Louise F Thomsen ... Daniel J Kliebenstein
    Young defense metabolites are often believed to be solely outputs but evidence suggests that they can regulate ancient signaling pathways.

    Temporal network analysis identifies early physiological and transcriptomic indicators of mild drought in Brassica rapa

    Kathleen Greenham, Carmela Rosaria Guadagno ... C Robertson McClung
    Coupled physiology and gene expression, measured over a two-day time course, reveals specific time-of-day responses to the early stages of drought in Brassica rapa.

    Drought Stress: Into the fourth dimension

    David L Des Marais
    The influence of time on the drought response of Brassica rapa, an agriculturally important species of plant, has been clarified.

    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.

    Kinetics of the LOV domain of ZEITLUPE determine its circadian function in Arabidopsis

    Ashutosh Pudasaini, Jae Sung Shim ... Brian D Zoltowski
    In the plant circadian clock photoreceptor ZEITLUPE, evolutionarily selected residues distinguish photocycle kinetics and allosteric signal transduction pathways to permit proper circadian timing.
