    Pathogen effectors and plant immunity determine specialization of the blast fungus to rice subspecies

    Jingjing Liao et al.
    Specialized fungal pathogen populations infect rice varieties with contrasting immune systems co-cultivated in a traditional agro-system, indicating the relevance of crop diversity to restricting epidemics in the landscape.

    Regulation of rice root development by a retrotransposon acting as a microRNA sponge

    Jungnam Cho, Jerzy Paszkowski
    Retrotransposon-derived messenger RNA plays a critical role in rice root development via sequestration of miR171, which suggests a novel trans-acting regulation by transposable elements.

    Multiple abiotic stimuli are integrated in the regulation of rice gene expression under field conditions

    Anne Plessis et al.
    Simple mathematical models can relate gene expression to climatic variables in field grown rice.

    A viral protein promotes host SAMS1 activity and ethylene production for the benefit of virus infection

    Shanshan Zhao et al.
    Rice dwarf virus Pns11 protein increases rice susceptibility to virus infection by enhancing OsSAMS1 enzymatic activity and ethylene production.

    Transcriptome analysis illuminates the nature of the intracellular interaction in a vertebrate-algal symbiosis

    John A Burns et al.
    The endosymbiosis between an alga and the spotted salamander shows several parallels to invertebrate-algal symbioses as well as to pathogen associations in vertebrate animals.

    Origin and evolution of the nuclear auxin response system

    Sumanth K Mutte et al.
    The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.

    E3 ubiquitin ligase Bre1 couples sister chromatid cohesion establishment to DNA replication in Saccharomyces cerevisiae

    Wei Zhang et al.
    E3 ubiquitin ligase Bre1-induced H2B monoubiquitination is epigenetically important for recruiting replication factor Mcm10 and cohesion establishment factors Ctf4, Ctf18 and Eco1 to early replication origins to establish sister chromatid cohesion.

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

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

    Guanidine hydrochloride reactivates an ancient septin hetero-oligomer assembly pathway in budding yeast

    Courtney R Johnson et al.
    A naturally-occurring small molecule acts as a chemical chaperone in vivo to alter the folding of a budding yeast septin and promote an oligomerization pathway that was lost during evolution.

    Harbouring public good mutants within a pathogen population can increase both fitness and virulence

    Richard J Lindsay et al.
    Cooperation theory and a novel synthetic infection system provides a mechanistic understanding of why a seemingly successful disease management strategy can have devastating consequences for infected hosts.
