    Evidence for suppression of immunity as a driver for genomic introgressions and host range expansion in races of Albugo candida, a generalist parasite

    Mark McMullan et al.
    Hybridization and introgression blur species boundaries and broaden genetic diversity available for adaptation; and widespread introgression underpins the evolution of races of the generalist pathogen Albugo candida that specialise on different host plant species.

    Crystallographic observation of nonenzymatic RNA primer extension

    Wen Zhang et al.
    Time resolved crystal structures reveal the binding of activated monomers to the template, followed by generation of the imidazolium-bridged dinucleotide intermediate, and finally formation of a phosphodiester bond between the primer and the adjacent monomer.
