    Spatio-temporal control of mutualism in legumes helps spread symbiotic nitrogen fixation

    Benoit Daubech et al.
    Experiments and mathematical modelling show that rare nitrogen fixing symbionts invade a population dominated by non-fixing bacteria across plant generations, above a threshold of a combination of ecological factors.

    A plant chitinase controls cortical infection thread progression and nitrogen-fixing symbiosis

    Anna Malolepszy et al.
    Lotus japonicus chitinase modulates the level of rhizobial Nod factor and thereby enables cortical infection and functional symbiosis in root nodules.
