Nodulating legumes are distinguished by a sensitivity to cytokinin in the root cortex leading to pseudonodule development

Gauthier-Coles, Christopher; White, Rosemary Gillian; Mathesius, Ulrike


Root nodule symbiosis (RNS) is a feature confined to a single clade of plants, the Fabids. Among Fabids capable of RNS, legumes form root cortex-based nodules in symbioses with rhizobia, while actinorhizal species form lateral root-based nodules with actinomycetes. Cytokinin has previously been shown to be sufficient for “pseudonodule” initiation in model legumes. Here, we tested whether this response correlates with the ability to nodulate across a range of plant species. We analyzed the...[Show more]
