TL;DR: To realize the full potential of fungal SBCI it will be necessary to make advances in multiple areas, including changes to nomenclatural rules to enable validPUBLICation of sequence-based taxon descriptions.
Journal ArticleDOI
Failure to fix nitrogen by non-reproductive symbiotic rhizobia triggers host sanctions that reduce fitness of their reproductive clonemates.
TL;DR: It is demonstrated that even legume species that host non-reproductive bacteroids, specifically pea and alfalfa, can severely sanction undifferentiated rhizobia when bacteroids within the same nodule fail to fix N2.
Journal ArticleDOI
Comparing Symbiotic Efficiency between Swollen versus Nonswollen Rhizobial Bacteroids
Ryoko Oono,R. Ford Denison +1 more
TL;DR: Terminal bacteroid differentiation among legume species has evolved independently multiple times, perhaps due to the increased host fitness benefits observed in this study.
Journal ArticleDOI
Multiple evolutionary origins of legume traits leading to extreme rhizobial differentiation.
TL;DR: Analysis of the distribution of different bacteroid morphologies over a legume phylogeny to understand the evolutionary history of this host-influenced differentiation of rhizobia finds at least five independent origins of host traits leading to swollen bacteroids.
Journal ArticleDOI
Controlling the reproductive fate of rhizobia: how universal are legume sanctions?
TL;DR: Host sanctions can limit the evolutionary success of rhizobial cheaters (strains that would otherwise benefit by fixing less nitrogen), and the importance of sanctions to hosts and possible physiological mechanisms for sanctions may depend on whether bacteroids are potentially reproductive.
