The radiation of nodulated Chamaecrista species from the rainforest into more diverse habitats has been accompanied by a reduction in growth form and a shift from fixation threads to symbiosomes

P. A. Casaes, J. M. Ferreira dos Santos, V. C. Silva, M. F. K. Rhem, M. M. Teixeira Cota, S. de Faria, J. G. Rando, E. K. James, E. Gross

This study examines the evolution of nodule symbiosis in Chamaecrista species, finding that the shift from fixation threads to symbiosomes correlates with changes in growth form and habitat.

Aromatic amino acid biosynthesis by a Lotus Aldolase impacts root hair development and symbiotic associations

J. Montiel, E. K. James, I. Garcia-Soto, D. E. Reid, S. Napsucialy-Mendivil, J. G. Dubrovsky, L. Cardenas, J. Stougaard

This study shows that Aldolase1 in Lotus japonicus is essential for root hair development and symbiotic associations with AM fungi and rhizobia, with mutants showing altered morphology and reduced symbiosis.

Two shifts in evolutionary lability underlie independent gains and losses of root-nodule symbiosis in a single clade of plants

H. Kates, B. C. O'Meara, R. LaFrance, G. W. Stull, E. K. James, S. Liu, Q. Tan, T. Yi, J.-M. Ane, D. Conde, M. Kirst, D. E. Soltis, R. P. Guralnick, P. S. Soltis, R. A. Folk

The paper reconstructs the evolutionary history of root-nodule symbiosis in the nitrogen-fixing clade, identifying a two-step process involving shifts in evolutionary lability that explain multiple independent gains and losses of the trait.

The innovation of the symbiosome has enhanced the evolutionary stability of nitrogen fixation in legumes

S. M. de Faria, J. J. Ringelberg, E. Gross, E. J. Koenen, D. Cardoso, G. K. D. Ametsitsi, J. Akomatey, M. Maluk, N. Tak, H. S. Gehlot, K. M. Wright, N. Teaumroong, P. Songwattana, H. C. de Lima, Y. Prin, , E. K. James

The paper investigates the evolutionary stability of nodulation in legumes, finding that symbiosomes enhance stability compared to fixation thread nodules.

A promiscuity locus confers Lotus burttii nodulation with rhizobia from five different genera

M. Zarrabian, J. Montiel, N. Sandal, H. Jin, Y.-Y. Lin, V. Klingl, M. Marin, E. K. James, M. Parniske, J. Stougaard, S. U. Andersen

This study identifies a genetic locus in Lotus burttii that enables nodulation with rhizobia from five different genera, suggesting a general mechanism for host-range expansion.

Distinct signalling routes mediates intercellular and intracellular rhizobial infection in Lotus japonicus

J. Montiel, D. E. Reid, T. H. Gronbaek, C. M. Benfeldt, E. K. James, T. Ott, F. A. Ditengou, M. Nadzieja, S. Kelly, J. Stougaard

This study identifies distinct genetic and transcriptomic requirements for intercellular rhizobial infection in Lotus japonicus compared to intracellular infection.
