This study identifies genetic factors influencing nodulated root architecture and rhizobial partner choice in pea using GWAS across 335 accessions.

The paper investigates the evolutionary conservation of DELLA protein functions in liverworts and finds GA-independent developmental roles are conserved, but DELLA is not involved in mycorrhizal symbiosis.

This study identifies a single genetic innovation, p-GPATs, as critical for the evolution of the plant cuticle and Arbuscular Mycorrhizal symbiosis during terrestrialization.

This study shows that nodule development can be engineered in non-nodulating species by restoring NIN functionality, supporting a single origin for nodulation.

This study identifies horizontally transferred terpene synthase genes and immune pathways in M. polymorpha that contribute to resistance against fungal pathogens.

This study uses Aeschynomene evenia to identify immune components involved in quantitative resistance to Aphanomyces euteiches, revealing dual-function kinases that regulate both symbiosis and immunity.

This study investigates the conserved and divergent roles of CPK28 in immune homeostasis across land plants, showing functional conservation in some contexts but divergence in others.

This study investigates fern-pathogen interactions and immune receptor diversity, revealing broad pathogen compatibility in Pteris vittata and identifying novel immune receptor classes in ferns.

The paper identifies EPP1 as a fourth gene in the ancestral common symbiosis pathway, essential for plant-microbe interactions across multiple plant clades.

The paper tests if high-risk social insect workers invest more in immune defenses but finds no evidence for risk-dependent immune investment in clonal ants.

This paper presents the first chromosome-level genome assembly of a non-nodulating legume, Nissolia brasiliensis, and identifies genes associated with root nodule symbiosis.

This study shows that LysM-RLKs in liverworts are involved in symbiosis and COs/LCOs perception, supporting their ancestral role in AM formation.

The paper identifies an ancestral gene network involved in intracellular symbiosis in plants, showing its conservation and convergent recruitment across different symbiotic systems.

The paper identifies 16 independent origins of ectomycorrhizal symbiosis in rosid lineages and finds convergent gene duplications in cell wall remodeling genes.

This study shows that the common symbiotic pathway genes are essential for arbuscular mycorrhizal symbiosis in bryophytes, indicating conservation of this pathway for 450 million years.

This study identifies MtAnn1 annexin as a key regulator of calcium signaling and cytoplasmic bridge formation during legume root infection by rhizobia.

The paper provides a high-quality genome sequence of white lupin and identifies a transcription factor regulating cluster root formation.
