Genetic Dissection of Pea Nodulated Root Architecture and Early Rhizobial Partner Choice Across a Diverse 335-Line Panel

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

Stepwise evolution of the developmental and symbiotic functions of DELLA in land plants

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.

A single genetic innovation at the origin of plant terrestrialization

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

The demonstration of a single origin for nodule evolution, with nodule engineering in a non-nodulating species

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

Horizontal gene transfers and terpene metabolism drive plant-fungal interaction in Marchantia polymorpha

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

A novel pathosystem between Aeschynomene evenia and Aphanomyces euteiches reveals new immune components in quantitative legume root-rot resistance.

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.

Divergent roles of CPK28 in immune homeostasis across land plants

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.

Exploring fern pathosystems and immune receptors to bridge gaps in plant immunity

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.

EPP1 is an ancestral component of the plant Common SymbiosisPathway

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

A Controlled Test of Risk-Dependent Immune Investment in a Clonal Ant

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.

Nissolia brasiliensis as a non-nodulating model legume

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

Symbiotic diversification relies on an ancestral gene network in plants

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

Ectomycorrhizal symbiosis evolved independently and by convergent gene duplication in rosid lineages

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

Genome sequence of the cluster root forming white lupin

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