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

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

This study analyzes the pangenome of Marchantia polymorpha to identify genetic features involved in plant adaptation to terrestrial environments, finding shared and lineage-specific genes with flowering plants.

The paper uses phylogenomic and phylotranscriptomic analyses to study the evolution of nitrogen-fixing root nodule symbiosis across the Nitrogen-Fixing Nodulation Clade, finding no convergence at the amino acid level and highlighting the role of NIN as a master regulator.

This study reconstructs the ancestral transcriptomic program for root-nodule nitrogen-fixing symbiosis by comparing transcriptomic responses across nine host plants, revealing most RNS novelties originated in a 110 million-year-old ancestor.

The paper identifies a cis-regulatory element, PACE, critical for bacterial uptake in plant cells through its role in nodule formation and infection thread development.

The paper shows remorin proteins stabilize membrane tubules and curvature during symbiotic infections in plants.

The paper investigates the evolutionary origin of lichenization in chlorophyte algae by analyzing genomes and transcriptomes of lichen algal symbionts and non-symbiotic algae, identifying convergent evolution and horizontal gene transfer as key factors.

This study identifies BSB, an ancestral strigolactone in bryophytes, which functions as a rhizosphere signal for AM symbiosis and was later co-opted as a plant hormone.

This study shows that rhizobia induce root morphological changes in Arabidopsis, regulated by nitrate signaling pathways involving NLP4, NLP5, and NRT1.1.

This study identifies SYFO1, a formin protein in Medicago truncatula, which connects the cell wall and cytoskeleton to facilitate rhizobial infection by enabling plasma membrane remodeling and cell polarization.

The paper shows that an ancestral signaling pathway is conserved in plant lineages with intracellular symbioses but lost in those with extracellular symbioses.

This study identifies the DREPP protein in Medicago truncatula and shows it regulates microtubule reorganization during rhizobial infection by localizing to membrane nanodomains.

The paper identifies plant lipid transfer to arbuscular mycorrhiza fungi, showing that fungal growth depends on lipid, not just sugar, from the host.
