Summary: Legume root nodule organogenesis is initiated by the stimulation of root cells and involves the regulation of specific gene families to promote cellular differentiation and auxin signaling. The emergence of nodules is dependent on a regulatory cascade involving NF-YA1, STY genes, and downstream targets YUCCA1 and YUCCA11. These genes are important regulators of auxin signaling during the specific stage of nodule emergence in Lotus japonicus and Medicago truncatula.

Summary: Forward and reverse genetics using model legumes have played a key role in identifying genes governing legume-rhizobia symbiosis. This study used QTL-seq to investigate the genetic basis of differential responses shown by Lotus accessions to inoculation with a specific mutant strain of Mesorhizobium loti, identifying Pxy as a key gene involved in the response.

Summary: Legumes balance nitrate signaling and symbiotic nitrogen fixation through cytokinin biosynthesis, with low nitrate conditions promoting cytokinin induction and high nitrate inhibiting it. This differential response is further seen in mutants, which show hypersensitivity to nitrate inhibition but can be rescued by cytokinin application. Nitrate's inhibitory effect on symbiosis occurs in a Nlp1 and Nlp4 dependent manner, contrasting with its positive influence on non-legumes.

Summary: This study aimed to explore and update LysM-RLKs in Lotus japonicus and propose a new classification to indicate their evolution and characteristics, as well as to predict new functions. We also found a strong correlation between the types of receptors in plant species and their symbiosis with arbuscular mycorrhizal fungi.

Summary: This study demonstrates the crucial role of the regulation of aromatic amino acid biosynthesis in sustaining root hair growth and establishing symbiotic relationships in the legume Lotus japonicus. The enzyme DAHPS1 is found to be critical for root hair development and for the symbioses with both rhizobial and mycorrhizal microbes. Mutants lacking DAHPS1 show altered root hair morphology, reduced symbiotic interactions, and downregulation of cell wall-related genes.

Summary: This study reports intercellular infection of the model legume Lotus japonicus by the IRBG74 strain and reveals the genetic requirements and differences in the pathways governing this process compared to intracellular infection. The results indicate a differential requirement for cytokinin signaling during intercellular rhizobial entry, highlighting distinct modalities of inter- and intracellular infection mechanisms in L. japonicus.
