Unraveling new molecular players involved in the autoregulation of nodulation in Medicago truncatula. [PDF]
J Exp Bot, 2019 The number of legume root nodules resulting from a symbiosis with rhizobia is tightly controlled by the plant. Certain members of the CLAVATA3/Embryo Surrounding Region (CLE) peptide family, specifically MtCLE12 and MtCLE13 in Medicago truncatula, act in

A Sinorhizobium meliloti-specific N-acyl homoserine lactone quorum-sensing signal increases nodule numbers in Medicago truncatula independent of autoregulation [PDF]
Frontiers in Plant Science, 2016 N-acyl homoserine lactones (AHLs) act as quorum sensing signals that regulate cell-density dependent behaviors in many gram-negative bacteria, in particular those important for plant-microbe interactions.

Simple and efficient methods to generate split roots and grafted plants useful for long-distance signaling studies in Medicago truncatula and other small plants [PDF]
Plant Methods, 2012 BACKGROUND: Long distance signaling is a common phenomenon in animal and plant development. In plants, lateral organs such as nodules and lateral roots are developmentally regulated by root-to-shoot and shoot-to-root long distance signaling. Grafting and

Peptide signaling at the intersection of growth, nutrient sensing, and stress responses. [PDF]
Plant JSUMMARY Plant endogenous peptides emerge as central regulators of multiple aspects of plant physiology. They are secreted from cells and perceived by plasma membrane localized receptors, which activate downstream signaling pathways to regulate growth and development. In addition, endogenous peptides coordinate physiology with their environment.

The Common Bean miR172c microRNA, a Relevant Regulator of the N-Fixing Symbiosis, Is Activated by SPL and AGL/MADS-Domain Transcription Factors. [PDF]
Physiol PlantABSTRACT Nitrogen‐fixing symbiosis (NFS) between rhizobia and legume plants is a complex and tightly regulated process. Modules of microRNAs (miRNAs) and their targets from different legumes, such as miR156‐SPL and miR172‐AP2‐1, form part of complex cascades relevant for the regulation of NFS.

A Comprehensive Transcriptome Atlas Reveals the Crucial Role of LncRNAs in Maintaining Nodulation Homeostasis in Soybean. [PDF]
Adv Sci (Weinh)Symbiotic nitrogen fixation promotes soybean growth, but maintaining energy balance is challenging. RNA‐seq of three organs of inoculated soybean identifies 88,814 mRNAs and 6,156 ncRNAs. Roots exhibit the most NR‐ncRNAs and dynamic crosstalk controlled by GmNARK.

Post-genomic insights into plant nodulation symbioses [PDF]
, 2003 Several legume genes involved in establishing nitrogen fixation have been discovered using functional genomics; when mutated, the genes affect symbioses, and all encode receptor kinases.
