Time lags in the regulation of symbiotic nitrogen fixation

New Phytologist, Volume 247, Issue 4, Page 1680-1693, August 2025.
Summary Theory has shown that time lags in the regulation of symbiotic nitrogen (N) fixation (SNF) can be important to the competitive dynamics and ecosystem consequences of N‐fixing trees, but measurements of these time lags are lacking. Here, we used a novel method to measure SNF in seedlings of four N‐fixing tree species that represent tropical and ...

Secretion systems and signal exchange between nitrogen-fixing rhizobia and legumes

Frontiers in Plant Science, 2015
The formation of symbiotic nitrogen-fixing nodules on the roots and/or stem of leguminous plants involves a complex signal exchange between both partners. Since many microorganisms are present in the soil, legumes and rhizobia must recognize and initiate

Functional and expression analysis of the metal-inducible dmeRF system from Rhizobium legumionosarum bv. viciae [PDF]

, 2013
A gene encoding a homolog to the cation diffusion facilitator protein DmeF from Cupriavidus metallidurans has been identified in the genome of Rhizobium leguminosarum UPM791. The R.

Impact of Plant Peptides on Symbiotic Nodule Development and Functioning

Frontiers in Plant Science, 2018
Ribosomally synthesized peptides have wide ranges of functions in plants being, for example, signal molecules, transporters, alkaloids, or antimicrobial agents. Legumes are an unprecedented rich source of peptides, which are used to control the symbiosis

Subtractive library of soybean roots in response to inoculation with Bradyrhizobium japonicum. [PDF]

, 2017
: Soybean [Glycine max (L.) Merr.] is the most important legume cropped worldwide, with an economic value attributed mainly to the high protein content of the grain, which, in turn, demands a heavy supply of nitrogen.

Gingival Stem Cell‐Conditioned Media and Low‐Level Laser Therapy Enhance Periodontal Ligament Stem Cells Function by Upregulating Wnt and TGF‐β Pathway Components: An In Vitro Study

Clinical and Experimental Dental Research, Volume 11, Issue 3, June 2025.
ABSTRACT Objectives This study investigated the synergistic effects of gingival stem cell conditioned media (GSC‐CM) and low‐level laser therapy (LLLT) on stimulating PDLSCs, explicitly focusing on the molecular basis of enhancing the Wnt and TGF‐β signaling pathways. Material and Methods PDLSCs were isolated and GSC‐CM were prepared and characterized.

Plant Hormones Differentially Control the Sub-Cellular Localization of Plasma Membrane Microdomains during the Early Stage of Soybean Nodulation [PDF]

, 2019
Phytohormones regulate the mutualistic symbiotic interaction between legumes and rhizobia, nitrogen-fixing soil bacteria, notably by controlling the formation of the infection thread in the root hair (RH).

MicroRNA gatekeepers: Orchestrating rhizospheric dynamics

Journal of Integrative Plant Biology, Volume 67, Issue 3, Page 845-876, March 2025.
MicroRNAs play a crucial role in plant communication within the rhizosphere, shaping growth, development, and resilience to biotic and abiotic stresses. ABSTRACT The rhizosphere plays a crucial role in plant growth and resilience to biotic and abiotic stresses, highlighting the complex communication between plants and their dynamic rhizosphere ...

Decoding small peptides: Regulators of plant growth and stress resilience

Journal of Integrative Plant Biology, Volume 67, Issue 3, Page 596-631, March 2025.
This review explores how small peptides act as key regulators of plant growth, development, and stress responses. It highlights recent advances in small peptide identification and their roles in enhancing plant resilience to environmental challenges, offering new perspectives for improving crop productivity.

A simple model based on known plant defence reactions is sufficient to explain most aspects of nodulation [PDF]

, 2017
We present the following hypothesis; that lipo-oligochitin Nod-factors can act in an elicitor-like fashion inducing, amongst other effects, a plant chitolytic enzyme, capable of hydrolysing the oligochitin chain of the Nod-factor.
