Water-tolerant nodulation is an adaptation of legumes that grow in wet or temporarily flooded habitats. This nodulation mode takes place at lateral root bases via intercellular bacterial invasion in cortical infection pockets. The tropical legume Sesbania rostrata has become a model for the study of the molecular basis of crack entry nodulation compared with root hair curl nodulation. For intercellular invasion, Nodulation Factor (NF) signalling recruits an ethylene-dependent, common Sym gene…

Nodule development on the tropical legume Sesbania virgata under flooded and non-flooded conditions.
TLDR
The interaction between the Brazilian pioneer legume Sesbania virgata and its microsymbiont Azorhizobium doebereinerae leads to the formation of nitrogen-fixing nodules on roots that grow either in well-aerated soils or in wetlands, which enables efficient nodulation in both dry and wet environments.
Exploring Legume-Rhizobia Symbiotic Models for Waterlogging Tolerance
TLDR
The mechanisms underlying symbiosis establishment, nodule development and functioning under waterlogging are summarized and the mechanisms of oxygen sensing of the host plant and symbiotic partner are considered in view of recent scientific advances.
Legume nodulation: The host controls the party.
TLDR
This review addresses recent findings in nodulation control, presents detailed models of the molecular mechanisms driving these processes, and identifies gaps in these processes that are not yet fully explained.
Rhizobium diversity in the light of evolution
Flooding tolerance of forage legumes
TLDR
Waterlogging and submergence tolerances of forage (pasture) legumes of tolerant species have higher root porosity (gas-filled volume in tissues) owing to aerenchyma formation and species also differ in tolerance of partial and complete shoot submergence.
Principales aspectos de la nodulación y fijación biológica de nitrógeno en Fabáceas
TLDR
The purposes of this review are to describe the infection mechanisms of rhizobia associated with Fabaceae known until now, to analyze the most important research works reported on nodule morphology and structure, and synthesize the most significant advances on nodulation in the three sub-families of Fabaceae.
Flooding and submersion-induced morphological and physiological adaptive strategies in Lonchocarpus cultratus
Root-knot Nematodes and Giant Cells
TLDR
The availability of new molecular technologies that enable detailed study of gene expression and regulation in giant cells, and new genomic technologies applied both to host and nematode pathogen, is leading to rapid advances in understanding host-pathogen interactions of this important plant pest species.
Evolutionary History Of The Angiosperm Npf1 Gene Subfamily: Duplications, Retention And Functional Implications For Root Symbioses And Development
TLDR
This dissertation proposes that LATD/NIP’s role in establishing nitrogen-fixing symbioses is derived from the ancient mycorrhizal signaling pathway, and uses a comparative phylogenomic approach to investigate the evolutionary origins of the NPF1 gene across flowering plants to resolve the evolutionary events that contributed two, novel genetic components for establishing root symbiosis.
Diversity of Interactions Between Rhizobia and Legumes
TLDR
Various interactions between rhizobia and legumes are reviewed and different infection patterns, nodule morphology and development and types of bacteroids in nodule cells are briefly discussed.

Switch from intracellular to intercellular invasion during water stress-tolerant legume nodulation.
TLDR
A comparison was made of the structural requirements for the perception of nodulation factors, which were more stringent for the epidermal root hair invasion than for the cortical intercellular invasion at lateral root bases.
Rhizobium infection: lessons from the versatile nodulation behaviour of water-tolerant legumes.
Gibberellins Are Involved in Nodulation of Sesbania rostrata1
TLDR
Results show that GAs are Nod factor downstream signals for nodulation in hydroponic growth and that they were also needed for nodule primordium development and inhibited the root hair curling process.
Reactive oxygen species and ethylene play a positive role in lateral root base nodulation of a semiaquatic legume
TLDR
Pharmacological experiments showed that ethylene and reactive oxygen species mediate Nod factor responses and are required for nodule initiation, whereby induction of division and infection could not be uncoupled.
Calcium Spiking in Plant Root Hairs Responding to Rhizobium Nodulation Signals
SrSymRK, a plant receptor essential for symbiosome formation.
TLDR
Evidence is provided that SymRK plays an essential role during endosymbiotic uptake in plant cells during symbiosis between legumes and rhizobia.
Rhizobium meliloti lipooligosaccharide nodulation factors: different structural requirements for bacterial entry into target root hair cells and induction of plant symbiotic developmental responses.
TLDR
Rhizobium meliloti produces lipochitooligosaccharide nodulation NodRm factors, which are clearly more stringent for bacterial entry than for the elicitation of developmental plant responses.
Ethylene Inhibits the Nod Factor Signal Transduction Pathway of Medicago truncatula
TLDR
Ethylene inhibited all of the early plant responses tested, including the initiation of calcium spiking, suggesting that ethylene acts upstream or at the point of calciumSpiking in the Nod factor signal transduction pathway, either directly or through feedback from ethylene effects on downstream events.
Roles for azorhizobial Nod factors and surface polysaccharides in intercellular invasion and nodule penetration, respectively
TLDR
To identify bacterial functions that are required for this infection process, two mutants defective in nodulation were studied and, in mixed inoculations with both mutants, functional nodules were formed, the central tissue of which was occupied by the nodA mutant.
Root nodulation of Sesbania rostrata
The tropical legume Sesbania rostrata can be nodulated by Azorhizobium caulinodans on both its stem and its root system. Here we investigate in detail the process of root nodulation and show that…
