Root nodule (RN) symbiosis has a unique feature in which symbiotic bacteria fix atmospheric nitrogen. The symbiosis is established with a limited species of land plants, including legumes. How RN symbiosis evolved is still a mystery, but recent findings on legumes genes that are necessary for RN symbiosis may give us a clue. 
Transcriptional networks leading to symbiotic nodule organogenesis.
TLDR
How the de novo assembly of transcriptional networks may account for the predisposition to nodulate is discussed. Expand
A transcription factor NIN is the executor of root nodule development
In order to confer symbiotic nitrogen fixation on non-legumes such as rice, it is crucial to identify symbiotic genes that are specific to legumes. We found that a transcription factor NIN, which isExpand
Nitrogen Systemic Signaling: From Symbiotic Nodulation to Root Acquisition.
Plant nutrient acquisition is tightly regulated by resource availability and metabolic needs, implying the existence of communication between roots and shoots to ensure their integration at theExpand
The Symbiosome: Legume and Rhizobia Co-evolution toward a Nitrogen-Fixing Organelle?
TLDR
The current understanding of the symbiosome suggests that it might be considered a nitrogen-fixing link in organelle evolution and that the distinct types of legume symbiosomes could represent different evolutionary stages toward the generation of a nitrogen -fixing organelle. Expand
Heart of Endosymbioses: Transcriptomics Reveals a Conserved Genetic Program among Arbuscular Mycorrhizal, Actinorhizal and Legume-Rhizobial Symbioses
TLDR
A comparative transcriptomics approach was used to identify genes involved in establishing these 3 endosymbioses and their functioning and confirmed the existence of this core set of genes in accordance with the proposed recycling of ancient AM genes for new functions related to nodulation in legumes and actinorhizal plants. Expand
The Implications of Polyploidy for the Evolution of Signalling in Rhizobial Nodulation Symbiosis
TLDR
Assessing the implications of polyploidy for nodulation enables predictions about possible outcomes and, while several challenges exist for studying the effects of polyPLoidy on nodulation signalling, testing of these predictions in a variety of study systems will yield insights into the evolutionary consequences. Expand
The Casuarina NIN gene is transcriptionally activated throughout Frankia root infection as well as in response to bacterial diffusible signals.
TLDR
The characterization of CgNIN, a NIN gene from the actinorhizal tree Casuarina glauca is reported, indicating that elements specifically required for nodulation include NIN and possibly related gene networks derived from the nitrate signalling pathways. Expand
The evolutionary events necessary for the emergence of symbiotic nitrogen fixation in legumes may involve a loss of nitrate responsiveness of the NIN transcription factor
TLDR
It is speculated that the loss of the nitrate-responsiveness of NIN may be one of the evolutionary events necessary for the emergence of symbiotic nitrogen fixation in legumes. Expand
NODULE INCEPTION Directly Targets NF-Y Subunit Genes to Regulate Essential Processes of Root Nodule Development in Lotus japonicus
TLDR
It is proposed that the evolution of root nodules in legume plants was associated with changes in the function of NIN, which has acquired functions that allow it to divert pathways involved in the regulation of cell division to root nodule organogenesis. Expand
Evolution of rhizobium symbiosis
TLDR
It is concluded that the rhizobium Nod factor perception mechanism is recruited from the widespread endomycorrhizal symbiosis, and first evidence that Parasponia indeed makes use of the same signaling cascade as found in legumes is provided. Expand

TLDR
During the Rhizobium-legume symbiosis, bacteria enter the cells of host plants and differentiate into nitrogen-fixing bacteroids, which determine whether bacteroids are terminally differentiated cells or not. Expand
Cytokinin: secret agent of symbiosis.
TLDR
It is proposed that cytokinin is the key differentiation signal for nodule organogenesis and a model in which cytokin in might also influence bacterial infection by controlling the expression of NIN (Nodule Inception) and other transcriptional regulators through mechanisms operating both locally and systemically.

TLDR
A new view of the evolution of nodule processes is suggested that an initial infection process not involving root hairs led to two branches of legume nodule development, one that subsequently led to further evolution. Expand
Novel paralogous gene families with potential function in legume nodules and seeds.
TLDR
Within the plant kingdom, legumes are unusual in their ability to form nitrogen-fixing nodules in symbiosis with certain bacteria in the family Rhizobiaceae, and large, novel families of genes probably evolved to function in nodulation are identified. Expand
The evolution of nodulation
TLDR
The phylogeny of nodulating plants is described and a comparison is made between several aspects of legume and actinorhizal nodulation and the relationship between nodule symbiosis and endomycorrhizal symbiosis is described. Expand

Long-distance signaling to control root nodule number.
TLDR
Genes encoding a CLAVATA1-like receptor-like kinase that mediates autoregulation of nodulation have been identified from several legumes, such as Lotus japonicus and soybean and other hypernodulation mutants that are regulated by shoot or root genotypes have been isolated. Expand

Nitrogen-fixing nodules on plants such as alfalfa, pea and vetch arise from the root inner cortex and grow via a persistent meristem and are defined as indeterminate. Expand
