Phylogenetic Perspectives on the Origins of Nodulation

open access: yesMolecular Plant-Microbe Interactions, 2011
Recent refinements to the phylogeny of rosid angiosperms support the conclusion that nodulation has evolved several times in the so-called N2-fixing clade (NFC), and provide dates for these origins.

Competitive Nodulation Blocking of cv. Afghanistan Pea Is Related to High Levels of Nodulation Factors Made by Some Strains of Rhizobium leguminosarum bv. viciae

open access: yesMolecular Plant-Microbe Interactions, 2002
Cultivar Afghanistan peas are resistant to nodulation by many strains of Rhizobium leguminosarum bv. viciae but are nodulated by strain TOM, which carries the host specificity gene nodX.

Soybean CEP6 Signaling Peptides Positively Regulate Nodulation

open access: yesAgronomy
Nodulation is the most efficient nitrate assimilation system in the ecosystem, while excessive fertilization has an increased nitrate inhibition effect; deciphering the nitrate signal transduction mechanism in the process is of the utmost importance.

Occurrence and diversity of stem nodulation in Aeschynomene and Sesbania legumes from wetlands of Madagascar

open access: yesScientific Reports
Legumes have the ability to establish a nitrogen-fixing symbiosis with soil rhizobia that they house in specific organs, the nodules. In most rhizobium-legume interactions, nodulation occurs on the root.

Molecular characterization of plant mutants defective in mycorrhiza formation [PDF]

open access: yes, 2011
Arbuscular mycorrhizas play a key role in plant growth by supporting the acquisition of mineral nutrients, especially phosphorus. Around 80 % of vascular plants exhibit this association.

Symbiotic nitrogen fixation enhancement due to magnetite nanoparticles [PDF]

open access: yes, 2011
Population pressure on food production motivates the search for new ways to increase the productivity of arable land, especially land rendered marginal by salinity or aridity.

The NMN Module Conducts Nodule Number Orchestra

open access: yesiScience, 2020
Legumes control nodule number through nodulation and autoregulation of nodulation (AON) pathways. Nodule Inception (NIN) is essential for rhizobial infection and nodule organogenesis in legumes. The GmNINa-miR172c-NNC1 (NMN) module, which consists of two

Variability of nodulation traits in Andean and Mesoamerican common bean gene pools [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2017
: The objective of this work was to evaluate the genotypic diversity for nodulation in common bean (Phaseolus vulgaris) genotypes of Andean and Mesoamerican gene pools present in the core collections of Embrapa, in Brazil. Evaluations were carried out in

Systemic regulation of soybean nodulation and nitrogen fixation by nitrogen via isoflavones

open access: yesFrontiers in Plant Science, 2022
Nitrogen (N) inhibits soybean (Glycine max L.) nodulation and N2 fixation. Isoflavones secreted by soybean roots can stimulate signal transduction for symbiotic nodules, thus playing a key role in root nodule development and N2 fixation. The relationship

The relation between root hair infection by Rhizobium and nodulation in Trifolium and Vicia [PDF]

open access: yes, 1962
The infection of the root hairs of young seedlings of twelve species of Trifolium and of Vicia hirsuta was examined. The amount of infection (numbers of hairs containing infection threads) at 2 weeks varied much between species of host and was less ...
