Inhibition of legume nodulation by Pi deficiency is dependent on the autoregulation of nodulation (AON) pathway

The Plant Journal, 2020
SUMMARYInhibition of nodule development is one of the main adverse effects of phosphate (Pi) deficiency in legumes. Despite all of the efforts made over the last decades to understand how root nodules cope with Pi deficiency, the molecular mechanisms leading to the reduction in nodule number under Pi deficiency remain elusive.

Molecular Analysis of Legume Nodule Development and Autoregulation

Journal of Integrative Plant Biology, 2010
Abstract Legumes are highly important food, feed and biofuel crops. With few exceptions, they can enter into an intricate symbiotic relationship with specific soil bacteria called rhizobia. This interaction results in the formation of a new root organ called the nodule in which the rhizobia convert atmospheric nitrogen gas into forms of nitrogen that ...

Relationship between autoregulation and nitrate inhibition of nodulation in soybeans

Physiologia Plantarum, 1989
Ten of 11 supernodulating mutants of soybean [Glycine max (L.) Merr.] cv. Bragg, in which nodulation was far in excess of that in the wild type, showed pronounced tolerance of nodulation to applied nitrate. Mutant nts (nitrate‐tolerant symbiosis) 1116 had an intermediate nodulation response and also showed some inhibition by nitrate.

Autoregulation and Nitrate Inhibition of Nodule Formation in Soybean cv. Enrei and its Nodulation Mutants

Journal of Experimental Botany, 1993
The regulation and nitrate inhibition of nodule formation in soybean, Glycine max (L.) Merr., was further examined using the nodulation mutants of cv. Enrei. The non-nodulating mutants En 115, En 1282, and En 1314 produced extremely few markedly-curled root hairs which were all devoid of infection threads, and invariably failed to initiate sub ...

Autoregulation of Nodulation in Vicia sativa Ssp. NIGRA

1998
Leguminous plants such as pea and vetch (Vicia sativa ssp. nigra) are able to control the number of Rhizobium-induced root nodules per plant. This property is called “autoregulation of nodulation”, and represents a feedback response to development of the first nodules.

Split-root study of autoregulation of nodulation in the model legume Lotus japonicus

Journal of Plant Research, 2008
We used a split-root system to determine the timing for induction of the autoregulation of nodulation (AUT) in Lotus japonicus (Regel) Larsen after inoculation with Mesorhizobium loti. The signal took at least five days for full induction of AUT and inhibition of infection thread formation.

Genes for Autoregulation of Nodulation

2014
The phenomenon in which developed nodules or nodule primordia suppress the emergence of further nodules in legumes is termed autoregulation of nodulation (AON) (Nutman in Ann Bot 16:79–101, 1952). AON consists of two presumptive long-distance signal molecules involving roots and shoots (Caetano-Anolles and Gresshoff in Annu Rev Microbiol 45:345–382 ...

Autoregulation of Nodulation and Root Development in the Model Legume Lotus japonicus

2023
The har1-1 mutant of Lotus japonicus line Gifu is characterised by increased nodulation and significantly inhibited root growth in the presence of its microsymbiont Mesorhizoboium loti (for example strain NZP2235). A sexual cross between the mutant and another L.

Autoregulation of nodulation (AON) in Pisum sativum (pea) involves signalling events associated with both nodule primordia development and nitrogen fixation

Journal of Plant Physiology, 2009
To define the signalling events required for the activation of AON, we utilised approach grafts between wild-type pea plants and their mutants defective at successive stages of nodule formation. AON signalling strength was monitored by prior inoculation of mutant root portions (as so-called 'sensor') and quantifying nodule formation on connected roots ...

Heritability, signal perception and autoregulation of root nodulation in chickpea

Journal of Food Legumes
Chickpea (Cicer arietinum L.) establishes symbiotic interactions with Mesorhizobium to develop root nodules where nitrogen fixation occurs. This symbiotic relationship can fix atmospheric nitrogen (N2) up to 140 kg N/ha that contribute nearly 80% nitrogen requirement of the crop.
