The first known species of rhizobia, Rhizobium leguminosarum, was identified in 1889, and all further species were initially placed in the Rhizobium genus. (wikipedia.org)
One of the things legumes are known for, particularly among agricultural circles, is the ability of many species to introduce nitrogen into soils-a vital ingredient for plant growth. (www.csiro.au)
At this point we should make clear that not all species of legumes are dependent on rhizobia. (www.csiro.au)
Medium pH ranging between 5.5 and 6.5 is ideal for rooting of most horticultural crops, although cuttings of some species prefer lower or higher pH. (globalsciencebooks.info)
Ants can be beneficial in the garden, but some species are straight up pests. (phytotheca.com)
In the narrowest sense of the term, as popularly used, symbiosis has been defined as the interactive association of two species in a mutually beneficial relationship. (newworldencyclopedia.org)
However, biologists define it according to the original, comprehensive concept of de Bary: the living together of members of two or more species in all the various forms, whether the interaction is beneficial, harmful, or neutral to one or both organisms. (newworldencyclopedia.org)
But some species are also able to establish a relationship with marine or terrestrial bacteria that can use nitrogen from the air: this is the biological nitrogen fixation. (encyclopedie-environnement.org)
The rhizosphere, which is the narrow zone of soil surrounding plant roots, can comprise up to 10 11 microbial cells per gram of root and above 30,000 prokaryotic species that, in general, improve plant productivity. (bio-fit.eu)

There are at least two reasons why this may be the case: 1) Non optimal soil conditions, and 2) Absence of the specific Rhizobium species or biovar needed for the forage crop in question. (oregonstate.edu)
Absence of the specific Rhizobium species or biovar needed for maximum infection and nodulation may occur if the forage crop being grown has not been grown in the soil for a number of years. (oregonstate.edu)
Furthermore, it has been determined that different forage legumes require different species or even different biovars within species of Rhizobium for successful formation of nodules. (oregonstate.edu)
For example, a Rhizobium species or biovar that will successfully nodulate alfalfa may not effectively inoculate some clovers. (oregonstate.edu)
To indicate which species or biovars of rhizobia effectively nodulate which legumes, scientists have developed so called 'cross inoculation groups. (oregonstate.edu)
The term 'Cross inoculation groups' refers to a classification scheme used to designate which groups of forage legumes are successfully inoculated by which species or biovars of rhizobia. (oregonstate.edu)
For example, the cross inoculation group for the species of rhizobia known as Rhizobium meliloti is alfalfa ( Medicago sativa ) and sweetclover ( Melilotus spp. (oregonstate.edu)
In the present review, molecular and physiological mechanisms explaining the observed beneficial effects plant derive from the Si supplementations, more particularly in horticultural species have been discussed. (researchsquare.com)

The legume-rhizobium symbiosis is a classic example of mutualism-rhizobia supply ammonia or amino acids to the plant and in return receive organic acids (principally as the dicarboxylic acids malate and succinate) as a carbon and energy source. (wikipedia.org)
Given the costs involved in nodulation and the opportunity for rhizobia to cheat, it may be surprising that this symbiosis should exist at all. (wikipedia.org)
So, it is a mutually beneficial relationship between legumes and rhizobia, something known in science as a type of symbiosis. (www.csiro.au)
Yan Liang and Gary Stacey research the symbiosis between legumes, like these soybeans, and nitrogen-fixing bacteria at the Bond Life Sciences Center. (missouri.edu)
This interesting symbiosis between clover and Rhizobium , can be disrupted by the plant pathogenic nematode Meloidogyne, more commonly known as the root-knot nematode . (wisc.edu)
The third category, the one of interest here, includes soil bacteria that live in symbiosis* with the root system of plants (see Symbiosis & parasitism ). (encyclopedie-environnement.org)
Figure 2) and Rhizobium-type bacteria that enter into symbiosis with plants of the legume family (Fabaceae) [1] . (encyclopedie-environnement.org)
The purpose of inoculation is to make sure that there is enough of the correct type of bacteria present in the soil so that a successful legume-bacterial symbiosis is established. (oregonstate.edu)

Scientists have wondered for years exactly how this mutually beneficial relationship works. (missouri.edu)

As a result of the nodulation process, after the harvest of the crop there are higher levels of soil nitrate, which can then be used by the next crop. (wikipedia.org)
Legumes, such as soybean, sense this signal - called a NOD factor since it triggers nodulation - and create the nodules where the bacteria fix atmospheric nitrogen into the soil. (missouri.edu)
Formation of the galls can interfere with root function (i.e., movement of water and nutrients to leaves and stems above ground) and can also interfere with proper nodulation by Rhizobium . (wisc.edu)
In response to the secretion of flavonoids* by the root (Figure 3), bacteria are attracted to it and synthesize lipo-chito-oligosaccharides*, called nod factors (for nodulation). (encyclopedie-environnement.org)
If the bacteria in the soil are not providing optimal, effective infection and nodulation (i.e. inoculation) in the forage legume being grown, human intervention in the form of inoculation is recommended. (oregonstate.edu)

Bacteria break down the chemicals and toxins that inhibit beneficial microbes. (ag-usa.net)
Some of the sugars are used for growth and some are exuded into soil by plant roots to support the microbes involved in nutrient acquisition. (ag-usa.net)
Not surprisingly, outcomes from such plant and soil microbiome studies have resulted in a paradigm shift away from single, specific soil microbes to a more holistic microbiome approach for enhancing crop productivity and the restoration of soil health. (pressbooks.pub)

Root-knot nematodes cause swollen, distorted roots that can interfere with movement of water and nutrients within a plant. (wisc.edu)
Many nematodes are beneficial, but root-knot nematode infects the roots of a variety of plants (including clover) causing damage. (wisc.edu)

These groups include a variety of non-symbiotic bacteria. (wikipedia.org)
Rhizobia are unique in that they are the only nitrogen-fixing bacteria living in a symbiotic relationship with legumes. (wikipedia.org)
Since all plants seem to respond to the NOD factor, scientists think this immunity suppression ability could be evolutionarily ancient and part of how rhizobia bacteria changed from foe to a symbiotic partner. (missouri.edu)
It is through the mutual recognition of the two partners (the plant and the bacteria) that the symbiotic process begins. (encyclopedie-environnement.org)
One possibility, is to become less reliant on synthetic nitrogen fertilizers for soil, and utilize symbiotic nitrogen-fixing bacteria as sources for plant nitrogen. (pressbooks.pub)

In small, bump-like nodules on roots in crops like soybeans and alfalfa, rhizobia bacteria thrive, receiving food from these plants and, in turn, producing the nitrogen that most plants need to grow green and healthy. (missouri.edu)

65. What is the term for the process by which bacteria convert atmospheric nitrogen into a form that plants can use? (answerscrib.com)

The catch is that rhizobia also use legumes to maintain their population and, in turn, convert the nitrogen that the plants need. (www.csiro.au)
Our work uniquely shows that all flowering plants, not just legumes, actually do recognize the chemical signal given off by rhizobia bacteria," said Gary Stacey , Bond LSC investigator and plant sciences professor at the College of Agriculture, Food and Natural Resources. (missouri.edu)
While several plants can be called shamrocks, the most common plant to be so-named is white clover ( Tifolium repens ). (wisc.edu)
Actually, the credit goes to the bacterium Rhizobium which colonizes the roots of clover (along with the roots of other plants in the pea family) and causes formation of nodules (swellings) on the roots. (wisc.edu)
In exchange for this ready supply of nitrogen, the clover plants provide Rhizobium with sugars (produced through photosynthesis) that it needs to grow and reproduce. (wisc.edu)
Thus plants with root-knot nematode often look stunted and discolored due to nutrient deficiencies caused by the presence of the pathogen. (wisc.edu)
You're not going to find a lot of four-leafed clover leaves on plants with root-knot. (wisc.edu)
Root is has great role for plant adaptation and productivity of the agricultural crops as well as other plants by exploiting the soil resource thus, important for plant growth and development or main growth factors. (oap-onlinejournals.org)

The bacteria that is most often used to inoculate forage crops is bacteria in the genus Rhizobium . (oregonstate.edu)

Those metabolic pathways were similar to a known nitrogen-fixing bacterium called rhizobium in soybeans, which people previously thought wasn't similar. (missouri.edu)

Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen. (wikipedia.org)
Once the legume dies, the nodule breaks down and releases the rhizobia back into the soil where they can live individually or reinfect a new legume host. (wikipedia.org)
Having this specific rhizobia present is beneficial to the legume, as the N2 fixation can increase crop yield. (wikipedia.org)
It's this trait that makes them a very handy crop to have as part of an agricultural rotation cycle, as other non-legume crops can benefit from the nitrogen that legumes have left behind in the soil. (www.csiro.au)
