Abstract When wheat (Triticum aestivum L.) seedlings are co-cultivated with Nostoc sp. strain 2S9B in hydroponics, the cyanobacterium colonizes the endorhizosphere at low frequency. Mild sonication of the roots dramatically increased the number of cyanobacteria within the root tissue. The cyanobacteria penetrated the roots in the form of motile filaments (hormogonia), and once inside, they divided and transformed into aseriate packages, which showed nitrogenase activity. Cyanobacteria were…

Association of N2-fixing cyanobacteria with wheat (Triticum vulgare L.) roots
Two locally prevailing hetyerocystous cyanobacterial isolates, collected from alluvial clay soil and identified as Nostoc muscorum and Anabaena variabilis, were tested (either singly or mixed) for
In vitro creation of artificial nitrogen fixing Cyanobacterium (Nostoc muscorum) association with wheat
Using sonication technique and addition of 2,4 dichlorophenoxyacetic acid to wheat roots, increasing colonization of Nostoc muscorum on roots and enhancement of nitrogen fixation as novel
Deciphering the factors associated with the colonization of rice plants by cyanobacteria
It is illustrated that the colonization of cyanobacteria in the plant tissues is facilitated by increased elicitation of plant enzymes, leading to improved plant growth, nutrient mobilization, and enhanced plant fitness.
Analysing the colonisation of inoculated cyanobacteria in wheat plants using biochemical and molecular tools
This represents a first report on understanding hydrolytic enzyme-mediated colonisation of cyanobacteria on roots of wheat plants using plant growth parameters and DNA fingerprints, and significant correlation of plant parameters with nitrogen-fixing potential and growth attributes and fingerprints of Cyanobacteria from roots further illustrated the novelty of the results.
Nostoc, Microcoleus and Leptolyngbya inoculums are detrimental to the growth of wheat (Triticum aestivum L.) under salt stress
The results suggest that cyanobacterial inoculation may not be appropriate for establishing wheat in saline soils but that cyanOBacteria could be very useful for stabilising soils.
Growth and biochemical characterization of associations between cyanobionts and wheat seedlings in co-culturing experiments
The transverse sections of roots in the co-cultured seedlings revealed the presence of aseriate packets of cyanobionts below the root epidermis, and it can be hypothesized that these sugars and amino acids may serve as signal substances in the development of functional associations between the relevant cyanobions and the wheat seedlings.
Colonization of Wheat Roots (Triticum aestivum L.) by N2-fixing Cyanobacteria
The tight association of Nostoc muscorum with the roots of wheat seedling resulted in the accumulation of Chlorophyll a in wheat roots and also exhibited nitrogenase activity by the roots, which increased significantly the dry weight of seedlings plants.
How significant to plant N nutrition is the direct consumption of soil microbes by roots?
Uptake of soil microbes by wheat (Triticum aestivum) roots appears to take place in soil, and the importance of this process to terrestrial N cycling is probably minor in comparison with fluxes of other forms of soil inorganic and organic N.
Signalling in Cyanobacteria–Plant Symbioses
Cyanobacteria are a morphologically diverse and widespread group of phototrophic bacteria, many of which are capable of nitrogen fixation, which form symbioses with a wide range of eukaryotic hosts including fungi, diatoms, dinoflagellates, sponges, ascidians, corals and plants.

Prospects and challenges of application of microalgae in various areas of agriculture, including crop production, protection and natural resource management are focused on.


Colonization of wheat (Triticum vulgare L.) by N2‐fixing cyanobacteria: III. The role of a hormogonia‐promoting factor
SUMMARY Initial colonization of the roots of wheat plants by Nostoc 2S9B in liquid culture was by motile hormogonia, irrespective of whether co-culture was started using a cyanobacterial inoculum
Improved N2 fixation in 2,4-D treated wheat roots associated with Azospirillum lipoferum: Studies of colonization using reporter genes
Study on colonization of wheat roots using the SpBr17 nodG-lacZ gene fusion, which expressed the lacZ gene at the highest level, indicated the localization of bacteria on the young parts of roots as a thick coat.
Colonization of wheat (Triticum vulgare L.) by N2‐fixing cyanobacteria: II. An ultrastructural study
The technical feasibility of forming a novel association between a N2-fixing cyanobacterium and a cereal is demonstrated and cyanobacteria were found either as hormogonia, filaments or aseriate packages.
Colonization of wheat para‐nodules by the N2‐fixing cyanobacterium Nostoc sp. strain 2S9B
In plants treated with 2,4-D and co-cultivated with cyanobacteria in medium without combined nitrogen, the rate of acetylene reduction was three times that seen in untreated but colonized roots, and the nitrogen content of roots but not shoots was significantly increased.
Colonization of wheat Triticum vulgare L.) by N2-fixing cyanobacteria: I. A survey of soil cyanobacterial isolates forming associations with roots
Differences in nitrogenase activities of the free-living and associated cyanobacteria, together with the effects of added nitrate, indicate that nitrogenase activity may be influenced by the plant and/or its products.

Nitrogen fixation of Azorhizobium in artificially induced root para-nodules in wheat
Nodule-like structures(para-nodules) can be induced in wheat roots by low concentrations of plant growth hormone (2,4-D).Growth of nodulated wheat plants was not affected by 2,4-D treatment.

Nitrogenase activity (C2H2 reduction) was demonstrated in seedlings of wheat roots bearing para-nodules induced by 2,4-dichlorophenoxyacetic acid and inoculated with Azospirillum brasilense and it was shown that the energy source required for nitrogenase activity was supplied by the host plant.
Bacterial endophytes in agricultural crops
Historically, endophytic bacteria have been thought to be weakly virulent plant pathogens but have recently been discovered to have several beneficial effects on host plants, such as plant growth promotion and increased resistance against plant pathogens and parasites.
