Cyanobacteria‐rice plant interactions were analyzed using a hydroponics experiment. The activity of plant defense and pathogenesis‐related enzymes, scanning electron microscopy, growth, nitrogen fixation (measured as ARA), and DNA fingerprinting assays proved useful in illustrating the nature of associations of cyanobacteria with rice plants. Microscopic analyses revealed the presence of short filaments and coiled masses of filaments of cyanobacteria near the epidermis and cortex of roots and… 
Influence of cyanobacterial inoculation on the culturable microbiome and growth of rice.
TLDR
It is illustrated that cyanobacterial inoculation can play significant roles in improving growth and metabolism of rice directly and interact with the beneficial members from the endophytic microbiome of rice seedlings synergistically.
Cyanobacterial and rhizobial inoculation modulates the plant physiological attributes and nodule microbial communities of chickpea
TLDR
The findings illustrate that the performance of the chickpea plants may be significantly modulated by the microbial communities in the nodule, which may contribute towards improved plant growth and metabolic activity of nodules.
Cyanobacteria is uniquely enriched in the roots of grain amaranths
TLDR
Cyanobacteria are uniquely enriched by grain amaranths, and the diversity in OTUs among the Cyanobacteria also significantly increased among samples from amaranth species compared to negative control.
A consortium of cyanobacteria and plant growth promoting rhizobacteria for wheat growth improvement in a hydroponic system
TLDR
The study results indicate that the consortium of the five isolates gave the best performance in terms of growth parameters and biofertilizers containing the consortia cyanobacteria and PGPR used in this study are recommended for improved growth of wheat plants.
Cyanobacterial inoculation in rice grown under flooded and SRI modes of cultivation elicits differential effects on plant growth and nutrient dynamics
TLDR
The benefits of both types of rice cultivation methods and the promise of cyanobacteria in improving nutrient availability, soil fertility, and crop productivity are illustrated with a savings of 60 kg N ha−1 season−1.
Plant-Microbe Interactions in the Rhizosphere: Mechanisms and Their Ecological Benefits
TLDR
Strategies for improving plant-microbe interactions require more efforts to gain better understanding of these interactions using molecular, bioinformatics and modelling tools.
Co-cultivation of cyanobacteria for raising nursery of chrysanthemum using a hydroponic system
TLDR
The present investigation aimed to utilize plant growth–promoting diazotrophic cyanobacteria as an option to raise the chrysanthemum varieties Pusa Aditya and Jaya in a nursery by co-culturing hydroponically, and found that co- Culturing treatments performed significantly better, as compared with BG11 medium alone.
Diversity and functional traits of culturable microbiome members, including cyanobacteria in the rice phyllosphere.
TLDR
The adaptability and functional traits of these culturable microbiome members suggest enormous diversity in the phyllosphere, including potential for plant growth promotion, which was also significantly influenced by the different methods of growing rice.
Cyanobacteria in plant health: Biological strategy against abiotic and biotic stresses
TLDR
Cyanobacteria are capable of producing a great diversity of different chemical compounds with great effectiveness, in addition to releasing various enzymes, competing for the rhizosphere space and activating plant defense responses by interacting with their roots, representing an effective strategy against bacteria, fungi, oomycetes, nematodes, and harmful insects in agriculture.
Microalgae as multi-functional options in modern agriculture: current trends, prospects and challenges.
TLDR
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 roots of rice (Oryza sativa) by symbiotic Nostoc strains.
TLDR
Under laboratory conditions, artificial associations were created between one-third of the screened symbiotic cyanobacteria and rice, and the agricultural potential for the association appears high since the cyanob bacteria adsorb tightly and fix more N2 than when free-living.
Physiological characterization and electron microscopic investigation of cyanobacteria associated with wheat rhizosphere
TLDR
The concentrated culture filtrates of three cyanobacterial strains — C. ghosei, H. intricatus and Nostoc sp.
Co-cultivation of N2-fixing cyanobacteria and some agriculturally important plants in liquid and sand cultures
TLDR
The effect of the N2-fixing cyanobacteria on the plants tested during the co-cultivation seems to be very specific and the kind of relations depends on both the strain and the plant species.
Cyanobacteria mediated plant growth promotion and bioprotection against Fusarium wilt in tomato
TLDR
The reduced disease severity coupled with improved plant growth/ yields, elicited by cyanobacterial treatments, illustrated the utility of such novel formulations in integrated pest and nutrient management strategies for Fusarium wilt challenged tomato crop.

TLDR
Sonication of roots proved to be an efficient way of amplifying the internal root colonization by cyanobacteria and can be suggested as a method for creating a model system in non-legume plant-microbe studies.
Cyanobacterial diversity in the rhizosphere of rice and its ecological significance
TLDR
This investigation was undertaken to characterize the abundance and genera-wise diversity of cyanobacteria in the rice rhizosphere and nitrogen-fixing ability of the isolated strains and identified promising cyanobacterial isolates from the Rhizosphere of rice.
Changes in Rice Allelopathy and Rhizosphere Microflora by Inhibiting Rice Phenylalanine Ammonia-lyase Gene Expression
TLDR
It is suggested that PAL functions as a positive regulator of rice allelopathic potential because there was less rhizospheric bacterial diversity associated with transgenic rice than with WT.
Colonization of wheat (Triticum vulgare L.) by N2‐fixing cyanobacteria: II. An ultrastructural study
TLDR
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.
Beneficial rhizobacteria from rice rhizosphere confers high protection against biotic and abiotic stress inducing systemic resistance in rice seedlings.
TLDR
Two strains able to induce systemic resistance against Xanthomonas campestris seem to work by different pathways, and BaC1-38 primed pathogenesis-related proteins (PRs) and this pathway was more effective, both improved chlorophyll index confirming the priming state of the plant.
Non-symbiotic nitrogen fixation in the rhizospheres of rice, maize and different tropical grasses
TLDR
Nitrogenase activity estimated in the rhizospheres of rice, maize and different tropical grasses grown under controlled laboratory conditions was shown to depend upon plant species and responded greatly to light intensity.
