“…These micro-organisms play a valuable role in enhancing the growth of higher plants (ElAyouty, 1998). Cyanobacteria have been reported to benefit plants by producing growth-promoting regulators (the nature of which is said to resemble gibberellins and auxins), vitamins, amino acids, polypeptides, antibacterial and antifungal substances (Karthikeyan et al, 2007).…”

A field experiment was conducted during 2011 and 2012 seasons to evaluate the effect of cyanobacterial foliar application with different levels of chemical fertilizers (25%, 50% and 100% of the recommended dose of NPK fertilizer) on the growth characters, macro-elements content, essential oil percentage, yield and composition, total phenol content, total flavonoid content as well as the antioxidant activity of marjoram (Origanum majorana L.) plant. The cyanobacteria (Blue green algae) belonging to the strain Spirulina platensis were used as a foliar spray at four concentrations (0, 4.5, 7.5 and 10 g/l). The obtained results revealed that the application of cyanobacteria combined with 50 or 100% of the recommended dose of NPK fertilizer improved growth characters, chemical constituents and essential oil composition than the other treatments. So, using cyanobacterial foliar spray with 50% of the recommended dose of NPK fertilizer could provide a high quality product with reduced harmful agrochemicals and eliminate environmental pollution.

“…Despite availability of preliminary reports on associations between wheat roots and free-living cyanobacteria (Gantar et al1995), information on characterization of associations with symbiotic forms is scanty. Preliminary investigations under controlled conditions from our laboratory have shown that cyanobacteria co-cultured with wheat bring about significant enhancement in soil microbiological and plant parameters (Karthikeyan et al 2007;Jaiswal et al 2008).…”

N2-fixing cyanobacteria are unique in their capacity to form symbiotic associations with a wide range of eukaryotic hosts belonging to different plant groups. The present study was undertaken to analyze the interactions of the cyanobiont PI 01 (from Azolla pinnata) and Nostoc PCC 9229 (from Gunnera monoika) with wheat seedlings, in co-culturing experiments. Each of the cyanobionts enhanced significantly the volume of root and shoot biomass in the experimental cultures. The transverse sections of roots in the co-cultured seedlings revealed the presence of aseriate packets of cyanobionts below the root epidermis. The investigated cyanobionts excreted amino acids (His, Met, Val) and sugars into the medium, while indoleacetic acid was detected when the cyanobionts were grown in a tryptophan containing medium. During the co-culturing, sugars and proline were detected in the extracellular filtrates. It can be hypothesized that these sugars and amino acids may serve as signal substances in the development of functional associations between the relevant cyanobionts and the wheat seedlings.
