“…These microorganisms have been reported to benefit plants by producing growth promoting regulators (the nature of which is said to resemble gibberellin and auxin), vitamins, amino acids, polypeptides, antibacterial and antifungal substances that exert phytopathogen biocontrol and polymers especially exopolysaccharides that improve plant growth and productivity (Zaccaro De Mule et al 1999;Stirk et al 1996;Ordog and Pulz 1996;Gupta and Agarwal 1973).…”

Jatropha curcas, the energy plant has attained great attention in recent years because of its biodiesel production potential and medicinal value. This makes it imperative to search for techniques for its rapid propagation. Our research communication has shown for the first time direct organogenesis without callus formation from embryo culture of Jatropha. All previous reports embody callusing before further propagation and use of whole seeds. We also report the very economical protocol for J. curcas using cyanobacterial culture filtrate (Aulosira fertilissima) in place of chemical hormones giving this paper a cutting edge to in vitro propagation of J. curcas. The result showed that the number of days taken for shoots and root induction was quicker by adding the cyanobacterial filtrate and shoot and root length was comparatively higher than the other treatment with synthetic plant growth regulator. The same trend was found for chlorophyll a and b. No such report previously has ever focused on the use of cyanobacterial filtrate on in vitro germination of J. curcas embryo to regenerate plants at a faster rate. Ex vitro rooting is a new approach, which will reduce the time for regeneration still further, is an area that is being presently tried out.

“…These organisms play an important role in this system by providing a steady input of fixed nitrogen (Roger et al, 1986). Also, cyanobacteria have been assumed to produce growth promoting substances like hormones, vitamins, amino acids or many other components that enhances germination (Singh and Trehan, 1973;Grieco and Desrochers, 1978;Rodgers et al, 1979;Venkataraman, 1981;de Caire et al, 1997;de Mule et al, 1999;Godd et al, 1999;Omar, 2000). Most of the soil and aquatic microscopic algae are sensitive to insecticides due to the fact that algae are engaged in photosynthesis and that many insecticides interfere with this process.…”

In a trial to evaluate the impact of one of the commonly used insecticides in Egypt, a plot area cultivated with soybean was sprayed with endosulfan. Some of the biochemical criteria of the treated soybean and the biodiversity and biochemical activity of its companion cyanobacteria were compared with those of the untreated ones. The results revealed that endosulfan application caused inhibition in the attendance and biodiversity of the soil cyanobacteria found in the rhizosphere of the treated soybean, specially the filamentous species. The treated soil showed a highly significant inhibition in their ARA (acetylene-reducing activity) and exopolysaccharides. The biochemical analysis showed a high significant decrease in all the carbohydrate fractions as well as DNA and RNA contents of the treated soybean plants compared with the untreated ones. However, the total soluble proteins significantly Increased, indicating some defense pattern against the lethal effects of endosulfan. From the results, it could be concluded that application of endosulfan has a significant potential to change ecosystems and soil biological processes and could potentially reduce future farm productivity and cause harmful impact to agriculture.
