“…It has been established that different genera of cyanobacteria and algae significantly accumulate and release a diverse group of phytohormones including auxins, gibberellins (GA), cytokinins (CKs), and ethylene (ET) that are involved in plants' growth and development (Stirk et al, 2002; Hussain and Hasnain, 2011; Gayathri et al, 2015). Phytohormones such as indole-3-acetic acid (IAA) and CKs, excreted by symbiotic cyanobacteria are consumed by the host plants during their growth and developmental processes (Hussain and Hasnain, 2010).…”

Cyanobacteria and algae having complex photosynthetic systems can channelize absorbed solar energy into other forms of energy for production of food and metabolites. In addition, they are promising biocatalysts and can be used in the field of “white biotechnology” for enhancing the sustainable production of food, metabolites, and green energy sources such as biodiesel. In this review, an endeavor has been made to uncover the significance of various metabolites like phenolics, phytoene/terpenoids, phytols, sterols, free fatty acids, photoprotective compounds (MAAs, scytonemin, carotenoids, polysaccharides, halogenated compounds, etc.), phytohormones, cyanotoxins, biocides (algaecides, herbicides, and insecticides) etc. Apart from this, the importance of these metabolites as antibiotics, immunosuppressant, anticancer, antiviral, anti-inflammatory agent has also been discussed. Metabolites obtained from cyanobacteria and algae have several biotechnological, industrial, pharmaceutical, and cosmetic uses which have also been discussed in this review along with the emerging technology of their harvesting for enhancing the production of compounds like bioethanol, biofuel etc. at commercial level. In later sections, we have discussed genetically modified organisms and metabolite production from them. We have also briefly discussed the concept of bioprocessing highlighting the functioning of companies engaged in metabolites production as well as their cost effectiveness and challenges that are being addressed by these companies.

“…There are many indole conjugates with indole‐3‐acetic acid (IAA) that have the highest level of biological activity (Ludwig‐Müller ). IAA is the natural auxin commonly observed in plants and green algae ( Chlorella and Scenedesmus ) as well as blue‐green algae ( Oscillatoria and Aphanothece ) (Stirk & Van Staden ; Mazur et al ; Stirk et al ; Tarakhovskaya et al ; Gayathri et al ). Indole‐3‐butyric acid (IBA) is the main endogenous auxin in Anabaena vaginicola F.E.…”

In the present research, the effect of indole-3-butyric acid (IBA) on the growth, and the production of some primary and secondary metabolites was studied in Nostoc linckia. In this respect, algae cultures were supplied with 0, 0.01, 0.1, 1, 10, and 100 μM IBA for 14 days. IBA at concentrations of 10 and 100 μM induced algal growth expressed as fresh weight in N. linckia. Treatment with IBA at all concentrations stimulated heterocyst formation. In addition, low concentrations of IBA (0.01, 0.1, and 1 μM) had a stimulatory effect on chlorophyll a and carotenoids accumulation. In contrast, higher concentrations of IBA induced the accumulation of phycocyanin, allophycocyanin, and phycoerythrin in the treated algae. In this case, IBA at the concentration of 10 μM was more effective. A significant decrease in protein content was observed in the algae treated by 0.01 μM IBA. All concentrations of IBA caused a decrease in sugar content, but lower concentrations were more effective. IBA application in all of the concentrations except 100 μM increased oligosaccharide-linked mycosporine-like amino acids (OS-MAAs) content. Lower concentrations had a more significant effect on increasing OS-MAAs content. However the concentrations of 10 and 100 μM IBA decreased scytonemin content. These results indicated the stimulatory impact of IBA on weight, heterocyst formation, and photosynthetic pigments in N. linckia. Fig. 6. The effect of different concentrations of IBA on oligosaccharide-linked mycosporine-like amino acids (OS-MAAs) and scytonemin contents of N. linckia after 14 days of cultivation. See the caption of Figure 1 for other information.

“…In general, explant type, culture conditions and plant growth regulator regimes must be defined for each genotype in order to develop the successful micropropagation protocol (Stephenson and Fahey, 2004;Marfori, 2010 andSaini et al, 2012) Application of saline water in agriculture requires deep understanding of law to overcome the negative effects of salinity. Tissue culture technique supplements with artificial tools to study the effect of salinity on plants under conditions and production of the range of plant species all over the world (Gayathri et al, 2015).…”

Micropropagation is the most important tool to propagate some important economic trees such as Moringa oleifera L. to examine the morphological reaction of in vitro grown plantlets on MS culture medium supplemented with different PGR (BA, IBA, NAA and Kinetin) and investigate the in vitro propagation ability under NaCl different concentrations (0, 1, 2, 4 and 8g/l). Adding two levels of Iron Oxide NPs (5 and 10mg/L) was used to mitigate the effect of salt stress on micropropagation of plants. The results showed that NaCl at different concentrations significantly reduced the in vitro recorded shoots and roots parameters (number of shootlets, shootlet length, rooting %, number and length of roots), chlorophyll content and carotenoids. Moreover, proline content was increased with increasing NaCl concentration in the culture medium. In addition, adding Iron Oxide NPs to culture medium showed positive effects on alleviating salt stress. This study aimed to evaluate the adverse effect of salt stress on Moringa oleifera L. micropropagation and the possibility of using Iron oxide NPs to overcome these effects.
