“…Tian et al (2013) showed that the Plukenetia volubilis plants colonized by G. versiforme increased guaiacol peroxidase (G-POD) and CAT activities, thus reducing the damage caused by ROS accumulation under drought. The Allium sativum plants colonized by G. fasciculatum had markedly higher leaf SOD and CAT and root POD activities under SWD, compared with the non-AMF colonized controls (Borde et al, 2012). Wu et al (2006) also reported that AMF significantly increased leaf POD and glutathione reductase activities and root ascorbate peroxidase activity in trifoliate orange seedlings exposed to SWD.…”

Arbuscular mycorrhizal fungi (AMF) can enhance tolerance of plants to soil water deficit, whereas morphological observations of reactive oxygen species and antioxidant enzyme system are poorly studied. The present study thereby evaluated temporal variations of the antioxidant enzyme system in citrus (Citrus tangerina) seedlings colonized by Glomus etunicatum and G. mosseae over a 12-day period of soil drying. Root colonization by G. etunicatum and G. mosseae decreased with soil drying days from 32.0 to 1.0% and 50.1 to 4.5% in 0-day to 12-day, respectively. Compared to the non-AM controls, the AMF colonized plants had significantly lower tissue (both leaves and roots) hydrogen peroxide (H 2 O 2 ) and superoxide anion radical (O 2•-) concentrations during soil water deficit, whereas 1.03-1.92, 1.25-1.84 and 1.18-1.69 times higher enzyme activity in superoxide dismutase, peroxidase (POD) and catalase. In situ leaf H 2 O 2 and root POD location also showed that AM seedlings had less leaf H 2 O 2 but higher root POD accumulation. Furthermore, significantly higher root infection and antioxidant enzymatic activities in plants colonized with G. mosseae expressed than with G. etunicatum during the soil drying. These results demonstrated that the AMs could confer greater tolerance of citrus seedlings to soil water deficit through an enhancement in their antioxidant enzyme defence system whilst an decrease level in H 2 O 2 and O 2•-.

“…Mycorrhizal plants contain higher concentrations of ascorbate and glutathione and harbour a greater activity of superoxide dismutase, catalase and ascorbate peroxidase than the corresponding non-mycorrhizal control plants (Wu et al 2010;Borde et al 2011;Latef and Chaoxing 2011). Since plants show this response to mycorrhization even before they are treated with high salt concentrations, one can suggest that colonisation of the roots by an AM fungus makes the plants more tolerant to high soil salinity and also to other osmotic stresses.…”

Abstract. Saline habitats cover a wide area of our planet and halophytes (plants growing naturally in saline soils) are increasingly used for human benefits. Beside their genetic and physiological adaptations to salt, complex ecological processes affect the salinity tolerance of halophytes. Hence, prokaryotes and fungi inhabiting roots and leaves can contribute significantly to plant performance. Members of the two prokaryotic domains Bacteria and Archaea, as well as of the fungal kingdom are known to be able to adapt to a range of changes in external osmolarity. Shifts in the microbial community composition with increasing soil salinity have been suggested and research in functional interactions between plants and micro-organisms contributing to salt stress tolerance is gaining interest. Among others, microbial biosynthesis of polymers, exopolysaccharides, phytohormones and phytohormones-degrading enzymes could be involved.

Arbuscular mycorrhizal inoculations change the growth and biochemical composition of the host plant and soil. Mycorrhizal root systems do augment the absorbing area of roots from 10 to 100 times thereby greatly improving the ability of the plants to utilize the soil resources. A pot experiment was conducted during the kharif seasons at Jaipur, Rajasthan, to find out the effects of three different indigenous AM fungi i.e. Glomus mosseae, Glomus fasciculatum and Gigaspora decipiens either single and in combination inoculation on biochemical and histochemical changes of Pearl millet (Pennisetum glaucum L.) grown under barren soil conditions. The AM fungus has shown to improve the tolerance of plant to drought stress. Experimental results showed that AM fungi treated plants improved their plants growths, biochemical and histochemical changes as compared to non-mycorrhizal treatments. The AM fungi inoculated plant was found to be attaining maximum plant biochemical and histochemical substances in Glomus mosseae (alone) and also Glomus mosseae + Glomus fasciculatum treatments.
