“…In present study, N, P and K were significantly higher in leaves and roots of water stress mycorrhizal inoculated plants than those in uninoculated wheat plants. These findings are in concomitant with those of previous investigators who have reported that arbuscular mycorrhizal fungi absorb higher N and P than the control plants during drought stress (Miransari et al, 2008). Furthermore, the protection of the mycorrhizal plants against drought stress was related to the mycorrhizal induction of leaf conductance (Asrar and Elhindi, 2011) and transpiration (Auge, 2001) as well as P, N, and K uptake.…”

“…In general, colonization of plant roots by AM fungi is reduced when the temperature exceeds 30°C (Bowen 1987;, and often becomes lethal to AM fungi when temperature goes up to 40°C (Bendavid-Val et al 1997;Martin and Stutz 2004). On the other hand, mycorrhizal symbiosis may alter plant growth and physiology to allow it to cope with adverse stress conditions (Miransari et al 2008). In majority of cases, high temperature stress has a negative impact on plant growth and biomass (Wahid et al 2007).…”

The purpose of this study was to investigate the effects of arbuscular mycorrhizal (AM) symbiosis on gas exchange, chlorophyll fluorescence, pigment concentration and water status of maize plants in pot culture under high temperature stress. Zea mays L. genotype Zhengdan 958 were cultivated in soil at 26/22°C for 6 weeks, and later subjected to 25, 35 and 40°C for 1 week. The plants inoculated with the AM fungus Glomus etunicatum were compared with the non-inoculated plants. The results showed that high temperature stress decreased the biomass of the maize plants. AM symbiosis markedly enhanced the net photosynthetic rate, stomatal conductance and transpiration rate in the maize leaves. Compared with the non-mycorrhizal plants, mycorrhizal plants had lower intercellular CO 2 concentration under 40°C stress. The maximal fluorescence, maximum quantum efficiency of PSII photochemistry and potential photochemical efficiency of mycorrhizal plants were significantly higher than corresponding non-mycorrhizal plants under high temperature stress. AM-inoculated plants had higher concentrations of chlorophyll a, chlorophyll b and carotenoid than non-inoculated plants. Furthermore, AM colonization increased water use efficiency, water holding capacity and relative water content. In conclusion, maize roots inoculated with AM fungus may protect the plants against high temperature stress by improving photosynthesis and water status. KeywordsArbuscular mycorrhiza .

“…AM symbiosis can alter plant physiology to allow it to cope with stressful conditions (Miransari et al 2008). Many researchers reported that AM fungi could affect plant growth (Anderson et al 1987;Volkmar and Woodbury 1989), nutrition uptake and transport (Wang et al 2002;Hawkes et al 2008), metabolite content (Charest et al 1993;Paradis et al 1995).…”

The effect of arbuscular mycorrhizal (AM) fungus, Glomus etunicatum, on growth, water status, chlorophyll concentration and photosynthesis in maize (Zea mays L.) plants was investigated in pot culture under low temperature stress. The maize plants were placed in a sand and soil mixture at 25°C for 7 weeks, and then subjected to 5°C, 15°C and 25°C for 1 week. Low temperature stress decreased AM root colonization. AM symbiosis stimulated plant growth and had higher root dry weight at all temperature treatments. Mycorrhizal plants had better water status than corresponding non-mycorrhizal plants, and significant differences were found in water conservation (WC) and water use efficiency (WUE) regardless of temperature treatments. AM colonization increased the concentrations of chlorophyll a, chlorophyll b and chlorophyll a + b. The maximal fluorescence (Fm), maximum quantum efficiency of PSII primary photochemistry (Fv/Fm) and potential photochemical efficiency (Fv/Fo) were higher, but primary fluorescence (Fo) was lower in AM plants compared with non-AM plants. AM inoculation notably increased net photosynthetic rate (Pn) and transpiration rate (E) of maize plants. Mycorrhizal plants had higher stomatal conductance (g s ) than non-mycorrhizal plants with significant difference only at 5°C. Intercellular CO 2 concentration (Ci) was lower in mycorrhizal than that in nonmycorrhizal plants, especially under low temperature stress. The results indicated that AM symbiosis protect maize plants against low temperature stress through improving the water status and photosynthetic capacity.
