“…In the present study, night warming significantly decreased Zn concentrations in plant shoots, but R. irregularis enhanced plant Zn uptake under night warming. A recent meta-analysis of AM fungal functions in crop Zn nutrition also supports an important role of AM fungi in Zn nutrition under distinct environmental conditions (Lehmann et al 2014). Therefore, the extent to which climatic changes affect plant physiology, especially nutrition acquisition, could be modified by the plant symbiotic status.…”

Elevated night temperature, one of the main climate warming scenarios, can have profound effects on plant growth and metabolism. However, little attention has been paid to the potential role of mycorrhizal associations in plant responses to night warming, although it is well known that symbiotic fungi can protect host plants against various environmental stresses. In the present study, physiological traits of Medicago truncatula L. in association with the arbuscular mycorrhizal (AM) fungus Rhizophagus irregularis were investigated under simulated night warming. A constant increase in night temperature of 1.53°C significantly reduced plant shoot and root biomass, flower and seed number, leaf sugar concentration, and shoot Zn and root P concentrations. However, the AM association essentially mitigated these negative effects of night warming by improving plant growth, especially through increased root biomass, root to shoot ratio, and shoot Zn and root P concentrations. A significant interaction was observed between R. irregularis inoculation and night warming in influencing both root sucrose concentration and expression of sucrose synthase (SusS) genes, suggesting that AM symbiosis and increased night temperature jointly regulated plant sugar metabolism. Night warming stimulated AM fungal colonization but did not influence arbuscule abundance, symbiosis-related plant or fungal gene expression, or growth of extraradical mycelium, indicating little effect of night warming on the development or functioning of AM symbiosis. These findings highlight the importance of mycorrhizal symbiosis in assisting plant resilience to climate warming.

“…As far as AMF symbiosis is concerned, the metabolite mobilization and metabolism in crops and other plants has been a subject of interest for many workers (Van der Heijden et al, 2006;Smith and Smith, 2011;Smith and Smith, 2012;Lehmann et al, 2014;Rillig et al, 2014). Though there is sizable amount of referral material available on various such studies yet there seems to be none available on the modified or storage underground stem systems.…”

Arbuscular Mycorrhizal Fungi (AMF) have mutualistic relationships with more than 80% of terrestrial plant species. Arbuscular mycorrhizal fungal symbiosis have remarkable role in sustainable growth and development of plants as they help the land plants to acclimatize the biotic and abiotic conditions for their better survival, growth and development. In the present study surface sterilized tubers and seeds of potato were sown in earthen pots filled with sterile soil. Half the pots were inoculated with sterilized 30 AMF spores of the Glomus intraradices and G. mosseae and 10 g of maize root inoculated with the species of G. intraradices and G. mosseae. Another half represented controls with no AMF inoculation. Inoculation was done twice 3 days before sowing the tubers and seeds and on the onset of germination. Potted plants were regularly watered. After seedling emergence, the inoculated plants along with their controls were sampled at 20, 40, 60 and 80 days of growth. The observed data seems to predict that there is a net increase in the above and below ground growth of the plant with each 20 days interval after seedling emergence. The present study seems interesting since it pertains the work on modified stem vis a vis mycorrhizal relationship of a modified stem than normal root. The Chlorophyll content besides morphological growth parameters and fresh and dry weight content of both cultivars of potato plant are shown to present in higher level in the mycorrhiza infected as compared to the non-inoculated ones.

“…AMF develop wide extraradical mycorrhizal network into rhizosphere of the host plant, which enlarges the root contacted areas of water and nutrient absorption in soil, but also stabilizes soil structure (Bedini et al, 2009). Therefore, AMF play a prominent role in nutrient uptake, including Zn, P, and Cu, from the soil to the fungal partner (Meier et al, 2012;Lehmann et al, 2014). Spraying high levels of Mg on leaves strongly inhibited root AM colonization and sporulation in sweet potato and onion grown in aeroponic and sand culture (Jarstfer et al, 1998), suggesting a negative correlation between Mg level and root AM colonization.…”
