Cucumis Melo L

Arbuscular mycorrhizal fungi (AMF) that can cause mutualism with higher plants. Some studies showed that the symbiosis of AMF will increase nutrients absorption, the capacity of anti-stress (e.g. drought, salt and disease) by melon (Cucumis melo L.). This study evaluated the roles of proteins on salt-tolerance mechanism after melon was symbiotic with AMF (Funneliformis mosseae). The melons were cultivated in the hydroponic solution containing 0 M, 0.042 M or 0.084 M NaCl for inoculated AMF and non-AMF inoculated seedlings. Root apice of AMF seedling after treating with different NaCl concentrations that were chosen for the estimation of proteins. The results showed that 12 proteins were significantly different after treating with different sodium chlorite (NaCl) concentrations, with proteins that four upregulated and eight downregulated. The tolerance of NaCl stress by root of melon that was inoculated by AMF were attributable to cellular activities involved in carbohydrate metabolism, energy metabolism, production of organic acid, relief of salt injury, which may be critical for promotion of nutrients absorption, anti-stress. This study can offer an important clue to advanced genomic exploration for the inoculation of AMF on different plants.

Gleditsia Sinensis

The Chinese honey locust tree Gleditsia sinensis Lam. (Fabaceae) is a precious ecological and economic tree species that has wide-ranging usage. However, knowledge regarding seedling cultivation (especially the use of arbuscular mycorrhizal fungi (AMF)) is scarce, which limits the developent of Gleditsia plantations. A pot experiment was carried out under greenhouse conditions to estimate the effects of three AMF strains (Funneliformis mosseae 1, Funneliformis mosseae 2, and Diversispora tortuosa) on the growth, photosynthetic rate, and nutrient content of G. sinensis seedlings. Results showed that the growth parameters (seedling height, basal diameter, dry biomass) of the seedlings were significantly increased by each of the three AMF strains, associated with high root colonization rates (greater than 75%). Chlorophyll concentrations and photosynthetic rates were also increased by AMF, and phosphorus (P), and potassium (K) content in the three organs (leaf, stem, and root), and nitrogen (N) content in the leaf and stem of arbuscular mycorrhizal (AM) seedlings were significantly higher than in non-AM seedlings. Mycorrhizal dependency of the AM seedlings was greater than 350%, and significantly correlated with the increased P and K content in all three organs and increased N content in the leaf and stem. Positive effects of F. mosseae on growth and the nutrient content of seedlings were higher than those of D. tortuosa, but no significant different effects on G. sinensis seedlings were observed between the two strains of F. mosseae. Hence, growth of G. sinensis seedlings was effectively enhanced by AMF, with F. mosseae being more suitable for the inoculation of G. sinensis seedlings. These results indicate that arbuscular mycorrhization is beneficial for the growth of young G. sinensis plants. Further research is needed to determine whether the effects can be reproduced in a forest situation.

Zelkova Serrata

Salinity is the primary restriction factor for vegetation conservation and the rehabilitation of coastal areas in Eastern China. Arbuscular mycorrhizal fungi (AMF) have been proved to have the ability to alleviate salt stress in plants. However, the role of AMF in relieving salt stress among indigenous trees species is less well known, limiting the application of AMF in the afforestation of local area. In this study, a salt-stress pot experiment was conducted to evaluate the effects of AMF on Zelkova serrata (Thunb.) Makino, a tree species with significant potential for afforestation of coastal area. The Z. serrata seedlings inoculated with three AMF strains (Funneliformis mosseae 1, Funneliformis mosseae 2, and Diversispora tortuosa) were subjected to two salt treatments (0 and 100 mM NaCl) under greenhouse conditions. The results showed that the three AMF strains had positive effects, to a certain extent, on plant growth and photosynthesis under normal condition. However, only F. mosseae 1 and F. mosseae 2 alleviated the inhibition of growth, photosynthesis, and nutrient uptake of Z. serrata seedlings under salt stress. The two AMF strains mitigated salt-induced adverse effects on seedlings mainly by increasing the leaf photosynthetic ability and biomass accumulation by reducing Na+ content, increasing P, K+, and Mg2+ content, as well as by enhancing photosynthetic pigments content and the stomatal conductance of leaves. These results indicated that AMF inoculation is a promising strategy for the afforestation of coastal areas in Eastern China.

Arbuscular mycorrhizal fungi (AMF) play an important role in Zn uptake by plants and can partially mitigate the effects of its deficit. On the other hand, they are involved in reducing the accumulation of Zn and its toxicity to plants when it is present in excessive concentrations in the soil. The aim of the study was to investigate the effect of two AMF, i.e., Funneliformis mosseae and Rhizophagus intraradices on Zn uptake by lettuce plants grown at two P levels and elevated concentrations of Zn in a peat substrate. The experiment demonstrated the effectiveness of mycorrhization of lettuce grown in the peat substrate; however, the arbuscular mycorrhiza did not reduce the uptake of Zn by lettuce. The AMF used in the experiment differentially affected the Zn content in lettuce. Compared to uninoculatedplants, R. intraradices increased the Zn content in lettuce, whereas F. mosseae did not affect the Zn content.

Arbuscular mycorrhizal fungi (AMF) are widely distributed in nature. They live in the roots of higher plants, in a symbiotic relationship. In this study, five commercial species of yams (Dioscoreaspp.) were inoculated with six species of AMF,Glomus clarum,G. etunicatum,G. fasciculatum,Gigasporasp.,G. mosseae, andAcaulosporasp., in field cultivation conditions to investigate the influence of AMF inoculation on tuber weights and secondary metabolite content in yam tubers. The results showed that mycorrhizae formation rates ranged from 63.33% to 90%.G. etunicatuminoculation treatment increased the tube weights of the five species of yam tubers by 39%, 35%, 20%, 56%, and 40% for Tainung 1, Tainung 2, Ercih, Zihyuxieshu, and Tainung 5, respectively. The content of secondary metabolites, such as polyphenols, flavonoids, and anthocyanin, was significantly increased by the AMF treatment in tuber flesh and peel of all the tested yam species. Specifically, the maximums exchange of secondary metabolite contents increased to 40%, 42%, and 106% for polyphenols, flavonoids, and anthocyanin, respectively, in the tuber fresh. This study revealed that different species of yam had varying degrees of affinity with various AMF species; selecting effective AMF species is necessary to facilitate yam growth and improve the quality and quantity of yam tubers.

Increasing yields in agriculture and management of soil fertility are becoming a major issue in view of the malnutrition problems. Tropical ferralitic soils are phosphorus (P)-deficient. The arbuscular mycorrhizal fungi (AMF) must form symbiotic associations with plants to enhance their hydro-mineral nutrition. The objective of this study was to evaluate the effect of mycorhization on growth of Vigna subterranea. Seedlings of two landraces were inoculated withAMF composite (Gigaspora margarita and Acaulospora tuberculata). P was administered by Hoagland solution (0 and 1000 mMPi). Two months after sowing, plants were harvested. The results show that,with or without phosphate, the number of nodules was three times (p less than 0.001) higher in mycorrhized plants compared to controls.Phosphate increased (p less than 0.001) the leaf P-content by 21 and 54% for the control and mycorrhized plants, respectively. Soluble phosphate did not affect the frequency and intensity of mycorhization. Soluble phosphate and mycorhizationsignificantly improve growth and leaf P-content.

Urban parks are ecosystems with a dynamic directed by human intervention. Arbuscular mycorrhizal fungi are symbionts with higher plants, with role in increasing the amount of nutrients needed to plant development. In roots, the fungi develops various structures for transfer or storage of nutrients. The grasses developed in the parks of the Cluj-Napoca city present typical mycorrhizal structures, including the two morphotypes of arbuscules. The colonization rate identified in the analyzed samples is over 75%, indicating a high number of propagules in soil. The dependence of arbuscles is higher to intensity than colonization frequency.
