  • The effect of dual inoculation with vesicular-arbuscular (VA) mycorrhizal fungi, Glomus mosseae, and Bradyrhizobium sp. R938 on the nitrogenase activity of peanut plant (Arachis hypogeae L. cv. Youngho) was studied in pot experiment. As a result of the dual inoculation with Glomus mosseae and Bradyrhizobium on peanut plant, nitrogenase activity was increased by 1.5 times compared with single inoculation with Bradyrhizobium sp. R938. After 69 days growth of peanut plant, the size of nodules was also increased due to the mycorrhizal infection. The mean fresh weight per nodule was 6.7 mg in treatment with the dual inoculation, which is the 1.5 times increase compared with single inoculation with Bradyrhizobium sp. R938. These results suggested that there might be a hormonal effect of VA mycorrhizal fungi in addition to the effect of increase in nitrogen fixing ability through the enhancement of nutrient absorption.

  • To evaluate potential of VA mycorrhizal fungi for promoting growth of nitrogen-fixing trees and efficiency of fungal inoculation in relation to soil fertility and dual inoculation with bacteria, Alnus firma was grown for six months in pots with steam-sterilized soil after inoculation with Glomus mosseae, and Robinia pseudoacacia was grown in the fumigated field after inoculation with native Glomus sp. and Gigaspora sp. In unfertilized Alnus plants, 27% increase in dry weight(or 18% in height) was observed by Glomus inoculation, while plants inoculated with both VA mycorrhiza and actinomycete(crushed nodule inoculum) showed synergistic effect of 83% dry weight increase over uninoculated plants. In fertilized Alnus plants, mycorrhizal inoculation alone or dual inoculation with actinomycete resulted in depression of height and dry weight of plants. In case of Robinia, dual inoculation stimulated height growth by 23% (or dry weight by 25%) over the control in unfertilized field, while 13% more height growth(or 21% more dry weight) was observed in fertilized field. It is concluded that VA mycorrhizae, especially Glomus mosseae, have a potential for growth enhancement in Alnus, that synergistic effect of dual inoculation(mycorrhiza + actinomycete) exists in both Alnus and Robinia, and that responses of these plants to VA mycorrhiza are more pronounced in unfertilized soil.

  • The soil organisms that develop beneficial Symbiotic relationships with plants roots and contribute to plant growth are mycorrhizal (AM) fungi. 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.

  • In this study, soil samples were collected from cultivated fields of 1-5 year old Korean ginseng in Geumsan, Korea. Spores of arbuscular mycorrhizal fungi were extracted from soils and identified using morphological characteristics and 18s rDNA sequences of the spores. Total 10 species of AMF were identified: Acaulospora longula, Archaeospora trappei, Glomus caledonium, Glomus etunicatum, Glomus intraradices, Glomus mosseae, Glomus sp., Paraglomus occultum, Paraglomus brasilianum, and Scutellospora heterogama. Relative abundance of spores of A. trappei were increased with increase of cultivation period of the ginseng. However, relative abundance of other species of AMF and Shannon diversity (H') of AMF were significantly decreased with the increase of cultivation periods of the ginseng.

  • The purpose of this study was to investigate effects of inoculation of arbuscular mycorrhizal fungi (AMF) on growth of Korean ginseng (Panax ginseng C. A. Mey.) seedlings. Five species of AMF (Glomus mosseae, Glomus intraradices, Glomus etunicatum, Acaulospora longula, Acaulospora trappei) were inoculated to ginseng seedlings at 60 days after ginseng seed germination. Dry weights, heights of the plants and chlorophyll fluorescence were measured at 120 days after inoculation of AMF. Dry weights and shoot heights were increased in seedlings inoculated with AMF compared to the controls without AMF. However, chlorophyll fluorescence of seedlings with AMF showed no significant difference compared to the control.

  • Mulberry Seedlings germinated and grown under green house conditions were inoculated with Glomus mosseae, Mosse and Trappe (a Kind of Vesicular arbuscular mycorrhizae) prior to outplanting into unsterilized soil. They were grown on phosphate deficient soil for 6 months after planting. Shoot length, stem diameter and leaf yield of the inoculated plants were found to be significantly greater than uninoculated ones. It was observed in foliar mineral content that the levels of N, P$_2$O$\sub$5/, CaO of the inoculated plants were higher but the level of MgO of the inoculated plants was lower than the uninoculated ones. In the mineral content of roots, it was observed that the level of P$_2$O$\sub$5/ was higher but the level of N was lower significantly in the inoculated plants than the uninoculated ones.

  • The genomic DNAs were extracted from roots of Glycine max and Sorghum bicolor, and compared with those from spores of two arbuscular mycorrhizal(AM) fungi, Glomus mosseae and Scutellospora heterogama. The partial small subunit(SSU) of ribosomal RNA genes were synthesized and amplified by polymerase chain reaction with the fungal specific primers, AM1 and NS31. By the recent molecular techniques, the presence of another AM fungal DNA were confirmed in the roots of two plants, and three sequences of rDNA fragments amplified were identified to be close to those of G. caledonium, G. fasiculatum and G. proliferum. The two AM fungi, both, were found to colonize at the cortical layers of plant roots collected in the fields, together.

  • In this study, eight soil samples were collected from organic and conventional farms in a central area of South Korea. Spore communities of arbuscular mycorrhizal fungi (AMF) and glomalin, a glycoprotein produced by AMF, were analyzed. Spores of Glomus clarum, G. etunicatum, G. mosseae, G. sp., Acaulospora longula, A. spinosa, Gigaspora margarita, and Paraglomus occultum were identified at the study sites, based on morphological and molecular characteristics. While Acaulospora longula was the most dominant species in soils at organic farms, Paraglomus occultum was the most dominant species in soils at conventional farms. Species diversity and species number in AMF communities found in soils from organic farms were significantly higher than in soils from conventional farms. Glomalin was also extracted from soil samples collected at organic and conventional farms and was analyzed using both Bradford and enzyme-linked immunosorbent assays. The glomalin content in soils from organic farms was significantly higher than in soils from conventional farms. These results indicate that agricultural practices significantly affect AMF abundance and community structure.
