  The present investigation was undertaken to find out efficient strains of arbuscular mycorrhiza (AM fungi) alone or in combinations with Trichoderma viride for inoculation Dendrocalamus strictus L. seedlings. The inoculated seedlings showed good response having higher plant height, phosphorous ions content in root and shoot, AM spore number and root colonization than non-inoculated (control) seedlings in both single (alone) and co-inoculation (combined consortium) experiments. T. viride showed significant growth followed by Glomus mosseae, G. fasciculatum and mixed AM with single inoculation. In co-inoculation, the best growth responses were observed with G. fasciculatum + T. viride followed by G. mosseae + T. viride, mixed vesicular arbuscular mycorrhizas (VAM) + T. viride, G. mosseae + G. fasciculatum + T. viride + mixed VAM, G. mosseae + G. fasciculatum + T. viride and G. mosseae + G. fasciculatum after 120 days and also depicted maximum increase in phosphorus content of shoot and root when compared with other inoculated seedlings. However, all the inoculated seedlings showed significant increase in phosphorus content when compared with control seedlings.

The growth of subterranean clover inoculated with two types of vesicular arbuscular endophytes was compared with that of uninoculated plants at five levels of applied superphosphate in a high phosphatefixing soil. Plants were grown in both untreated soil and soil steamed to eliminate the natural population of mycorrhizal fungi. Marked increases in the growth and phosphorus content of plants inoculated with a fungus isolated in Western Australia were apparent at intermediate levels of superphosphate in both soils. This fungus, which resembles Glomus mosseae (Nicol. & Gerd.) Gerd. & Trappe, was more efficient at increasing growth and phosphorus content of subterranean clover than Glomus fasciculatus (Thaxter) Gerd. & Trappe. The greater growth response of plants inoculated with the fungus resembling G. mosseae was associated with a greater amount of mycorrhizal roots. Responses in nodulation closely paralleled responses in growth. Non-mycorrhizal plants produced more dry matter at a given phosphorus concentration in tops than did mycorrhizal plants.

The current study, performed in Castilla-La Mancha (Spain) in 2003–04, reports the growth, nutrition, tolerance to transplanting stress, and resistance to Verticillium dahliae of olive plantlets (Olea europaea L.) inoculated with different arbuscular mycorrhizal (AM) fungi (Glomus mosseae, G. intraradices and G. claroideum). Inoculated plants tolerated the stress of transplanting better than non-inoculated plants. Compared with controls, plantlets inoculated with any of these three Glomus species grew taller, had more and longer shoots, and showed higher plant N, P and K concentrations. However, colonization seemed to have no influence on resistance to V. dahliae.

Arbuscular mycorrhizal (AM) fungi are obligatory biotrophic symbionts living in the roots of most terrestrial plants. AM fungi (AMF) have a positive effect on plant growth and plant nutrition, especially under stress conditions.  The aim of the present study was to observe the relationship between the mycorrhizal dependency and nutrient uptake of host plants and the rate of AMF colonization in a pot experiment. The degree of host growth responses to AMF colonization is expressed as mycorrhizal dependency (MD).  The pot trial was set up with a sterilized calcareous chernozem soil from Nagyhörcsök (Hungary) in a growth chamber under controlled climatic conditions. Tomato (Lycopersicon esculentum L.) plants were inoculated with Glomus claroideum (BEG23) , Glomus fasciculatum (BEG53), Glomus geosporum (BEG11), Glomus mosseae (BEG12) strains and a Glomus mosseae AMF culture produced by authors. The dry biomass production, the micro- and macronutrient concentrations of the shoots and the parameters of the mycorrhizal infection were determined. Each AM fungi species or isolate caused different and distinct changes in host plant growth and nutrient uptake. The biomass production of tomato increased significantly in the presence of AM symbiosis. The mean values of MD, calculated from shoot dry matter, varied between 36% and 55%. Mycorrhizal inoculation improved the P, N and K uptake of tomato. The highest values for root colonization, frequency of infection or arbuscular richness were found in the root of tomato inoculated with the two Glomus mosseae strains. The highest MD and nutrient contents appeared in the shoot of tomato treated withour Glomus mosseae strain, which may indicate a stronger affinity (compatibility) between the symbiotic partners. The results confirmed that the selected AMF strains are applicable in sustainable horticulture.

The present paper represents the positive role of Arbuscular Mycorrhizal (AM) fungi as biofertilizers in strawberry. Experiments were carried out to assess the effectiveness of Trichoderma viride and AM fungi (Glomus mosseae and Acaulospora laevis) alone or in combination, on the growth and biomass production of strawberry. After 120 days, dual inoculation of A. laevis + T. viride showed maximum increase in plant height (30.5±0.3), fresh shoot weight (10.16±0.20), dry shoot weight (2.82±0.02), fresh root weight (6.70±0.10), total chlorophyll (0.841±0.05) and phosphorus content in root (1.13±0.02) as compared to control. However root colonization and AM spore number were maximum in G. mosseae + A. lavies (90.76±1.32) and in G. mosseae (211.16±2.56) respectively as compared to uninoculated plants. Triple inoculation of G. mosseae + A. laevis + T. viride (12.33± 057) was effective in increasing the leaf area.

Salvia officinalis (Sage) is a popular kitchen herb, member of mint (Lamiaceae) family has been cultivated for its wide range of medicinal values. Arbuscular mycorrhizae (AM) are beneficial symbionts for plant growth and development and offer a viable replacement of high input agricultural technology employed for production of environmentally hazardous fertilizers. Therefore, the present study was focused to analyze the effect of two AM fungi (Acalospora laevis and Glomus mosseae) along with Trichoderma viride, alone and in combination, on different growth parameters of S.officinalis in a green house pot experiment with sterilized soil. AM inoculum and T.viride showed significant increase of different growth parameters after 45 and 90 days of inoculation. Among all treatments, dual combination of A.laevis plus T.viride was most effective in increasing shoot length, leaf area, root length, root weight, AM spore number and percent root colonization. Moreover, maximum increase in shoot biomass was found in plant treated with T.viride.

AbstractShort chain chitooligosaccharides (COs) are chitin derivative molecules involved in plant-fungus signaling during arbuscular mycorrhizal (AM) interactions. In host plants, COs activate a symbiotic signalling pathway that regulates AM-related gene expression. Furthermore, exogenous CO application was shown to promote AM establishment, with a major interest for agricultural applications of AM fungi as biofertilizers. Currently, the main source of commercial COs is from the shrimp processing industry, but purification costs and environmental concerns limit the convenience of this approach. In an attempt to find a low cost and low impact alternative, this work aimed to isolate, characterize and test the bioactivity of COs from selected strains of phylogenetically distant filamentous fungi: Pleurotus ostreatus, Cunninghamella bertholletiae and Trichoderma viride. Our optimized protocol successfully isolated short chain COs from lyophilized fungal biomass. Fungal COs were more acetylated and displayed a higher biological activity compared to shrimp-derived COs, a feature that—alongside low production costs—opens promising perspectives for the large scale use of COs in agriculture.
