Opis:: Arbuscular mycorrhizal fungi (AMF) and dark septate endophyte (DSE) associations were studied in 36 medicinal plant species from 33 genera and 17 families, collected from the Botanical Garden of the Jagiellonian University in Kraków. Arbuscular mycorrhiza (AM) was found in 34 species (94%); 26 were of the Arum-type, 4 – Paris and 4 taxa revealed intermediate morphology. The abundance of AMF hyphae in roots varied with particular species, ranging from 2.5% (Helianthus tuberosus) to 77.9% (Convallaria majalis). The mycelium of DSE was observed in 13 plant species (36%), however, the percentage of root colonization by these fungi was low. Spores of 7 AMF species (Glomeromycota) were isolated from trap cultures established from rhizosphere soils of the investigated plants: Archaeospora trappei (Archaeosporaceae), Glomus aureum, Glomus caledonium, Glomus claroideum, Glomus constrictum, Glomus mosseae, Glomus versiforme (Glomeraceae). Our results are the first detailed report of root endophyte associations of the plant species under study. Moreover, the mycorrhizal status of 14 plant species is reported for the first time.

Opis:: Abscisic acid (ABA) is an ubiquitous plant hormone and one of the foremost signalling molecules, controlling plants' growth and development, as well as their response to environmental stresses. To date, the function of ABA has been extensively investigated as an abiotic stress molecule which regulates the plants' water status. However, in the context of symbiotic associations, ABA is less recognized. In contrast to well-described auxin/cytokinin and gibberellin/strigolactone involvement in symbioses, ABA has long been underestimated. Interestingly, ABA emerges as an important player in arbuscular mycorrhiza and legume-rhizobium symbiosis. The plant's use of stress hormones like ABA in regulation of those interactions directly links the efficiency of these processes to the environmental status of the plant, notably during drought stress. Here we provide an overview of ABA interplay in beneficial associations of plants with microorganisms and propose ABA as a potential factor determining whether the investment in establishing the interaction is higher than the profit coming from it.

Opis:: Zinc (Zn) is an important element for the proper plant growth and development. However, Zn is also a metal commonly used in the industry, which may cause its excessive accumulation in soil. High soil Zn content leads to its increased uptake by plants growing near industrialized areas. Arbuscular mycorrhizal fungi (AMF) live in symbiosis with the majority of plant species. These fungi have the ability to reduce Zn uptake by plants, when this element is present in an increased concentration in the plant root zone. An experiment was carried out to determine the effect of AMF on Zn uptake by lettuce plants grown in rockwool at increasing levels of Zn in the nutrient solution. This effect was investigated at two P levels in the nutrient solution, i.e. 40 mg P (optimal for lettuce) and 10 mg P dm-3. Mycorrhizal parameters, yield, content of dry matter, ascorbic acid, glucose, fructose and sucrose as well as the plant’s nutritional status in P, Cu, Mn, Mo, Fe and Zn were determined in the study. The effectiveness of mycorrhization of lettuce grown in rockwool was proven in the study. AMF reduced the Zn content in lettuce grown under excessive Zn concentrations in the root zone. Moreover, this decrease was greater in plants receiving the nutrient solution with a lower concentration of P. Additionally, mycorrhiza decreased the content of Cu, Fe, Mn and Mo in lettuce, despite an optimal (not increased) concentration of these micronutrients in the nutrient solution supplied to plants. Arbuscular mycorrhiza did not affect the plant yield, content of ascorbic acid, glucose, fructose, sucrose or the content of P in lettuce leaves.

Opis:: This is the first report of an ecological investigation on endomycorrhizal symbiosis in Curcuma aeruginosa, a medicinally and nutritionally important herb. Samples were collected from the field, where the plant grows under natural condition. AM fungal and soil fertility parameters were analysed as per standard methods. Altogether 16 different AM fungal species from seven different soil series are discovered. AM fungal species composition varied among soil series. Species richness of AM fungi was positively correlated with organic carbon content of soil. Shannon's diversity index and Simpson's index in the study area were measured. High intensity of AM fungal colonization in the roots of naturally growing C. aeruginosa suggests the need of proper management of the association in its cultivation practices also. Data obtained from the present investigation may help for the development of native AM fungi based biofertilizer based for a sustainable soil fertility management and cultivation of the crop.

Opis:: The effect of arbuscular mycorrhizal fungi (Glomus geosporum) inoculation on Telfairia occidentalis grown in saline soil was investigated in a pot experiment. The experiment was laid out in a completely randomized design, with treatments replicated thrice. Standard recommended methods were used to determine photosynthetic pigments, minerals contents, biomass yield, AMF colonization and dependency. Our results show that saline soil treatment significantly (p=0.05) reduced total photosynthetic pigments contents - from 39.73 to 21.30 mg/kg, percentage AMF root colonization - from 53.97 to 22.41%, mineral contents; N - from 5.84 to 3.13%; P - 424.11 to 212.31 mg/kg; K - 3215.00 to 1220.00 mg/kg; Mg - 326.00 to 107.04 mg/kg; and Ca - 1640.00 to 813.00 mg/kg. Biomass yield of T. occidentalis was also significantly (p=0.05) reduced. In contrast, mycorrhizal dependency was significantly (p=0.05) increased in saline soil plants - from 15.13% to 100.00%. Herein, inoculation with G. geosporum significantly (p=0.05) increased total photosynthetic pigments - from 39.73 to 45.53 mg/kg; N - from 5.84 to 6.07%; P - 424.11 to 463.00 mg/kg; K - 3215.00 to 3470.12 mg/kg; Mg - 326.00 to 345.00 mg/kg and Ca -1640 to 1658.12 mg/kg; leaf dry weight - from 0.13 to 0.17g; vine dry weight - 5.21 to 5.81g; roots dry weight - 0.57 to 1.03 and total dry weight - 5.91 to 7.01g. Biomass yield was also significantly increased. R. irregularis colonization (from 22.41 to 53.97%) and mycorrhizal dependency in C. maxima was evident in both saline and non-saline soil treatments. The results of this work have shown that G. geosporum can enhance the ability of T. occidentalis to resist salt stress (possibly through several morphological/physiological changes and through improved vigour) via the extensive network of the mycorrhizal roots (which increases nutrient and water uptake). Inoculation with appropriate AMF can, therefore, be used to increase the productivity of T. occidentalis in saline soils.

Opis:: In December 1997 and June-July 2000, 49 and 113 rhizosphere soil and root mixtures were collected, respectively, to determine the occurrence of arbuscular mycorrhizal fungi (AMF) of the phylum Glomeromycota in different sites of Israel. Except for five samples taken from under cultivated plants, all the others came from under Ammophila arenaria and Oenothera drummondii colonizing sand dunes adjacent to the Mediterranean Sea. After a continuous cultivation of the mixtures in pot trap cultures with Plantago lanceolata as the plant host up to 2006 and their examination at least twice a year, spores of AMF were found in 41 and 103 cultures with the 1997 and 2000 soil and root mixtures, respectively. The spores represented 30 species and 8 undescribed morphotypes in 7 genera of the Glomeromycota. The AMF most frequently found in Israeli soils were Glomus aurantium and G. constrictum, followed by G. coronatum, G. gibbosum, an undescribed Glomus 178, and Scutellospora dipurpurescens. Up to 2001, 21 species of AMF were known to occur in Israel, and this paper increases this number to 33, of which 11 are new fungi for this country. Moreover, four species, G. aurantium, G. drummondii, G. walkeri and G. xanthium, were recently described as new for science based on spores isolated from Israeli soils. Additionally, the general distribution in the world of the formally described species found in Israel was presented.

Opis:: Applying the biological product of arbuscular mycorrhiza fungi (AMF) is considered an effective strategy to improve crop productivity to cope with climate change in current agricultural production. The experiment was conducted to evaluate the impact on growth, yield, and secondary metabolites of medicinal mondo grass under rainfed conditions. The split-plot design was used with the main factor of six various AMF doses (0, 100, 200, 300, 400, and 500 kg·ha-1 year-1) and the sub-factor of two mondo grass genotypes (G1 and G2). AMF supplement had positive effects on both genotypes in increasing canopy size, the number of leaves and tillers, root growth, leaf osmotic pressure and chlorophyll fluorescence, total biomass, yield components, uptake of macronutrients, contents of polysaccharide, saponin, flavonoid, and decreasing leaf water deficit and ion leakage. G2 a higher drought-tolerant genotype performed better than G1 for investigated characteristics (except canopy height and SPAD), but the effect of AMF was clearer in the G1 genotype. Supplement of 300 kg AMF ha-1 year-1 could be the optimum rate for growth and medicinal quality of mondo grass under rainfed conditions.

Opis:: The influence of mycorrhizal fungi (Rhizophagus irregularis) on salt tolerance of Cucurbita maxima grown in saline soil was investigated in a pot experiment. The experiment was laid out in a completely randomized design, with treatments replicated thrice. Accordingly, soil salinity significantly (p=0.05) reduced total photosynthetic pigments from 58.06 to 38.06 mg/kg. Mineral contents, biomass yield, AMF colonization were also significantly (p=0.05) reduced. In contrast, mycorrhizal dependency was significantly (p=0.05) increased in saline soil plants (from 26.91% to 66.45%). Furthermore, inoculation with R. irregularis significantly (p=0.05) increased total photosynthetic pigments from 58.06 to 62.06 mg/kg; N from 4.88 to 5.47%; P 860.40 to 896.22 mg/kg; K 4430.00 to 4630.00 mg/kg; Mg 558.99 to 592.10 mg/kg and Ca 2810.00 to 3151.00 mg/kg; biomass yield; leaf dry weight from 0.06 to 0.14g; vine dry weight 3.68 to 5.09g; roots dry weight 0.32 to 0.74 and total dry weight 4.06 to 5.97g, R. irregularis colonization (from 33.77 to 58.44%) and mycorrhizal dependency in C. maxima was evident in both saline and non-saline soil treatments. The results of this work shows that R. irregularis can enhance the ability of C. maxima to resist salt stress - possibly through some morphological/ physiological changes, as well as improved vigour, probably via the extensive network of the mycorrhizal roots. This last is considered to be one of several mechanisms that magnify the salt tolerance of host plants through increased nutrient acquisition (N, P, K, Mg and Ca) and water uptake. Inoculation with appropriate AMF can, therefore, be used to increase the productivity of C. maxima in saline soils.

Opis:: This study was carried out to determine some morphological and physiological reactions to the application of organic bio-stimulants, arbuscular mycorrhizal fungus (AMF) and whey (W), which were used against the negative results of salt stress in the cuttings of the Ercis grapevine cultivar. The cuttings were rooted in pots filled with perlite with no drainage. Once the cuttings were rooted, the buds were formed and the nodes extended, the salt application was initiated. The budded cuttings were irrigated with 1% Hoagland Nutrient Solution added with three different NaCl concentrations (0, 50 and 100 mmol). Moreover, AMF, W, and AMF+W were applied and the response of the budded cuttings against salt stress was monitored. As well as making analyses of macro- and microelements (P, K, Ca, Na, Mg, Fe, Mn, and Zn) in the shoots and roots, some parameters, such as shoot diameter, shoot height, root width, root length, number of leaves, fresh shoot weight, dry shoot weight, fresh root weight, dry root weight and leaf water content (LWC) were investigated, and the salt amount in the growth media was determined. At the end of the study, it was shown that AMF, W, and their combination (AMF + W), which had been applied against the physiological and morphological changes induced by salt stress and its adverse effects, had a positive effect on the majority of the parameters compared to the control group. Moreover, it was demonstrated that the use of AMF and W in the context of sustainable viticulture would be beneficial in terms of promoting the rooting and development of cuttings and protecting the plants against soil salinity that creates abiotic stress.

Opis:: Plant growth and physiological response of sesame (Sesamum indicum L.) were studied in controlled environment using normal soil and indigenous Vesicular-arbuscular mycorrhiza (VAM) fungi treated soil. The seedlings of Zea mays were inoculated with Giguspora species of VAM (Glomus fasiculatum) and the inoculum was multiplied with help of Zeamays seed bed. Sesame seeds were then inoculated into the bed and it was found that the plant height, shoots lengths, roots, biomass of shoot and roots were considerably increased in the mycorrhizal plants. The effect of VAM infection was assessed in pot experiment. In this comparative study, specific mycorrhizal fungi had consistent effects on various growth parameters such as the number of leaves, number of roots, shoot length, biomass of shoot and roots and biochemical parameters were observed at various time intervals by statistical analysis using two way ANOVA, it was confined with mycorrhizal and non-mycorrhizal infected plants. It was found that the ability of isolates to maintain the plant growth effectively in the case of mycorrhizal seedlings shows a maximum absorbtion of 0.77 ±0.2, shoot length is about 8.34 ±0.2, count of root and leaves are about 8.10 ±0.3, 5.6 ±0.3 respectively under mycorrhizal infection in 30days of analysis and had a positive effect on the growth at all intervals. Biochemical analysis were carried out to estimate the total chlorophyll, chrophyll A, chlorophyll B and Carotenoids contents and it was analyzed to be 9 ±0.5 mg/g, 8.3 ±0.5 mg/g, 3.6 ±0.5 mg/g, 4 ±0.3 mg/g respectively. At the 30th day of analysis for the mycorrhizal plants, it was found to be high in mycorrhizal seedlings which shows the symbiosis had improved the nutrient uptake of cultivated plants. Nevertheless G. fasiculatum was found to be the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.
