<strong>Objective</strong>. Obtain an in vitro mycorrhization system in autotrophic culture systems of blackberry plants (Rubus glaucus, Benth). <strong>Materials and methods</strong>. We used spores and root fragments with vesicles of Arbuscular Mycorrhizal Fungus (AMF) Glomus sp (GEV02). We established an autotrophic culture system of blackberry plantlets comparing two methods of direct inoculation of the AMF. We measured the number of spores produced, the length of the extraradical mycelium as well as the percentage of colonization of the AMF. Additionally, we measured the shoot and root length, and the fresh and dry weight of the leaf and root parts to determine the plant development. <strong>Results</strong>. The autotrophic culture system was successful for blackberry plants (Rubus glaucus, Benth; an optimal shoot and root growth was observed. Additionally, we obtained a system that allowed the development of Glomus sp. in in vitro conditions, with the formation of structures typical of the symbiosis as well as a good intraradical colonization, with the production of arbuscules and vesicles, development of extraradical mycelium with branched hyphae, and formation of new spores. <strong>Conclusion</strong>. For the first time, micropropagated blackberry plants associated successfully with an AMF under in vitro conditions, enabling the development of the symbiotic system AMF Glomus sp. associated to roots of micropropagated blackberry plantlets.<br /><strong>Key words</strong>: arbuscular mycorrhizal fungi (AMF), autotrophic culture, Rubus glaucus Benth, Glomus sp.

AbstractArbuscular mycorrhiza fungi (AMF) are beneficial soil fungi that can promote the growth of their host plants. Accurate quantification of AMF in plant roots is important because the level of colonization is often indicative of the activity of these fungi. Root colonization is traditionally measured with microscopy methods which visualize fungal structures inside roots. Microscopy methods are labor-intensive, and results depend on the observer. In this study, we present a relative qPCR method to quantify AMF in which we normalized the AMF qPCR signal relative to a plant gene. First, we validated the primer pair AMG1F and AM1 in silico, and we show that these primers cover most AMF species present in plant roots without amplifying host DNA. Next, we compared the relative qPCR method with traditional microscopy based on a greenhouse experiment with Petunia plants that ranged from very high to very low levels of AMF root colonization. Finally, by sequencing the qPCR amplicons with MiSeq, we experimentally confirmed that the primer pair excludes plant DNA while amplifying mostly AMF. Most importantly, our relative qPCR approach was capable of discriminating quantitative differences in AMF root colonization and it strongly correlated (Spearman Rho = 0.875) with quantifications by traditional microscopy. Finally, we provide a balanced discussion about the strengths and weaknesses of microscopy and qPCR methods. In conclusion, the tested approach of relative qPCR presents a reliable alternative method to quantify AMF root colonization that is less operator-dependent than traditional microscopy and offers scalability to high-throughput analyses.

White ash seedlings (Fraxinusamericana L.) were inoculated with five species of endomycorrhizal fungi. On the 2nd week after transplantation, growth of inoculated plants differed from control plants. Growth also differed between each fungal species used, but the difference decreased after 82 days of culture. Only dry mass remained higher in plants inoculated with Glomusepigaeum Daniels & Trappe, Glomus sp. No. 3, and Glomusmonosporum Gerd. & Trappe. A significant growth enhancement was obtained even with a low level of root colonization.

biodegradable polymer such as PVA is considered the most promising candidates for developing the sustainable sticker. The objective of this study was to determine the most suitable PVA + TS blends as adhesives agent for AMF spores inoculation via seed coating which can enhance the spores viability and their beneficial properties in maize. The polythene bag experiment was performed in a screen house of the Department of Plant Protection Faculty of Agriculture, University of Bengkulu Indonesia in 2015. Six adhesive blends were employed: 100% PVA + 0% TS, 75% PVA + 25% TS, 50% PVA + 50% TS, 25% PVA + 75% TS, 0% PVA + 100% TS, and no coating. The six experimental treatments were laid out in a completely randomized design with three replications. The results show that root colonization, AMF spore population, and shoot dry weight in 75% PVA + 25% TS were equal to those in 100% PVA. Root colonization, AMF spore population, shoot P content, and shoot P concentration were greater for 50% PVA + 50% TS than 100% PVA, 100% TS, and no coating. A mixture of 50% PVA + 50% TS was considered the preferred sticker. Thus, the tapioca starch can be used to substitute 25 - 50% of the PVA used without reducing AMF inoculant adhering to seed.Keywords: polymeric seed coating, seed coating formulation, arbuscular mycorrhizal fungi, sustainable coating adhesive, seed inoculation, seed inoculant

AbstractAgarwood (Aquilaria malaccensis) is one of the non-timber forest products that has high economic value. However, this plant grows very slowly.  Therefore, seed technology input is needed, such as addition of arbuscular mycorrhizal fungi (AMF). The objectives of this research were to study the effect of AMF inoculum i.e. Glomus sp., Gigaspora margarita and mixture of both species on agarwood growth and to determine the best AMF type for agarwood seedlings growth. The experimental research design used was a completely randomized design with three treatments, namely Glomus sp. (G), G. margarita (Gi) and a mixture of Glomus sp. and G. margarita (GGi) and without AMF inoculation (K) with each treatment repeated 8 times. The number of AMF spores used was ± 300 spores/seedling, and applied at the time of transplanting from germination tray to the polybag. Data were processed using analysis of variance and least significant difference test (LSD). The results showed there was AMF colonization in agarwood roots after 12 weeks of inoculation with the highest percentage at 20.50% on G. margarita treatment. Overall, AMF improved the growth of agarwood seedlings. The best seedlings growth was in the treatment of mixed AMF (GGi). Increased growth was found in plant height (14.68 cm), seedling diameter (2.16 mm), leaf area (119.30 cm2), root volume (1.15 mL), total dry weight (0.83 g), and shoot root ratio (4.99).[Keywords: agarwood, A. malaccensis,AMF, G. margarita,Glomussp.]AbstrakGaharu (Aquilariamalaccensis) adalah salah satu hasil hutan bukan kayu yang memiliki nilai ekonomis tinggi.

This research evaluated the changes on populations of culturable N-fixing free bacteria (NFFB) and P-solubilizing bacteria (PSB), as well as on the root nodulation by native rhizobia, the root colonization and spore number of arbuscular mycorrhizal fungi (AMF), in the rhizosphere of Clitoria ternatea and Brachiaria brizantha grown in mesocosms contaminated with crude oil (0, 3000, 6000, 9000, and 12000 mg kg-1), for 240 days. After 24 h of soil contamination, the highest populations of NFFB and PSB (5.5 and 4.9 LogUFC, respectively) were found in control, and the lowest populations were obtained at 12000 mg kg-1 (5.1 and 4.2 LogUFC, respectively). In contrast, at 60 and 240 days, the control showed lower populations of NFFB and PSB (5.4 and 4.8 LogUFC, respectively) than contaminated treatments. The highest number or root nodules in C. ternatea was quantified in control at 60 and 240 days (25 and 27 nodules, respectively) in comparison to those observed at the treatment with 12000 mg kg-1 (7 and 1 nodule, respectively). At 60 days, AMF colonization in both plant species, and the number of spores significantly decreased as the crude oil concentration increased; however, at 240 days, the highest number of AMF spores was recorded at treatments with 6000 and 12000 mg kg-1. The dry weight of both plant species significantly decreased as crude oil concentrations increased. Although C. ternatea was more susceptible to the toxic effects of crude oil, this plant species showed greater content of total chlorophyll than B. brizantha.

Catharanthus roseus L. (Apocynaceae), a valuable medicinal plant with potential therapeutic value was inoculated with AM fungi Glomus fasciculatum under three different phosphate conditions. Catharanthus roseus plants raised in presence of the AM fungi showed increased growth in terms of (shoot length, root length, leaf number, fresh weight and dry weight). Total chlorophyll content and phosphate content of the shoot was found to be significantly higher in AM inoculated plants as compared to non AM Catharanthus plants. The activities of phosphatase enzymes were found to be increased in AM inoculated plants as compared to non AM plants. Root colonization percent was significantly higher in AM inoculated plants at zero and at all three phosphate levels after 60, 90 and 120 days of AM inoculation, but decreased at third phosphate level after 120 days of AM inoculation. The study suggests that Catharanthus roseus is dependent on the mycorrhizal fungi to a large extent for its growth and survival and also shows the potential of AM fungi Glomus fasciculatum in increasing growth and biomass of Catharanthus roseus L.
