Journal of Tropical Mycorrhiza is an international journal devoted to research into mycorrhizas - the widest symbioses in nature, involving plants and a range of soil fungi world-wide. The journal covers research into mycorrhizas, including molecular biology of the plants and fungi, fungal systematics, development and structure of mycorrhizas, and effects on plant physiology, productivity, reproduction and disease resistance. Coverage extends to interactions between mycorrhizal fungi and other soil organisms, and effects of mycorrhizas on plant biodiversity, ecosystem structure, reclamation and restoration of degraded land. Journal of Tropical Mycorrhiza presents original papers, short notes and review articles, along with commentaries and news items. It offers a platform for new concepts and discussions, and serves as the basis for a forum of mycorrhizologists from around the world.

Abstract

The use of chemical compounds in intensive agricultural systems triggers an increase in residual heavy metal compounds such as Pb and has the potential to be a pollutant in the soil and water environment. This study aims to test the effectiveness of several types of phytoremediation plants in absorbing lead (Pb) with the application of arbuscular mycorrhizal fungi originating from two different types of land (rice fields and dry land).The research method used a factorial design based on a Randomized Group Block Design, consisting of two factors, namely the type of mycorrhizal isolate originating from rice fields and dry land, and three types of phytoremediation plants, namely sunflowers, napa cabbage (Brassica pekinensis L.) and citronella (Cymbopogon nardus L.), with three replications and two plants units totaling 54 experimental units. The results showed that mycorrhiza from rice fields increased the percentage of Pb compound absorption capacity of phytoremediation plants compared to mycorrhiza from rice fields. The growth of phytoremediation plants tends to be better with the presence of mycorrhiza symbiosis. Sunflowers have the highest average Pb absorption capacity of 73%, while citronella can absorb Pb well even without mycorrhiza.

Abstract

The production of arbuscular mycorrhizal fungi (AMF) propagules is highly necessary for AMF-based biofertilizer production. This research was conducted to ustudy the dynamics of spore populations in mass propagation of AMF propagules in two greenhouses. AMF propagule propagation was carried out in vitro using sorghum plants as host plants grown in 5 kg capacity polybags totaling 200 polybags in all. The results showed that the reactions of both greenhouse H and greenhouse I media was acidic. There was a dynamics of AM fungi spore populations in those both green houses. Regrowth of sorghum plants (up to ratoon 2) failed to increase the density of AMF spore populations in both ratoon 1 and ratoon 2, and there was even a decrease in AMF spore populations at some incubation days. Drying of media could decrease or increase spore density in propagation in greenhouse H, while agitation to increase aeration couldn't enhance spore populations. In greenhouse I, neither agitation nor drying could increase the number of AMF spores. The highest spore population obtained from greenhouse H with a total propagation period of 49 weeks (12 months 1 week, ratoon 2) was observed at the beginning of maintenance of the second plant (ratoon 1), reaching 8.3 spores g-1, while for greenhouse I with a longer total time of 53 weeks (13 months 1 week, ratoon 2), the highest spore population was at the end of drying in the maintenance of the third plant (ratoon 2), reaching 6.7 spores g-1

Abstract

Siompu tangerine (Citrus nobilis Lour.) is an endemic plant from Siompu Island, This plant is rare and slow to bear fruit due to generally being cultivated generatively. This study aims to determine the effect of natural growth regulators combined with Arbuscular Mycorrhizal Fungi on the success of Siompu tangerine shoot cuttings. This research was conducted in the plastic house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi Branch Universitas Halu Oleo (UHO) and the Kendari Forestry and Environmental Sciences Laboratory Unit, which lasted for 5 months from September to February 2025. This study used a Randomized Block Design consisting of 9 treatments, namely control (a), aloe vera solution (b), shallot solution (c), AMF Inoculum of Kaimbulawa Village (d), AMF Inoculum of Lapara (e), Aloe vera solution + AMF Inoculum of Kaimbulawa Village (f), Aloe vera solution + AMF Inoculum of Lapara (g), Shallot solution + AMF Inoculum of Kaimbulawa Village (h) and Shallot solution + AMF Inoculum of Lapara ( i ) each treatment consisted of three replications and each replication consisted of five plants so that the total plants used were 135 plants. The results showed that the treatment of natural growth regulator combined with AMF had not provided significant results on the Percentage of living cuttings, the percentage of cuttings that sprouted, and the number of leaves. In the Kaimbulawa AMF treatment, it can increase the rate of rooted cuttings, and the 100% natural shallot PGR treatment combined with Lapara FMA increases root length and the percentage of AMF colonization

Abstract

This quantitative descriptive research aimed to describe the antimicrobial activity and phylogenetic relationships of Actinomycetes from the rhizosphere of pandan (Pandanus spp.). Soil samples were taken from three different villages in Gorontalo Regency, including Bontula Village, Asparaga Sub-district, Lombongo Village, Suwawa Tengah Sub-district, and Moutong Village, Tilongkabila Sub-district, Bone Bolango Regency. Isolation was carried out using SCA media, resulting in six Actinomycetes isolates with different colony morphologies. Antimicrobial activity tests were carried out using the cross-streak method against Escherichia coli, Staphylococcus aureus, Candida albicans, Fusarium oxysporum, and Neocosmospora solani. The results showed that only one isolate, IRzP-at.k, showed significant antimicrobial activity, against Escherichia coli and Staphylococcus aureus with inhibition zones of 13,31 mm and 13,67 mm, respectively. The IRzP-at.k isolate also showed inhibition against Candida albicans and Fusarium oxysporum with inhibition zones of 34,12 mm and 11,25 mm, but did not show inhibition against Neocosmospora solani. Phylogenetic analysis based on 16S rRNA gene sequences identified the isolate as closely related to Streptomyces vinaceusdrappus (97.42% similarity). This research indicated the potential of the IRzP-at.k isolate as a source of new antimicrobial compounds and strengthens the role of the pandan rhizosphere as a habitat rich in Actinomycetes.
