Mycorrhizal Potential

Diversity of arbuscular mycorrhizal fungi (AMF) is potentially important for the productivity and functioning of plant communities. However, from results published to date, it is unclear whether the increase in productivity and plant diversity obtained with increased AMF richness is a consequence of higher richness in itself or whether it is caused simply by an uncontrolled, higher mycorrhizal potential in the more diverse AMF inocula used. The aim of the present work was to evaluate the effect of AMF richness on the biomass and survival of several wild plant species from La Gran Sabana, Venezuela, comparing AMF inocula of varying richness but with similar mycorrhizal potential. We studied the effect of two inocula (containing two and five AMF species respectively, each with 600 propagules/100 g of soil) on growth and survival in a community composed of three woody species indigenous to La Gran Sabana. No differences were found in dry mass production or plant survival when the two inocula of contrasting richness were compared. Reasons for such results include the life history strategies of the AMF used in the present work.Key words: arbuscular mycorrhizal fungi, arbuscular mycorrhizal fungal diversity, microcosm, species richness, biodiversity, tropical species.

Abstract. Setyaningsih L, Dikdayatama FA, Wulandari AS. 2020. Arbuscular mycorrhizal fungi and Rhizobium enhance the growth of Samanea saman (trembesi) planted on gold-mine tailings in Pongkor, West Java, Indonesia. Biodiversitas 21: 611-616. Revegetation of severely degraded lands, such as gold-mine tailings, requires comprehensive approach including the selection of appropriate tree species and the improvement of soil fertility with the application of microorganisms. This study aimed to analyze the growth of trembesi (Samanea saman (Jacq.) Merr) seedlings inoculated with Arbuscular Mycorrhizal Fungi (AMF) and rhizobial bacteria (RB) on gold-mine tailings in Pongkor, Bogor, West Java, Indonesia. The AMF, RB, and mixture of AMF and RB were inoculated into S. saman seedlings and then the seedlings were grown on gold mine tailings land. Seedling growth, AMF infection and RB nodulation were observed after 12 weeks after planting. The results showed that the treatments facilitated AMF colonization by up to 20.7% and RB nodulation up to 22 nodules per plant. The inoculation of S. saman seedlings with AMF and RB significantly increased the growth on diameter, biomass, and root length, with values of root-to-shoot ratio of 3.1-4.3. The roots of S. saman seedlings were also able to penetrate the depth of the tailings solum. These results showed that AMF and RB application effectively increased the growth of S. saman seedlings in the gold tailings field.

Setyaningsih L, Wulandari AS, Hamim H. 2018. Growth of typha grass (Typha angustifolia) on gold-mine tailings with application of arbuscular mycorrhiza fungi. Biodiversitas 19: 454-459. Gold mine tailings contain extreme physical and chemical properties, which inhibit plant growth due to lower nutrition and higher heavy metal contaminants. Typha (Typha angustifolia) is type of grass growing well on waterlogged area including tailing dam. The objective of this study was to investigate the effect of arbuscular mycorrhizal fungi (AMF) in combination with compost and soil on the typha growth in gold mine tailings. The study was conducted in greenhouse by inoculating two AMF isolates (Glomus etunicatum and G. manihotis) to typha seedlings grown in pure tailing media, mixed tailing-compost media, and mixed tailing-compost-soil media. The compatibility and growth of typha grass were analysed after 1 month. Results showed that G. etunicatum and G. manihotis application significantly increased AMF colonization of typha roots up to 16.6% and 21.8% respectively. The length, number of leaves and biomass of typha also increased up to 90%, 50% and 97% respectively compared to those without AMF inoculation. G. etunicatum contributed the best growth of typha grown in mixed compost-soil-tailings, resulting in double increase of its length and biomass. The application of G. manihotis did not significantly increase the growth of typha in mixed media; however, under pure tailing, this mycorrhiza had the best induction for typha biomass and leaf number. In general, AMF application increased growth of typha grass in tailings media.

An experiments aimed to explore the effects of mycorrhizae inoculation on the potential of local plant species (Paspalum conjugatum, Cyperus kyllingia, and Lindernia crustacea) for phytoextraction of mercury from small-scale gold mine tailings contaminating agricultural land has been conducted in a glasshouse.  The first experiment was set up as three plant species, and doses of mycorrhizal inoculation, i.e. 0 and 30 spores/plant. At harvest of 63 days, shoots and roots were analyzed for mercury concentration, consisted of 6 treatments (PcM0; PcM1; CkM0; CkM1; LcM0; LcM1), and the second experiment  using the remediated soils of the first trials consisted of treatments (six treatments previous and one control) were used for growing maize 84 days. Each of the plant seedlings was planted in a plastic pot containing 10 kg of tailing and compost mixture. The results showed that Glomus was the most compatible mycorrhizae against the three types of host plants studied. Mycorrhizal inoculation significantly affected plant growth and biomass weight of three plant species. The highest Hg accumulation (56.3 mg/kg) was observed in the shoot of PcM1. Overall, the tested three plant species could be used for phytoextration of mercury from small-scale gold mine tailings contaminating agricultural land, but its interactions with mycorrhizae did not significantly affect the accumulation of mercury. Myco-phytoextraction of mercury significantly enhanced maize growth and biomass. Keywords: Cyperus kyllingia, Lindernia crustacea; Paspalum conjugatum; phytoremediation; gold mine tailings

The global demand for plant biomass to provide bioenergy and heat is continuously increasing because of a growing interest among many industrialized and developing countries towards climate sound and renewable energy supply. The exacerbation of land-use conflicts proliferates social-ecological demands on future bioenergy cropping systems. Perennial herbaceous wild plant mixtures (WPMs) represent an approach to providing social-ecologically more sustainably produced biogas substrate that has gained increasing public and political interest only in recent years. The focus of this study lies on three perennial wild plant species (WPS) that usually dominate the biomass yield performance of WPM cultivation. These WPS were compared with established biogas crops in terms of their substrate-specific methane yield (SMY) and lignocellulosic composition. The plant samples were investigated in a small-scale mesophilic discontinuous biogas batch test for determining the SMY. All WPS were found to have significantly lower SMY (241.5–248.5 lN kgVS−1) than maize (337.5 lN kgVS−1). This was attributed to higher contents of lignin (9.7–12.8% of dry matter) as well as lower contents of hemicellulose (9.9–11.5% of dry matter) in the WPS. Only minor, non-significant differences to cup plant and Virginia mallow were observed. Thus, when planning WPS as a diversification measure in biogas cropping systems, their lower SMY should be considered.

AbstractEarly-diverging fungi (EDF) are distinct from Dikarya and other eukaryotes, exhibiting high N6-methyldeoxyadenine (6mA) contents, rather than 5-methylcytosine (5mC). As plants transitioned to land the EDF sub-phylum, arbuscular mycorrhizal fungi (AMF; Glomeromycotina) evolved a symbiotic lifestyle with 80% of plant species worldwide. Here we show that these fungi exhibit 5mC and 6mA methylation characteristics that jointly set them apart from other fungi. The model AMF, R. irregularis, evolved very high levels of 5mC and greatly reduced levels of 6mA. However, unlike the Dikarya, 6mA in AMF occurs at symmetrical ApT motifs in genes and is associated with their transcription. 6mA is heterogeneously distributed among nuclei in these coenocytic fungi suggesting functional differences among nuclei. While far fewer genes are regulated by 6mA in the AMF genome than in EDF, most strikingly, 6mA methylation has been specifically retained in genes implicated in components of phosphate regulation; the quintessential hallmark defining this globally important symbiosis.
