Two glomoid spore-producing arbuscular mycorrhizal fungi were grown in single-species cultures that established from soil-borne spores collected high altitude (2800 m a.s.l.) of Tibet Plateau, China. Phylogenetic analyses performed with sequences nuclear rDNA (spanning the partial small subunit, whole internal transcribed spacer, and large subunit segment; 18S-ITS-28S) largest RNA polymerase II...

The majority of achlorophyllous mycoheterotrophic plant species associate with arbuscular mycorrhizal fungi (AMF). Previous studies have shown that some species are highly specialized towards narrow lineages of AMF and have suggested that only particular lineages of these fungi are targeted by mycoheterotrophic plants. To test this hypothesis, we analyzed all available partial SSU sequences of ...

Comparative mitochondrial genomics of arbuscular mycorrhizal fungi (AMF) provide new avenues to overcome long-lasting obstacles that have hampered studies aimed at understanding the community structure, diversity, and evolution of these multinucleated and genetically polymorphic organisms.AMF mitochondrial (mt) genomes are homogeneous within isolates, and their intergenic regions harbor numerou...

Arbuscular mycorrhizal (AM) fungi are mainly thought to facilitate phosphorus uptake in plants, but they can also perform several other functions that are equally beneficial. Our recent study sheds light on the factors determining one such function, enhanced plant protection from root pathogens. Root infection by the fungal pathogen Fusarium oxysporum was determined by both plant susceptibility...

Arbuscular Mycorrhizal Fungi (AMF) are ubiquitous soil microorganisms playing a vital role in the functioning of agricultural ecosystems. Although AMF generally considered to have low host specificity, it has been suggested that modern plant breeding selected crop genotypes more selectively associated with AMF, possibly resulting high yielding varieties (HYV) having lower diversity than traditi...

Communities of arbuscular mycorrhizal fungi (AMF) in plant roots improve host growth. In this study, AMF communities the sago palm (Metroxylon sagu Rottb.) were investigated mineral soil (MS) and shallow peat (SPS) Sarawak, Malaysia. MS exhibited lower moisture content (MS, 38.1; SPS, 79.8%), higher pH (H2O) 4.6; 4.1), bulk density 1.03; 0.20 g cm?3), nitrogen 16.9; 2.7 kg m?3) than SPS at same...

1. Plants interact with many organisms, such as microbes and herbivores, and these interactions are likely to affect the establishment and spread of plants. In the context of plant invasions, mycorrhizal fungi and constitutive and induced resistance of plants against herbivores have received attention independently of each other. However, plants are frequently involved in complex multi-trophic ...

Abstract Tropical dry forests are an intricate ecosystem with special adaptations to periods of drought. Arbuscular mycorrhizal fungi (AMF) essential for plant survival in all terrestrial ecosystems but might be even greater importance as growth is limited due nutrient and water deficiency during the season. Ecuador highly endangered, studies about AMF communities scarce. We investigated commun...

Arbuscular mycorrhizal fungi (AMF) affect multiple ecosystem functions and processes, the assemblages of which vary across ecosystems. However, the influences of environmental factors on AMF communities which may shape these communities are still largely unknown. In this study, AMF communities from roots and rhizosphere soils of Chenopodium ambrosioides in different natural soils were investiga...

The arbuscular mycorrhizal (AM) fungi are a globally distributed group of soil organisms that play critical roles in ecosystem function. However, the ecological niches individual AM fungal taxa poorly understood. We collected > 300 samples from natural ecosystems worldwide and modelled realised virtual (VT; approximately species-level phylogroups). found environmental spatial variables jointly ...
