Transport processes in the arbuscular mycorrhizal symbiosis
… and fungus is the key element of the arbuscular mycorrhizal (AM) symbiosis. The fungus improves the plant’s uptake of mineral nutrients, mainly phosphate, and water, while the plant provides the fungus with photosynthetically assimilated carbohydrates. Still, the knowledge about the mechanisms of …

Harnessing the genetic potential for arbuscular mycorrhizal symbiosis in rice
Arbuscular mycorrhizal fungi (AMF) have long been recognised to form a mutually beneficial symbiosis with over 80% of land plants present today. The symbiosis provides an integral link to mineral nutrients in the soil (Bago et al., 2000; Jakobsen & Rosendahl, 1990; Smith & Read, 2008) and this has …

Evolutionary conservation of host responses to arbuscular mycorrhizal symbiosis in liverworts
Arbuscular mycorrhizal symbiosis (AMS) arose in land plants more than 400 million years ago, perhaps acting as a major contributor to plant terrestrialization. The ability to engage in AMS is evolutionarily conserved across most clades of extant land plants, including early diverging bryophytes. …

Evolution and Function of Receptor-like Kinases in Arbuscular Mycorrhizal Symbiosis
… mutualism between plants and arbuscular mycorrhizal (AM) fungi was crucial to evolution of life, as it enabled the conquest of the green lineage and its ecosystem on land. Today, apart from AM fungi, plants co-exist with a plethora of micro-organisms, and exactly how the plant immune …

Spatio-temporal regulation of pre-symbiotic signalling in arbuscular mycorrhizal symbiosis
Arbuscular mycorrhizal (AM) symbiosis is a ubiquitous and ancient interaction between plant roots and Glomeromycotina fungi, underpinned by a mutualistic nutrient exchange. In this intimate partnership, the fungus dynamically and asynchronously colonises the plant root system and cortex cells. …

Analysis of Medicago truncatula transcription factors involved in the arbuscular mycorrhizal symbiosis
… distinct root cortex cells during the arbuscular mycorrhizal (AM) symbiosis was investigated by combining Laser Capture Mirodissection and Affymetrix GeneChip® Medicago genome array hybridization. The establishment of cryosections facilitated the isolation of high quality RNA in sufficient amounts …

D14-LIKE: An essential protein for the establishment of arbuscular mycorrhizal symbiosis
… the majority of land plants engage in symbiosis with arbuscular mycorrhizal (AM) fungi. The accommodation of fungal colonisation structures in the roots requires their radical reprogramming. This starts during pre-symbiotic communication, where signals are exchanged between the fungus …

Phosphate homeostasis and posttranscriptional gene regulation during arbuscular mycorrhizal symbiosis in Medicago truncatula
… interactions between plant roots and arbuscular mycorrhizal (AM) fungi are a widespread strategy to improve plant phosphate nutrition. The repression of AM symbiosis by a high plant Pi-status indicates a link between Pi homeostasis signalling and AM symbiosis development. This assumption is …

The role of SPARK-I receptor-like kinases in the arbuscular mycorrhizal symbiosis
… formed between land plants and arbuscular mycorrhizal (AM) fungi involves intracellular accommodation of the fungal symbiont and relies on concerted cellular reprograming. Maximal physical interaction is achieved during the emergence and development of the arbuscules, creating a hub for …

Cooperation and Punishment in the Arbuscular Mycorrhizal Symbiosis: Implications for Resource Exchange & Biological Market Dynamics
<p>The arbuscular mycorrhizal (AM) symbiosis is arguably the world’s most abundant and important mutualism, and brings together the roots of the majority of land plants and AM fungi to great mutual advantage. The AM symbiosis can increase the uptake of nutrients, such as phosphorus (P) and nitrogen …

Molecular and Physiological Aspects of Arbuscular Mycorrhizal Symbiosis with near-Isogenic White Clover: A Gene Expression Study
… Rhizobium and phosphate-scavenging arbuscular mycorrhizal fungi (AMF). Understanding the genetic control of plant-AM interactions will allow clover breeders to develop genetic markers for selection of phenotypes favourable to AM symbiosis.<br/><br/>Clover is normally an out-breeding species. …

Phosphate homeostasis and novel microRNAs are involved in the regulation of the arbuscular mycorrhizal symbiosis in Medicago truncatula
Die arbuskuläre Mykorrhiza ist die wahrscheinlich älteste Form der Wurzelsymbiosen zwischen Pflanzen und Pilzen und hat sich vor 420 Millionen Jahren entwickelt. In dieser Symbiose, die zwischen nahezu allen Landpflanzen und Pilzen des Reiches Glomeromycota ausgebildet wird, versorgt der Pilz die …

Impact of mycorrhizal fungi and nematodes on growth of Andropogon gerardii Vit., soil microbial components and soil aggregation
Biotic interactions among mycorrhizal fungi, nematodes, plants and other microbial communities can have significant effects on the dynamics of C and nutrient cycling. The specific objectives of this study were (1) to evaluate the effects of grazing and mycorrhizal symbiosis on the allocation and …

Invisible to arbuscular mycorrhizal fungi: Positional cloning and characterisation of a novel arbuscular mycorrhizal mutant in Zea mays
Arbuscular mycorrhizal fungi from the Glomeromycotina form a beneficial symbiotic relationship with the root systems of a majority of plant species, enabling plants to profit from increased phosphate uptake efficiency. Further understanding of this interaction may prove vital in meeting the …

Analysis of gene expression, regulation and function of three symbiotic ABC subfamily-B transporters in Medicago truncatula
… soil bacteria called rhizobia (Root Nodule Symbiosis) and fungi which assist in the acquisition of phosphate, collectively called arbuscular mycorrhizae (Arbuscular Mycorrhizal Symbiosis). Establishment of functional beneficial symbioses requires successful microbial infection. An initial …

Common Accommodation Mechanisms for Mutualistic and Detrimental Fungi in Oryza sativa (Rice) Roots
Rice roots engage in symbiosis with ancient symbiotic fungi such as R. irregularis, whilst resisting invasion of the detrimental fungus M. oryzae, a major causative agent of the rice blast (leaf) disease. M. oryzae can also invade rice roots with simple non-melanised hyphopodia formed on the rice …
