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 …

Transport processes in the arbuscular mycorrhizal symbiosis
… plant 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 …

SUCCESSION OF ARBUSCULAR MYCORRHIZAL FUNGI: CAUSES, CONSEQUENCES, AND CONSIDERATIONS
Arbuscular mycorrhizal fungi (AMF) are soil fungi associations with the majority of terrestrial plants. These fungi may affect a wide range of ecosystem processes from primary productivity to soil stabilization. Understanding the patterns and controls of AMF abundance during succession soil will be …

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 …

Effects of arbuscular-mycorrhizal fungal colonization on management of saline lands
… in this thesis was to evaluate the importance of arbuscular-mycorrhizal ( AM ) colonization of plants in management of saline lands. Some aspects of application of AM fungi in revegetation of saline lands are also reported. Effects of AM pre-inoculation on mycorrhiza-responsive and non-responsive …

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
… of the nutritional 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 …

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. …

Arbuscular mycorrhizal fungi enhance tolerance to bicarbonate in Rosa multiflora cv. burr
… Glomus Tulasne & Tulasne species inoculum of arbuscular mycorrhizal fungi (AMF), Glomus ZAC-19 (containing Glomus albidum Walker & Rhodes, Glomus claroideum Schenck & Smith, and Glomus diaphanum Morton & Walker), to enhance plant tolerance to HCO3- was tested on the growth and nutrient uptake …

Investigations of Bromus tectorum: restoration strategies and interactions with arbuscular mycorrhizal fungi
… B. tectorum to field and commercial sources of arbuscular mycorrizal fungi (AMF) inoculum. Bromus tectorum and early successional plant species were negatively responsive and late successional species were positively responsive to field AMF inoculum, while commercial inoculum was ineffective. I …

Analysis of Medicago truncatula transcription factors involved in the arbuscular mycorrhizal symbiosis
… of 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 …

D14-LIKE: An essential protein for the establishment of arbuscular mycorrhizal symbiosis
… 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 and plant across …

Establishment of Arbuscular Mycorrhizal Fungi (AMF) on micropropagated teak (Tectona grandis L. F.)
… ability to establish mycorrhizas from different Arbuscular Mycorrhizal Fungi (AMF) inoculum sources on two micropropagated teak (Tectona grandis L. f.) clones was examined at the acclimatisation phase. Teak shoots were maintained on a multiplication medium containing Murashige and Skoog (MS) …

Role of iron in the accumulation of glomalin, an arbuscular mycorrhizal fungal glycoprotein
Effects of iron on production of glomalin, an arbuscular mycorrhizal fungal glycoprotein, were examined. In a preliminary experiment comparing available (FeEDDHA) and unavailable iron (hematite), low amounts of glomalin were produced with the former while the latter total inhibited the symbiosis. …
