A new method for observing the morphology of vesicular–arbuscular mycorrhizae
A new procedure using chlorazol black E has been developed for staining vesicular–arbuscular mycorrhizal fungi in cleared roots. In a comparative study, chlorazol black E was found to be much… Expand
Nitrate depletion and pH changes induced by the extraradical mycelium of the arbuscular mycorrhizal fungus Glomus intraradices grown in monoxenic culture.
The effect of the extraradical mycelium of the arbuscular mycorrhizal (AM) fungus Glomus intraradices Smith & Schenck on nitrate uptake and on the pH of the medium was studied in a monoxenic culture… Expand
Branched absorbing structures (BAS): a feature of the extraradical mycelium of symbiotic arbuscular mycorrhizal fungi
The present work describes the morphogenesis and cytological characteristics of ‘branched absorbing structures’ (BAS, formely named arbuscule-like structures, ALS), small groups of dichotomous hyphae… Expand
Flavonoid levels in roots ofMedicago sativa are modulated by the developmental stage of the symbiosis and the root colonizing arbuscular mycorrhizal fungus
Abundant data on the effect of flavonoids on spore germination, hyphal growth and root colonization by AMF are available. Moreover, the flavonoid pattern in mycorrhizal roots changes, thus flavonoids… Expand

The extent to which the N2-fixing bacterial endophyte Azoarcus sp. strain BH72 in the rhizosphere of Kallar grass can provide fixed nitrogen to the plant was assessed by evaluating inoculated plants… Expand
Architecture and developmental dynamics of the external mycelium of the arbuscular mycorrhizal fungus Glomus intraradices grown under monoxenic conditions
The structural development of arbuscular mycorrhiza extraradical mycelium is difficult to fol- low in soil-based systems. The use of dual arbuscular mycorrhizal fungi/in vitro root organ cultures… Expand
LIFE CYCLE OF GLOMUS INTRARADIX IN ROOT ORGAN CULTURE
The entire vegetative life cycle of the vesicular-arbuscular mycorrhizal fungus Glomus intraradix was followed in a simple monoxenic culture system using Ri T DNA-transformed carrot roots and… Expand
Fungal Growth Stimulation by CO(2) and Root Exudates in Vesicular-Arbuscular Mycorrhizal Symbiosis.
Transformed roots of carrot were used to determine the effects of root metabolites on hyphal development from spores of the vesicular-arbuscular mycorrhizal fungus Gigaspora margarita. Hyphal growth… Expand
6 Establishment of Vesicular-arbuscular Mycorrhiza in Root Organ Culture: Review and Proposed Methodology
Publisher Summary Vesicular-arbuscular mycorrhizal fungi are obligate biotrophs that have so far resisted all attempts to be cultivated axenically (in pure culture). This lack of independent growth… Expand
Flavonoids and arbuscular-mycorrhizal fungi.

Arbuscular mycorrhizal fungi (AMF) are ancient Zygomycetes forming the most widespread plant-fungus symbiosis. The regulation of this association is still poorly understood in terms of the… Expand
