TLDR
The trehalose content of mycorrhizal roots increased concurrently with the course of fungal infection, and decreased both upon P fertilization and light deprivation, while the content of total soluble carbohydrates decreased only upon light deprivation.About:

Journal ArticleDOI
Arbuscular mycorrhizal fungi in alleviation of salt stress: a review.
TL;DR: This review gives useful benchmark information for the development and prioritization of future research programmes and identifies certain lesser explored areas such as molecular and ultra-structural changes where further research is needed for better understanding of symbiosis with reference to salt stress.
Journal ArticleDOI
Carbon uptake and the metabolism and transport of lipids in an arbuscular mycorrhiza
TL;DR: Labeling patterns observed in lipids and carbohydrates after substrates were supplied to the mycorrhizal roots or the extraradical mycelium indicated that 13C-labeled glucose and fructose are effectively taken up by the fungus within the root and are metabolized to yield labeled carbohydrates and lipids.
Journal ArticleDOI
Microbial amelioration of crop salinity stress
TL;DR: This review aims to evaluate the beneficial effects of soil biota on the plant response to saline stress, with special reference to phytohormonal signalling mechanisms that interact with key physiological processes to improve plant tolerance to the osmotic and toxic components of salinity.
Journal ArticleDOI
Partitioning of intermediary carbon metabolism in vesicular-arbuscular mycorrhizal leek
Yair Shachar-Hill,Philip E. Pfeffer,David D. Douds,Stanley F. Osman,Landis W. Doner,R. G. Ratcliffe +5 more
TL;DR: Nuclear magnetic resonance spectroscopy with [13C]glucose labeling in vivo and in extracts to examine leek roots colonized by Glomus etunicatum as well as germinating spores implicate glucose as a likely substrate for vesicular-arbuscular mycorrhizal fungi in the symbiotic state.
Journal ArticleDOI
Mycorrhizal sink strength influences whole plant carbon balance of Trifolium repens L
TL;DR: Increased C allocation to roots of M plants was associated with a stimulation of the activities of cell wall and cytoplasmic invertases and of sucrose synthase in roots colonized by VA fungi, which may provide the mechanism enabling increased partitioning of carbohydrate both to the M root system and the fungal symbiont.

Improved procedures for clearing roots and staining parasitic and vesicular-arbuscular mycorrhizal fungi for rapid assessment of infection.
J.M. Phillips,D. S. Hayman +1 more
TL;DR: To improve stain penetration and clearing in whole mycorrhizal roots of onion and other host plants, and in roots infected by other fungi, the following two procedures are developed, which give deeply stained fungal structures which show distinctly against the outlines of the cells in the cortex of intact roots.
Journal ArticleDOI
An evaluation of techniques for measuring vesicular arbuscular mycorrhizal infection in roots
TL;DR: The standard error of four methods of assessment based on observations of stained root samples either randomly arranged in a petri dish or mounted on microscope slides are calculated.
Journal ArticleDOI
Plant growth responses to vesicular-arbuscular mycorrhiza
TL;DR: Data show clearly that different endophytes vary enormously in their symbiotic effectiveness at different soil pHs, even where they did not enhance plant growth in studies of this nature.
Book ChapterDOI
The Metabolism of α,α-Trehalose*
TL;DR: In this paper, the role of trehalose in the growth of Mycobacterium smegmutis under various conditions of nitrogen limitation was examined, and the results of labeling studies suggested that the free trehaloses in these cells may be utilized for purposes except as an energy reserve, whereas glycogen is probably stored mainly as a reserve.
Journal ArticleDOI
Regulation of trehalose mobilization in fungi.
TL;DR: The inhibition of regulatory trehalase by nitrogen sources in the presence of glucose and the induction of fungal spore germination by heat shock are studied.
