“…Increased root length and number can enhance absorption of more nutrients due to increased absorbing area resulting in improved plant growth (Marschner & Dell, 1994). Similar observations were made by other workers (Mugnier & Mosse, 1987;Varma et al, 2001). Inoculation of culture filtrate in case of grasses, trees and herbaceous sp.…”

The mycorrhiza plant partnership is the basic, essential and integral part of plant survival and growth. In the present investigation we are reporting the effect of culture filtrate of Piriformospora indica, a growth promoter and bioprotector fungus on Aristolochia elegans Mart. The culture filtrate of the fungus increased overall growth, biomass, and active ingredient-aristolochic acid in the leaves of plants. In untreated control plants, the overall growth was reduced. P. indica culture filtrate application increased root number, root length, and root dry weightby 28%, 98%, and 123% respectivelyin plants of Aristolochia. Also stem height and shoot length was enhanced by 43% and 155% respectively.There was increase in number of leaves by 79% and length of leaves by 36%. The increase in total biomass was 136%. The improvement in content of aristolochic acid in leaves was between7.6% and 28.8%in treated plants as against untreated control plants

“…Several mechanisms by which bacteria enhance mycorrhizae have been proposed, including removal of self-inhibitors from mycorrhizal spores (Mosse 1959 ;Daniels and Trappe 1980) or by the production of volatile chemicals that trigger spore germination (Azcon 1987 ;Mugnier and Mosse 1987). Another mechanism by which rhizobacteria might stimulate root colonization by mycorrhizae is by producing compounds that increase root cell permeability (Bowen 1980).…”

G . A ND R AD E, F .A .A . M. DE L EI J A N D J .M . LY NC H . 1998. Using undisturbed sandy loam soil cores heavily infested with mycorrhizae, the effects of the antibiotic-producing Pseudomonas fluorescens strain F113 and its non-antibiotic derivative Ps. fluorescens F113G22 on nodulation by introduced and indigenous Rhizobium were studied. Furthermore, the effects of the different microbial inocula on the colonization of the pea roots by mycorrhizae were studied. It was found that Ps. fluorescens F113 enhanced nodulation by Rhizobium fourfold, while the nodules produced were much larger and strongly pigmented (pink) compared with those in other treatments. The proportion of roots colonized by arbuscular mycorrhizae was not significantly affected by the different treatments.

“…Therefore, transformed roots have a quick, vigorous and homogenous growth in relative poor substrates without supplementation of hormonal substances. The negative geotropism of transformed roots facilitates contacts with hyphae of AM fungi (Bécard and Fortin, 1988;Mugnier and Mosse, 1987). Tepfer (1984) indicated they can survive for a long time without subculture, and Diop (1990) observed less contaminations in culture of transformed carrot roots due to their negative geotropism.…”

“…Chlamydospores of Glomus sp (Mosse and Hepper, 1975;Mugnier and Mosse, 1987) and non-sporocarpic azygospores of Gigaspora margarita (Bécard and Fortin, 1988;Bécard and Piché, 1989a;Diop et al, 1992) are obviously the preferred inoculum starter even though dormancy and strain mutation may occur under greenhouse conditions. The preference is due to availability of facility to recover, sterilize and to germinate these propagules.…”

Arbuscular mycorrhizal (AM) fungi are ecologically important for most vascular plants for their growth and survival. AM fungi are obligate symbionts. In recent years, there have been many attempts to cultivate in vitro. Some relevant results indicate efforts are not far from successful growth of AM fungi independent of a plant host. This paper describes the methods to cultivate root organs, and to select and purify AM fungal inocula (intraradical and extraradical forms). Axenic and monoxenic cultures of AM fungi are summarized and we propose a methodology to recover and achieve continuous culture of AM fungi without lost of infectivity. The in vitro systems have proved to be a valuable tool to study fundamental and practical aspects of AM symbiosis, complementing the in vivo experimental approaches. Finally, we give some proposals of in vitro AM researches to exploit more the potentialities of AM symbiosis.
