Plants and Their Ectomycorrhizosphere: Cost and Benefit of Symbiotic Soil Organisms
نویسندگان
چکیده
“Most higher plants have no roots — they have mycorrhizae”. This is one of the most challenging statements in ecology (Begon et al. 1986). This entry holds true till now, since many publications corroborate the crucial importance of this mostly mutualistic symbiosis of tracheophytes with fungi.Mycorrhizae are no homogeneous entity. They differ in their modes of interaction with the plant and of nutrition. These features are used to distinguish mycorrhizal classes (Agerer 1993; Smith and Read 2008). One of the best known and most frequently studied mycorrhizal classes are ectomycorrhizae (ECM), which we focus on in this chapter.

An underground tale: contribution of microbial activity to plant iron acquisition via ecological processes.
BACKGROUND Iron (Fe) deficiency in crops is a worldwide agricultural problem. Plants have evolved several strategies to enhance Fe acquisition, but increasing evidence has shown that the intrinsic plant-based strategies alone are insufficient to avoid Fe deficiency in Fe-limited soils. Soil micro-organisms also play a critical role in plant Fe acquisition; however, the mechanisms behind their p...
متن کاملBiochemical profiling of microbes inhibiting Silver nanoparticles using symbiotic organisms
Silver nanoparticle therapeutics using symbiotic organisms can offer solutions to the current obstacles in antimicrobial therapies, because of cost-effective and eco-friendly properties over chemical and physical methods. In this study, we aim to synthesize silver nanoparticles using lichen (Parmotrema tinctorum) extract and evaluation of its antibacterial properties. Synthesized silve...
متن کاملAn overview of plant growth promoting rhizobacteria and their influence on essential oils of medicinal plants: a review article.
One of the important and necessary practices for improving nutrients availability in sustainable agriculture is using microorganisms. Beside the negative effects of chemical fertilizers on the soil and human health, plant growth promoting rhizobacteria are known as an alternative to supply the organic nutrients of plants during the past two decades. Enriching soil fertility by eco-friendly meth...
متن کاملHow plants communicate using the underground information superhighway.
The rhizosphere is a densely populated area in which plant roots must compete with invading root systems of neighboring plants for space, water, and mineral nutrients, and with other soil-borne organisms, including bacteria and fungi. Root-root and root-microbe communications are continuous occurrences in this biologically active soil zone. How do roots manage to simultaneously communicate with...

Biological nitrogen fixation (BNF) is carried out by free-living, non-symbiotic, associative and symbiotic nitrogen fixing bacteria, symbiotic fixers being the major contributors. LegumeRhizobium association being most effectively and widely studied is the major area of concern with regard to BNF technology. The symbiotic association between legumes and rhizobia is highly influenced by various ...
