Microbial co-operation in the rhizosphere.
TLDR
This article summarizes and discusses significant aspects of this general topic, including the analysis of the key activities carried out by the diverse trophic and functional groups of micro-organisms involved in co-operative rhizosphere interactions; a critical discussion of the direct microbe-microbe interactions which results in processes benefiting sustainable agro-ecosystem development. Expand
Unraveling mycorrhiza-induced resistance.
TLDR
Modulation of plant defense responses occurs, potentially through cross-talk between salicylic acid and jasmonate dependent signaling pathways, and may impact plant responses to potential enemies by priming the tissues for a more efficient activation of defense mechanisms. Expand
Management of Indigenous Plant-Microbe Symbioses Aids Restoration of Desertified Ecosystems
TLDR
It is demonstrated, in two long-term experiments in a desertified Mediterranean ecosystem, that inoculation with indigenous arbuscular mycorrhizal fungi and with rhizobial nitrogen-fixing bacteria not only enhanced the establishment of key plant species but also increased soil fertility and quality. Expand
Localized versus systemic effect of arbuscular mycorrhizal fungi on defence responses to Phytophthora infection in tomato plants.
TLDR
Evidence points to a combination of local and systemic mechanisms being responsible for this bioprotector effect of mycorrhizal symbiosis on tomato resistance to Phytophthora. Expand
Mycorrhizosphere interactions to improve plant fitness and soil quality
TLDR
It is concluded that microbial interactions in the rhizosphere of mycorrhizal plants improve plant fitness and soil quality, critical issues for a sustainable agricultural development and ecosystem functioning. Expand
Arbuscular mycorrhizas and biological control of soil-borne plant pathogens – an overview of the mechanisms involved
TLDR
Although the improvement of plant nutrition, compensation for pathogen damage, and competition for photosynthates or colonization/infection sites have been claimed to play a protective role in the AM symbiosis, information is scarce, fragmentary or even controversial, particularly concerning other mechanisms. Expand
Nitrate depletion and pH changes induced by the extraradical mycelium of the arbuscular mycorrhizal fungus Glomus intraradices grown in monoxenic culture.
TLDR
Results point towards an active uptake of nitrate by the extraradical mycelium of G. intraradices, probably coupled to a H+ -symport mechanism. Expand
Branched absorbing structures (BAS): a feature of the extraradical mycelium of symbiotic arbuscular mycorrhizal fungi
TLDR
The morphogenesis and cytological characteristics of ‘branched absorbing structures’ (BAS, formely named arbuscule-like structures, ALS), small groups of dichotomous hyphae formed by the extraradical mycelium of arbuscular mycorrhizal fungi, are described. Expand
The transcriptome of the arbuscular mycorrhizal fungus Glomus intraradices (DAOM 197198) reveals functional tradeoffs in an obligate symbiont.
TLDR
The first genome-wide analysis of the transcriptome from Glomus intraradices is reported, suggesting that the lack of a known sexual cycle in G. intrarodices is not a result of major deletions of genes essential for sexual reproduction and meiosis. Expand
GintAMT1 encodes a functional high-affinity ammonium transporter that is expressed in the extraradical mycelium of Glomus intraradices.
TLDR
Data suggest that GintAMT1 is involved in NH(4)(+) uptake by the extraradical mycelia from the surrounding media when it is present at micromolar concentrations, as revealed by [(14)C]methylammonium uptake experiments carried out in yeast. Expand
