Dioecious species and arbuscular mycorrhizal symbioses: the case of Antennaria dioica.
2013
Sex-specific interactions with herbivores and pollinators have been observed in female and male plants of dioecious species. However, only a limited number of studies have revised sex-specific patterns in mycorrhizal symbiosis. To test whether female and male plants of Antennaria dioica differ in their relationship with arbuscular mycorrhizal (AM) fungi, we examined the temporal and spatial variation in AM fungi in female, male and non-reproductive A. dioica plants in three natural populations in Finland during flowering and after seed production. Our results are consistent with previous studies both under greenhouse and field conditions with the same species showing differences in AM colon…
Study of the impact of viticultural practices on arbuscular mycorrhizal fungi associated with vines
2021
Arbuscular mycorrhiza, a mutualistic symbiosis established between plants andarbuscular mycorrhizal fungi (AMF), providesmany ecosystem services such as improved soilstructure, increased plant growth and nutrition,and improved tolerance to biotic and abioticstresses. However, intensive agricultural practicesand the use of phytosanitary products as forexample herbicide and fungicides, have a strongimpact on communities of soil microorganisms,including arbuscular mycorrhizal fungi, as well ason biological mechanisms within the ecosystem.This thesis wotk is part of the European Biovineproject supported by the European Commissionthrough the CORE Organic Cofund.The aim of this research work was …
Augsnes faktoru ietekme uz arbuskulāro mikorizu pelēkajās kāpās rietumu Latvijas piekrastē
2015
Arbuskulārā mikoriza palīdz augiem izdzīvot dažādos neparastos apstākļos pie lieliem traucējumiem. Kas ietekmē mikorizu? Darbā ir apkopoti dati par mikorizas frekvenci, intensitāti un arbuskulu daudzumu augu saknēs, kā arī dati par augsni. Analizējot mikorizu, augu sugas un augsnes datu tiek aplūkota sakarība starp šiem trim faktoriem. No tā izriet, ka mikorizas esamību ietekmē, gan augsnes faktori, gan pats augs.

Effects of arbuscular mycorrhizal symbiosis on the nitrogen uptake of three durum wheat genotypes from two different organic sources

Soil inoculation with symbiotic microorganisms promotes plant growth and nutrient transporter genes expression in durum wheat
2015
In a field experiment conducted in a Mediterranean area of inner Sicily, durum wheat was inoculated with plant growth-promoting rhizobacteria (PGPR), with arbuscular mycorrhizal fungi (AMF), or with both to evaluate their effects on nutrient uptake, plant growth, and the expression of key transporter genes involved in nitrogen (N) and phosphorus (P) uptake. These biotic associations were studied under either low N availability (unfertilized plots) and supplying the soil with an easily mineralizable organic fertilizer. Regardless of N fertilization, at the tillering stage, inoculation with AMF alone or in combination with PGPR increased the aboveground biomass yield compared to the uninocula…
Nitrogen Availability Drives Mycorrhizal Effects on Wheat Growth, Nitrogen Uptake and Recovery under Salt Stress
2022
The arbuscular mycorrhizal (AM) symbiosis is generally considered effective in improving salt tolerance in plants; however, the advantages it offers can vary greatly depending on the context in which it occurs; furthermore, the mechanisms underlying these responses are still unclear. A study was conducted to investigate the role of nitrogen (N) availability on the effectiveness of AM symbiosis in durum wheat (Triticum durum Desf.) plants grown under salt stress. Plants were grown in pots in the absence or in presence of salt stress (soil electrical conductivity of 1.50 and 13.00 dS m−1, respectively), with or without AM fungi inoculation (Rhizophagus irregularis and Funneliformis mosseae), …

Suurin osa maalla elävistä putkilokasvilajeista ja -heimoista elää symbioosissa mykorritsasienten kanssa. Mykorritsatyyppejä on useita, ja näistä yleisin ja vanhin on arbuskelimykorritsasymbioosi, jossa Glomeromycota-sienet muodostavat arbuskelimykorritsaa (AM) kasvien juurien sisällä. Tämä kasvin ja sienen välinen tiivis suhde on molempia osapuolia hyödyttävä symbioosi. Toisenvarainen AM sieni on riippuvainen kasvin tuottamasta orgaanisesta hiilestä, ja vastapalveluksena sieni voi parantaa kasvin ravinteiden- ja vedenottokykyä, sekä suojata tätä taudinaiheuttajilta, tuhohyönteisiltä ja laiduntajilta, sekä parantaa kasvin kuivuudensietokykyä. Vaikuttamalla isäntäkasvien kasvuun ja resurssie…
Mycorrhizae in crop production
2007
International audience; It has been a revelation that, strictly speaking, most plants do not have roots but rather mycorrhizae, a fact that has had tremendous consequences on the life of plants and the evolution of soil-plant systems. The research on arbuscular mycorrhizal (AM) symbioses has been intensive over the past forty years and we have learned a lot on the physiology, biology, ecology, and genetics of the symbiosis and the fungi involved in it. Most important, it appeared that cropping systems could be more sustainable with the management of AM fungi and reduced reliance on agrochemicals. The extraradical mycelia of AM fungi are an essential link between the plants, which are the co…
