Challenges Associated with Byproducts Valorization—Comparison Study of Safety Parameters of Ultrasonicated and Fermented Plant-Based Byproducts

2020

In order to promote the efficient use of byproducts from the production of plant-based beverages, which still contain a large amount of nutritional and functional compounds, microbiological and chemical safety characteristics should be evaluated and, if needed, improved. Many challenges are associated with byproducts valorization, and the most important ones, which should be taken into account at the further steps of valorization, are biological and chemical safety. For safety improving, several technological treatments (biological, physical etc.) can be used. In this study, the influence of low-frequency ultrasonication (US) and fermentation with Lactobacillus casei LUHS210 strain, as phys…

Technical improvements for analysis of recalcitrant proteins by LC-MS : the mycorrhiza responsive membrane proteome as a case study

2012

Arbuscular mycorrhizas (AM) are widespread symbiotic associations between plant roots and AM fungi. Deep membrane alterations are the foremost morphological changes occurring in the host plant in response to AM symbiosis. Two-dimensional gel electrophoresis (2-DE) is the workhorse method in AM proteomics. Membrane proteins are under-represented in 2-DE because of their hydrophobicity, low abundance, and precipitation at their isoelectric point, thereby few are the identified membrane proteins involved in sustaining the AM symbiosis. Membrane proteomics is still challenging due to 2-DE related shortcomings, however latest trends and advancements in mass spectrometry (MS)-based quantitative p…

Diversité des champignons mycorhiziens à arbuscules en association avec Acacia saligna dans différentes régions de la Tunisie

2022

Acacia saligna, appelée également Acacia cyanophylla, est une fabacée arbustive originaire de l'Australie. Cette plante a une grande résilience et s’adapte facilement à de nombreux écosystèmes différents, ce qui lui confère une importance économique forte. De plus, elle forme plusieurs symbioses racinaires avec des microorganismes qui favorisent son développement et améliorent sa résistance vis à vis de différents stress biotiques et abiotiques :(i) les rhizobiums qui fixent l’azote atmosphérique et (ii) les champignons mycorhiziens à arbuscules (CMA) En Tunisie, aucune étude ciblant des microorganismes formant des symbioses racinaires associées à A. saligna n’a été effectuée. Ce travail s’…

Questing abundance of adult taiga ticks Ixodes persulcatus and their Borrelia prevalence at the north-western part of their distribution

2020

Background Because ixodid ticks are vectors of zoonotic pathogens, including Borrelia, information of their abundance, seasonal variation in questing behaviour and pathogen prevalence is important for human health. As ticks are invading new areas northwards, information from these new areas are needed. Taiga tick (Ixodes persulcatus) populations have been recently found at Bothnian Bay, Finland. We assessed seasonal variation in questing abundance of ticks and their pathogen prevalence in coastal deciduous forests near the city of Oulu (latitudes 64–65°) in 2019. Methods We sampled ticks from May until September by cloth dragging 100 meters once a month at eight study sites. We calculated a…

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), …

Can arbuscular mycorrhizal fungi enhance plant nitrogen capture from organic matter added to soil?

The role of symbiotic arbuscular mycorrhizal fungi (Glomeromycota) in roots of the host plant Deschampsia flexuosa in vegetation succession of inland…

2013

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…

Nutrition et protection de la vigne par la symbiose mycorhizienne à arbuscule

2021

National audience; La vigne, comme la majorité des espèces de plante d’intérêt agronomique, forme une symbiosemutualiste avec les Champignons Mycorhiziens à Arbuscules (CMA). En contrepartie deproduits issus de la photosynthèse, les CMA soutiennent leur(s) plante(s) hôte(s) dansl’acquisition de nutriments et la lutte contre leur(s) pathogène(s). En tant que biofertilisants, cessymbiontes obligatoires représentent une alternative de choix à l’égard des pratiques agricolesconventionnelles pour le développement d’une agriculture, et notamment d’une viticulturedurable. Les échanges entre les deux partenaires sont permis par la mise en place de structuresfongiques spécialisées appelées arbuscule…
