In Vitro Dual Culture of Polymyxa betae in Agrobacterium rhizogenes Transformed Sugar Beet Hairy Roots in Liquid Media
23 juin 2011, HE CondorcetArticle scientifique"Polymyxa betae is a soil-borne protist and an obligate parasite of sugar beet that transmits the beet necrotic yellow vein virus. Sugar beet hairy roots, transformed by Agrobacterium rhizogenes, were inoculated with surface-sterilized root fragments infected by P. betae. After 10 wk in a liquid medium, typical structures of P. betae were observed in this in vitro system. This first in vitro culture ... -

Molecular interactions between sugar beet and Polymyxa betae during its life cycle
20 janvier 2014, HE CondorcetArticle scientifique"Polymyxa betae is a biotrophic obligate sugar beet parasite that belongs to plasmodiophorids. The infection of sugar beet roots by this parasite is asymptomatic, except when it transmits Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania. To date, there has been little work on P. betae–sugar beet molecular interactions, mainly because of the obligate nature of the parasite and ... -

Systemic resistance induced by Bacillus lipopeptides in Beta vulgaris reduces infection by the rhizomania disease vector Polymyxa betae
19 décembre 2012, HE CondorcetArticle scientifiqueThe control of rhizomania, one of the most important diseases of sugar beet caused by the Beet necrotic yellow vein virus, remains limited to varietal resistance. In this study, we investigated the putative action of Bacillus amylolequifaciens lipopeptides in achieving rhizomania biocontrol through the control of the virus vector Polymyxa betae. Some lipopeptides that are produced by bacteria, ... -
Not in your usual Top 10 : protists that infect plants and algae
11 juillet 2017, HE CondorcetArticle scientifiqueFungi, nematodes and oomycetes belong to the most prominent eukaryotic plant pathogenic organisms. Unicellular organisms from other eukaryotic lineages, commonly addressed as protists, also infect plants. This review provides an introduction to plant pathogenic protists, including algae infecting oomycetes, and their current state of research. -

13 février 2018, HE CondorcetArticle scientifique"The world potato is facing major economic losses due to disease pressure and environmental concerns regarding pesticides use. This work aims at addressing these two issues by isolating indigenous bacteria that can be integrated into pest management strategies." Extrait de l'abstract -
Plant Microbiota Beyond Farming Practices: A Review
29 mars 2021, HE CondorcetArticle scientifique"Being able to engineer microbial communities in ways that benefit crop health and growth will help decrease the number of chemical inputs required. Against this background, this review explores the impacts of agricultural practices on soil- and plant-associated microbiomes, focusing on plant growth-promoting microorganisms from a metagenomic perspective." Extrait de l'abstract -
Aspergillus spp. and Bacillus spp. as Growth Promoters in Cotton Plants Under Greenhouse Conditions
13 août 2021, HE CondorcetArticle scientifique"This study aimed to verify the potential of three Aspergillus and Bacillus species as growth promoters in cotton plants under greenhouse conditions. The experiment was conducted with a completely randomized design with seven treatments (six microorganisms plus one control) and five replicates until the flowering stage at 70 days after emergence." Extrait de l'abstract -
Les analyses en viticulture : un accompagnement du début du projet jusqu'au produit fini
11 janvier 2022, HE CondorcetArticle scientifique[Disponible sur le site du sillon belge] Le métier de vigneron implique la maîtrise de diverses disciplines. En effet, celui-ci doit être performant tant sur le terrain, pour mener à bien la conduite de ses parcelles de vignes, qu’en cave (chai) pour la transformation de ses raisins via de très nombreux processus de vinification différents, ainsi qu’à la vente et la commercialisation de ses produits -
Oilseed Rape Cultivars Show Diversity of Root Morphologies with the Potential for Better Capture of Nitrogen
14 décembre 2021, HE CondorcetArticle scientifiqueThe worldwide demand for vegetable oils is rising. Oilseed rape (Brassica napus) diversifies cereal dominated crop rotations but requires important nitrogen input. Yet, the root organ is offering an untapped opportunity to improve the nitrogen capture in soil. This study evaluates three culture systems in controlled environment, to observe root morphology and to identify root attributes for superior ... -
Valorization of sugar beet pulp to value-added products: A review
février 2022, HE CondorcetArticle scientifiqueThe processing of sugar beet in the sugar production industry releases huge amounts of sugar beet pulp as waste which can be considered a valuable by-product as a source of cellulose, hemicellulose, and pectin. Valorization of sugar beet pulp into value added products occurs through acid hydrolysis, hydrothermal techniques, and enzymatic hydrolysis. Biochemical conversion of beet pulp into simple ... -
Valorization of dairy waste and by-products through microbial bioprocesses
28 novembre 2021, HE CondorcetArticle scientifiqueWaste is an inherent and unavoidable part of any process which can be attributed to various factors such as process inefficiencies, usability of resources and discarding of not so useful parts of the feedstock. Dairy is a burgeoning industry following the global population growth, resulting in generation of waste such as wastewater (from cleaning, processing, and maintenance), whey and sludge. These ... -
Development and application of a quantitative real-time PCR assay for rapid detection of the multifaceted yeast Kazachstania servazzii in food.
avril 2017, CARAHArticle scientifiqueThe beneficial contributions of Kazachstania servazzii are well-established in various food processes. This yeast also contributes in the spoilage of finished packaged food due to abundant gas production. In particular, an occurrence of K. servazzii was recently positively correlated with the formation of severe package swelling of some prepared fresh pizzas. To circumscribe this concern, a quantitative ... -
Effects of Chemopreventive Natural Compounds on the Accuracy of 8-oxo-7,8-dihydro-2′-deoxyguanosine Translesion Synthesis
08 juillet 2021, HE CondorcetArticle scientifiqueTranslesion synthesis is a DNA damage tolerance mechanism that relies on a series of specialized DNA polymerases able to bypass a lesion on a DNA template strand during replication or post-repair synthesis.

Use of self-organizing map to analyze images of fungi colonies grown from Triticum aestivum seeds disinfected by ozone treatment
16 octobre 2012, HE CondorcetCARAHArticle scientifiqueWe submitted to ozone treatment Triticum aestivum (common wheat) seeds severely contaminated by fungi. Fungi colonies developed when seeds were placed over malt agar medium in Petri dishes; Fusarium sp. and Alternaria sp. were identified. However, conventional colonies counting did not allow a clear assessment of the effect of ozone disinfection. We thus used self-organizing maps (SOMs) to perform ...
