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, ... -

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 -

Il est disponible de la page 118 à la page 134. Résumé : Dans l’enseignement supérieur en Belgique francophone, nombreux sont les enseignants et les chercheurs à débattre autour de la (non) maîtrise de la langue française par les étudiants, mais aussi à se poser la question de l’efficacité des ... -
Les mécanismes de défense chez les cépages interspécifiques
21 janvier 2022, CARAHArticle scientifique[Disponible sur le site du Sillon Belge] L’espèce de vigne domestiquée en Europe depuis plus de 6000 ans avant notre ère est Vitis vinifera. Cependant, bien d’autres espèces existent dans le monde, réparties sur l’ensemble du globe terrestre : V. labrusca, V. berlandieri, V. riparia, V. amurensis… -
Les outils d'aide à la décision (OAD) : lutter contre les principales maladies de la vigne
17 janvier 2022, CARAHArticle scientifique[Disponible sur le site du sillon belge] L’acronyme OAD signifie Outil d’Aide à la Décision. Les OAD sont des outils précieux qui sont de plus en plus utilisés en agriculture. Ils décrivent des situations phytosanitaires de présence, développement et de prévision de bioagresseurs et sont accompagnés de règles de décision permettant de guider l’utilisateur vers la décision d’intervenir ou non. -
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 ... -
