- Article scientifique
Article scientifique
Parentage assessment in the potato (Solanum tuberosum L.), based on a reliable characterization of DNA varieties, can be a useful tool in validating pedigree information as well as for assigning potential parents to orphan varieties. The approach suggested in this study was to use the genetic profiles obtained on 577 cultivars using a set of 17 polymorphic simple sequence repeats (SSR) markers in ...
Measurement of translesion synthesis by fluorescent capillary electrophoresis : 7,8-Dihydro-8-oxodeoxyguanosine bypass modulation by natural products

Article scientifique
Translesion synthesis (TLS) relies on a series of specialized DNA polymerases able to insert a base either correctly or incorrectly opposite a lesion on a DNA template strand during replication or post-repair synthesis. To measure the correct or mutagenic outcome of 7,8-dihydro-8-oxodeoxyguanosine (8-oxodG) bypass by TLS DNA polymerases, a capillary electrophoresis (CE) method with fluorescent label ...
Use of self-organizing map to analyze images of fungi colonies grown from Triticum aestivum seeds disinfected by ozone treatment

Article scientifique
We 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 ...

- Article scientifique
Article scientifique
Knowledge of both the genetic diversity and geographical distribution of animal genetic resources is a prerequisite for their sustainable utilization, improvement and conservation. The present study was undertaken to explore the current morphological variability within the sheep population in Benin as a prelude for their molecular characterization. From November 2018 to February 2020, 25 quantitative ...
Construction of a Novel Chimeric Dextransucrase Fused to the Carbohydrate-Binding Module CBM2a

Article scientifique
Lactic acid bacteria (LAB) have the potential to produce homoexopolysaccharides (HoPS).
Their health benefits and physicochemical properties have been the subject of extensive research.
The HoPS functional properties are determined by molecular weight, the type of glycosidic link ages, degrees of branching and chemical composition. The dextransucrases (DSases) produce a
kind of HoPS (dextrans), ...

- Article scientifique
Article scientifique
In order to investigate the pre-harvest contamination of maize plants by Fusarium species in Belgium, a three-year survey has been performed in five fields in which three hybrids differing in susceptibility to maize stalk rot were sampled at four different physiological stages. An extensive collection of 5,659 Fusarium isolates characterized at the species level was established during the 2005, 2006, ...
Effets des différentes balances hormonales sur la micropropagation du Cv. Hybride FHIA-01 (Musa sp.)

Article scientifique
Différentes balances hormonales ont été évaluées afin de proposer un milieu de prolifération permettant de multiplier efficacement l’hybride FHIA-01 en culture in vitro. Les principaux résultats obtenus sont: l’inhibition presque complète de la prolifération par la BAP; l’inhibition totale de l’enracinement par la concentration de 10 µM BAP+10 µM MemTR, l’amélioration de la prolifération moyenne de ...
Acclimatation de vitroplants de bananier (Musa sp.) en culture hydroponique : impact de différentes concentrations en cuivre sur la croissance des vitroplants

- Article scientifique
Article scientifique
Les contraintes dues au cuivre et les conséquences de son accumulation par les vitroplants de bananier pendant la phase d’acclimatation ont été étudiées en culture hydroponique.
Des doses de 0-100-500-1000 ppm de cuivre, sous forme de CuSO4, ont été ajoutées au milieu nutritif en culture hydroponique. A 1000 ppm CuSO4, les résultats obtenus ont mis en évidence des concentrations en cuivre élevées ...

Article scientifique
Les plants issus de la culture in vitro nécessitent une période d'acclimatation avant leur transfert au champ. Dans cette étude, la réponse des vitroplants de bananier aux fluctuations des températures et des quantités d'eau a été évaluée, lors de la phase d'acclimatation. Méthodologie et résultats : Dans le premier essai utilisant des vitroplants du bananier plantain, hybride FHIA-23 groupe AAAA, ...
Root Morphological Traits of Seedlings Are Predictors of Seed Yield and Quality in Winter Oilseed Rape Hybrid Cultivars

Article scientifique
The root system is responsible for soil resources acquisition. Hence, optimizing crop root characteristics has considerable implications for agricultural production. This study evaluated a panel of twenty-eight European modern cultivars of oilseed rape (Brassica napus L.) cultivated in laboratory and field environments. Root morphology was screened using a high-throughput hydroponic growth system ...
