African Journal of Biotechnology, Vol. 15, n°45. Pan-genome analysis of Senegalese and Gambian strains of Bacillus anthracis [texte imprimé] / Mbaye Mbengue, Auteur ; Fatou Tall Lo, Auteur ; Alpha Amadou Diallo, Auteur ; Y. S. Ndiaye, Auteur ; D.

| Mots-clés : | Souche sénégalaise, Bacillus anthracis, Souche sénégalaise, , pan-génome, pathogène | Index. décimale : | L730-Maladie des animaux | Résumé : | Bacillus anthracis is the causative agent of anthrax, and it is classified as “category A” biological weapon. There were six available complete genomes (A0248, Ames, Ames Ancestor, CDC684, H0491 and Sterne). Here, one Gambian and two Senegalese strains (Gmb1, Sen2Col2 and Sen3) were added. In this work, the pan-genome of B. anthracis was studied based on nine strains and using bioinformatics tools as Cluster of Orthologous Groups (COG) and Kyoto Encyclopedia of Genes and Genomes (KEGG). Thereafter, B. anthracis pan-genome having 2893 core genes and 85 accessory genes was estimated. With Mauve method, the pan-genome of B. anthracis was verified and it was found to be very narrow and clonal. To have confidence in this study, different tools were used to compare and validate the results. All of the tools yielded the same results; the addition of the Senegalese and Gambian strains did not change the nature of the B. anthracis pan-genome (2893 core genes and 85 accessory genes), which had a core/pan-genome ratio of 99%. The closed nature of the pan-genome of B. anthracis (the core genome) represents 99% of the pan-genome size. The hypothesis that B. anthracis had a closed pan-genome was hereby validated. |

African Journal of Biotechnology, Vol 14, N°39. Effect of arbuscular mycorrhizalfungal inoculation on growth, and nutrien tuptake of the two grass species, Leptochloa fusca (L.) Stapf and Sporobolus robustus Kunth, under greenhouse conditions. [texte imprimé] / F Fall, Auteur ; D. Diouf, Auteur ; I. Ndoye, Auteur ; C. Ndiaye, Auteur ; A. Kane, Auteur ; Bâ A.M., Auteur . - 2015 . - pp2770-2776. Langues : Anglais ( eng) Catégories : | FORESTERIE
| Mots-clés : | Grass species, symbiosis, mycorrhizal dependency, mineral nutrition. | Index. décimale : | K30-Génétique et amélioration des plantes forestiéres | Résumé : | The aim of our work was to assess the effect of inoculation with three arbuscular mycorrhizal fungi (AMF) (Rhizoglomus aggregatum (N.C. Schenck and G.S. Sm.) Sieverd., G.A. Silva and Oeh., Funneliformis mosseae (T.H. Nicolson and Gerd.) C. Walker and A. Schüssler. and Rhizoglomus intraradices (N.C. Schenck and G.S. Sm.) Sieverd., G.A. Silva and Oehl.), and a mixed inoculum of these AMF on root colonization, biomass production, mycorrhizal dependency (MD) and shoot mineral contents of two salt tolerant grasses Leptochloa fusca L. Stapf and Sporobolus robusts Kunth. After four months of growth in a sterilized soil and greenhouse conditions, grasses inoculated with AMF showed significantly higher total biomass production than non-inoculated seedlings. MD and shoot mineral contents (especially P) varied with AMF host plants. Maximum values of MD (13%) were observed in L. fusca and S. robustus seedlings when inoculated with R. intraradices and F. mosseae, respectively. Only P contents were higher in the S. robustus/mixed-AMF combinations than the other treatments. These results demonstrate the potential benefits in our experimental conditions of AM inoculation for improving growth and P acquisition particularly in the L. fusca/ F. mosseae and S. robustus/mixed-AMF combinations. |
