PREMISE OF THE STUDY Recent analyses employing up to five genes have provided numerous insights into angiosperm phylogeny, but many relationships have remained unresolved or poorly supported. In the hope of improving our understanding of angiosperm phylogeny, we expanded sampling of taxa and genes beyond previous analyses. METHODS We conducted two primary(More)
C. Franche1,*, D. Diouf1, Q.V. Le1, D. Bogusz1, A. This capacity for rapid growth comes from a symbiotic association with an actinomycete of the genus Frankia, N’Diaye1, H. Gherbi1, C. Gobé1 and E. Duhoux1,2 1Physiologie Cellulaire et Moléculaire des Arbres which allows A. verticillata to fix dinitrogen in root nodules, so-called actinorhizae (Benson and(More)
AIMS We characterized phenotypically and genotypically root-nodulating bacteria associated with Acacia senegal (L.) Willd. isolated from the soils surrounding A. senegal trees in the dry land area of Senegal. METHODS AND RESULTS The phenotypical and genotypical characterizations we carried out showed a high diversity of A. senegal root-nodulating(More)
Genetic diversity in local cowpea varieties and breeding lines from Senegal were studied using random amplified polymorphic DNA (RAPD) and microsatellite (SSR) techniques. Among the 61 RAPD primers used, twelve show polymorphism. Fifteen of the 30 microsatellite primer pairs were polymorphic, detecting one to nine alleles per locus. The RAPD and SSR data(More)
AIMS To assess the phenotypic, symbiotic and genotypic diversity scope of Mesorhizobium spp. strains associated with Acacia seyal (Del.) isolated from different agro-ecological zones in Senegal, and uses of susceptible microbial inoculum in a reafforestation process. METHODS AND RESULTS A polyphasic approach including phenotypic and genotypic techniques(More)
Trees belonging to the Casuarinaceae and Betulaceae families play an important ecological role and are useful tools in forestry for degraded land rehabilitation and reforestation. These functions are linked to their capacity to establish symbiotic relationships with a nitrogen-fixing soil bacterium of the genus Frankia. However, the molecular mechanisms(More)
After decades of research on cowpea, significant amount of omics datasets are available and useful in understanding the genetic relationship between Vigna unguiculata ssp. unguiculata and other species belonging to the same genus as well as its genetic variation. Besides, the development of genetic map allowed the chromosome localization of molecular(More)
The symbiotic association between certain plants and microorganisms plays an important role in soil fertilization, and improves their growth and mineral nutrition. Microorganisms implicated in this symbiotic interaction are from two groups: bacteria and fungi. The bacteria group is implicated on nitrogen fixation (for review see Pawlowski and Bisseling,(More)
The matK gene has been among the most useful loci for resolving plant phylogenetic relationships at different evolutionary time-scales, but much less is known about the phylogenetic utility of the flanking trnK intron, especially for deep level phylogenetics. We compared the relative performance of matK and trnK intron regions for resolving the(More)
Sesame is an important oilseed crop mainly grown in inclement areas with high temperatures and frequent drought. Thus, drought constitutes one of the major constraints of its production. The AP2/ERF is a large family of transcription factors known to play significant roles in various plant processes including biotic and abiotic stress responses. Despite(More)
