Abstract Crop landraces have unique local agroecological and societal functions offer important genetic resources for plant breeding. Recognition of the value landrace diversity concern about its erosion on farms led to sustained efforts establish ex situ collections worldwide. The degree which these succeeded in conserving has not been comprehensively assessed. Here we modelled potential distributions eco-geographically distinguishable groups 25 cereal, pulse starchy root/tuber/fruit crops...
Inferring the diffusion history of many human-dispersed species is still not straightforward due to unresolved past human migrations. The centre diversification and routes migration autopolyploid clonally propagated greater yam, Dioscorea alata, one oldest edible tubers, remain unclear. Here, we address yam demographic dispersal using a worldwide sample.We characterized genome-wide patterns genetic variation genotyping by sequencing 643 accessions spanning four continents. First,...
Abstract Cowpea ( Vigna unguiculata (L.)) is an important crop for food security in Senegal; therefore, understanding the genetic diversity of local germplasm relevant improvement and maintenance era climate change. For this purpose, 15 microsatellite markers were used to estimate Senegalese cowpea germplasm, including 671 accessions grown eight regions 66 wild relatives intermediate forms (weedy) . cultivated , main expected heterozygosity (mHe) ranged between 0.317 (Fatick) 0.439 (South)....
Musa species are used traditionally for the management of many diseases. The study evaluated and compared anticholinesterase, anti-inflammatory, antioxidant, antidiabetic activities acuminata (Simili radjah, ABB) fruits leaves fractions characterized bioactive compounds using HPTLC-HRMS NMR. Leaf gave higher biological than fruit. Ethyl acetate fraction leaf had highest total phenolic content (911.9 ± 1.7 mg GAE/g) 2,2-diphenyl-1-picrylhydrazyl (DPPH·) scavenging activity (IC50, 9.0 0.4...
This study provides a physiological analysis of somatic embryogenesis in four elite cultivars date palms: Ahmar, Amsekhsi, Tijib, and Amaside, from the initial callogenesis to establishment proliferation embryogenic suspension cultures. Somatic embryos development vitro plants rooting were also studied. For each step, auxins cytokinins concentrations optimised. The primary leaf explants seedlings appeared highly dependent on genotype. Ahmar (80%) Amsekhsi (76%) callogenic, whereas Tijib...
Abstract In vitro culture is not only known for the mass propagation of medicinal plants, it can also be used to boost accumulation useful metabolites. This work was aimed at studying potential elicitation on antioxidant secondary metabolites in different Musa species accessions. Shoot cultures selected six spp. accessions were micropropagated Murashige and Skoog mineral-based medium, supplemented with indole-3-acetic acid 6-benzylaminopurine. Different temperatures (15, 20 26 °C), doses...
Abstract Development of core collection representing the diversity in entire germplasm creates a better access and enhanced utilization main thus allowing rapid evaluation crop improvement programs. Core collections are dynamic nature needs revisiting when additional information becomes available. In current study, an attempt was made to re-define previously developed yam ( Dioscorea spp) using 56 morphological traits. Information on acquired presence duplicates or mislabelled accessions...
Plant in vitro vegetative propagation using classical semi-solid culture medium is limited due to the low degree of automation, suboptimal nutrient availability and induced physiological stress which often reduce its efficiency. Temporary Immersion System (TIS) emerged as an innovative approach optimize eliminate drawbacks associated with conventional system micropropagation. In this study, both Dioscorea Musa spp. were subjected media, complete immersion shaking liquid media TIS RITA...
Abstract In vitro selection of drought-tolerant cassava varieties is essential for rapid breeding drought tolerance. The objectives this study were to determine the response three contrasting mannitol-induced stress establish its suitability in screening and examine relationships among growth parameters. Plantlets raised from nodal segments on Murashige Skoog (MS) medium containing 0 (control), 5, 10, 15, 20, 25 30 g/l mannitol. Variety CH 140 had highest survival explants frequency root...
Yam (Dioscorea spp.) is a monocotyledonous herbaceous vine plant grown in the tropics and subtropics. It multi-species with varied intra- interspecific ploidy levels. Of 600 species, 11 are cultivated supporting livelihood of over 300 million people. The paucity information on genomic constitution significant challenge to crop’s genetic improvement through crossbreeding. objective this study was investigate levels 236 accessions across six two wild species using chromosome counting, flow...
Apple (Malus × domestica Borkh. cv. Golden Delicious) trees were inoculated with fungal pathogens, corresponding either to an incompatible strain of Venturia inaequalis or non-host pathogens (Venturia pyrina, Alternaria brassicicola) in order characterize the regulation PR-10 genes these different situations relationship symptom development. Macro-and microscopic observations plant-fungus interactions revealed typical symptoms resistance V. and hypersensitivity (HR) on around 5 % leaves...
Cowpea (Vigna unguiculata) plays a key role in family farming systems Senegal. It makes an essential contribution to economic, nutritional and food security. Although it is crucial, little known about how farmers classify the diversity of local varieties or social practices associated with them. The aim this study characterize growing cowpea Surveys were conducted involving 335 rural living 37 villages, spread across seven regions that produce cowpea. An average ten randomly selected each...
To understand how the grassland use-value is creates, it necessary to study and model morphogenesis of plants. This focuses on one part morphogenesis, modelling foliar growth using mathematical function. The aim this evaluate fitting performance five functions kinetics. selected are: Logistic, Chanter, Gompertz, Hyperbola Beta Growth functions, data from a greenhouse experiment were used. These are kinetics leaf 1933 leaves 10 genotypes under 4 light quality treatments. recreates genetic...
