Cosmopolitan plant root symbionts The aboveground lives of plants are only sustainable because the symbiotic soil fungi that encase their roots. These swap nutrients with plants, defend them from attack, and help withstand abrupt environmental changes. Out necessity, fungal in would appear to be restricted local certain species. Davison et al. , however, discovered some taxa globally distributed. How these underground have dispersed so widely remains a mystery; perhaps human farmers had...
ABSTRACT Here, we assessed the relative influence of wheat genotype, agricultural practices (conventional vs organic) and soil type on rhizosphere microbiome. We characterized prokaryotic (archaea bacteria) eukaryotic (fungi protists) communities in soils from four different countries (Cameroon, France, Italy, Senegal) determined if a core microbiome existed across these countries. The genotype had limited effect (2% variance) as majority microbial taxa were consistently associated to...
Salt stress in soils impacts grain crop yield. Soil amendment with biochar and arbuscular mycorrhizal alone has been analyzed to improve the growth of several crops under salinity stress. However, combined application fungi for remediation improvement productivity wheat are rarely discussed have remained unclear. Therefore, this experiment was performed investigate effect (150 g per each treated pot containing 3 kg soil) and/or (20 AMF inoculum 80% roots, 100–160 spores, extraradical hyphae...
Micronutrient deficiencies, particularly iron (Fe) and zinc (Zn) are prevalent public health issues in developing countries, with children under 5 years old breastfeeding women being the most affected Senegal. Agronomic approaches, including soil fertilization microbial biotechnology, used to alleviate these yet challenges persist due poor nutrient availability staple food crops like pearl millet (
Early leaf spot (ELS), caused by Passalora personata (syn. Cercospora arachidicola), is a highly damaging peanut disease worldwide. While there are limited sources of resistance in cultivated cultivars, wild relatives carry alleles for strong resistance, making them valuable strategic resource improvement. So far, only few diploid species have been utilized to transfer resistant cultivars. To mitigate the risk breakdown pathogens, it important diversify when breeding resistance. In this...
The overuse of agricultural chemicals such as fertilizer and pesticides aimed at increasing crop yield results in environmental damage, particularly the Sahelian zone where soils are fragile. Crop inoculation with beneficial soil microbes appears a good alternative for reducing chemical needs, especially small farmers. This, however, requires selecting optimal combinations varieties tested field conditions. In this study, we investigated response rice plants to arbuscular mycorrhizal fungi...
Pearl millet is able to withstand dry and hot conditions plays an important role for food security in arid semi-arid areas of Africa India. However, low soil fertility drought constrain pearl yield. One target address these constraints through agricultural practices or breeding root system architecture. In this study, order easily phenotype the field conditions, we developed a model predict length density (RLD) plants from intersection densities (RID) counted on trench profile conditions. We...
Bambara groundnut (Vigna subterranea) is a drought-tolerant legume in sub-Saharan Africa and well adapted to marginal agricultural lands. Its seeds have high nutritional value, owing their protein, fat, fiber, carbohydrate, vitamin, mineral element contents. Nevertheless, this crop still underutilized, not well-known has almost been ignored by researchers funding bodies. Meanwhile, offers opportunities for diversification great potential significantly contribute food security, especially the...
Abstract Fungal communities associated with roots play a key role in nutrient uptake and mitigating the abiotic biotic stress of their host. In this study, we characterized mycobiome wild cultivated pearl millet [ Pennisetum glaucum (L.) R. Br., synonym: Cenchrus americanus Morrone] three agro-ecological areas Senegal following rainfall gradient. We hypothesized that could serve as reservoir endophytes for millet. therefore analyzed soil factors influencing fungal community structure whether...
The response of microbial functional diversity as well its resistance to stress or disturbances caused by the introduction an exotic tree species, Acacia holosericea, ectomycorrhized not with Pisolithus albus, was examined. results show that this ectomycorrhizal fungus promotes drastically growth fast-growing species in field conditions after 7 years plantation. Compared crop soil surrounding A. holosericea plantation, associated symbiont, induced strong modifications functionalities...
L'arachide est cultivée par plus de 100 pays dans le monde. Les principaux producteurs sont la Chine et l'Inde qui fournissent 60 % production mondiale. L'Afrique assure 25 avec Nigéria, Sénégal Soudan principalement. Au Sénégal, les années 1960, culture l'arachide s'était développée comme rente (production d'huile tourteau) destinée à l'exportation une ouverture croissante sur marché mondial. Cette fut moteur du développement l'économie sénégalaise a assuré jusqu'à 80 des exportations...
Rhizosphere microbial communities are important components of the soil-plant continuum in paddy field ecosystems. These rhizosphere contribute to nutrient cycling and rice productivity. The use fertilizers is a common agricultural practice fields. However, long-term impact usage on at different developmental stages remains poorly investigated. Here, we examined effects (27 years) N NPK-fertilization bacterial archaeal community inhabiting three (tillering, panicle initiation booting) Senegal...
Aspergillus flavus is a cosmopolitan saprophytic fungus that infests several foodstuffs and associated with adverse effects in humans. In Senegal, significant losses of groundnut production are mainly due to contamination caused by this species. This study evaluated vitro antifungal activities Cyperus articulatus, rotundus Lippia alba essential oils against A. isolated from peanut seeds. Essential obtained hydrodistillation rhizomes the two species leaves L. were analyzed GC-DIF GC-MS. The...
The responses of the soil microbial community features associated to legume tree Acacia senegal (L.) Willd. including both arbuscular mycorrhizal fungal (AMF) diversity and bacterial functions, were investigated under contrasting environmental conditions. Soil samples collected during dry rainy seasons in two rainfall sites Senegal (Dahra Goudiry, arid semiarid zone, resp.). Soils taken from rhizosphere A. plantation natural stands comparison bulk soil. A multiple analysis revealed positive...
