Arbuscular mycorrhizal fungi (AMF) enhance the uptake of water and nutrients by host plants. In this study, we examined the response of six rice varieties from two ecotypes (three irrigated and three rainfed upland varieties) to AMF inoculation at five fertilizer levels, under continuous flooding (CF) and alternate wetting and drying (AWD) irrigati...

The integration of endomycorrhizal fungi into agricultural practices as inoculum offers the potential to improve plant productivity while reducing reliance on expensive chemical fertilizers, which are not only economically costly but also detrimental to the environment. Mycorrhizal fungi play a crucial role in facilitating plant access to essential...

Arbuscular mycorrhizal fungi (AMF) provide host plants with water and nutrients. Here, we investigated the response of six rice varieties from two ecotypes (three irrigated and three rainfed upland varieties) to inoculation at five fertilizer levels, under continuous flooding (CF) and alternate wetting and drying (AWD) irrigation in field condition...

The aim of this investigation was to evaluate the symbiotic performance of a collection of ten plant growth-promoting rhizobacteria (PGPR) strains on the growth and yield attributes of five groundnut varieties. The screening was conducted in the greenhouse using seeds of the varieties Essamay, Amoul Morom, 55-437, Fleur 11 and Sunu Gaal grown in 1....

Peanut is a key component of Senegal's predominantly cereal-based farming systems, but its production is challenged by low soil fertility. Rhizobial inoculation is a promising strategy to improve crop yield and reduce the use of chemical nitrogen fertilizers. The aim of this study was to isolate the most specific and effective bradyrhizobial strain...

The aim of this study was to isolate the most specific and effective arbuscular mycorrhizal fungi (AMF) for groundnut and to determine the degree of variability in the response of groundnut varieties to inoculation. The seeds of five varieties: 55-437, Fleur 11, Sunu Gaal, Amoul Morom, and Essamaay were inoculated individually with five AMF (Funnel...

Background Rhizosphere microbial communities are important components of the soil-plant continuum in paddy field ecosystems. These rhizosphere communities contribute to nutrient cycling and rice productivity. The use of fertilizers is a common agricultural practice in rice paddy fields. However, the long-term impact of the fertilizers usage on the...

Rhizosphere microbial communities are important components of the soil-plant-atmosphere continuum in paddy field ecosystems where they contribute to nutrient cycling and rice productivity. However, the rhizosphere microbial sensitivity to anthropic soil disturbance across plant growth stages remains little investigated. Here, we tracked the effects...

The intensification of biological processes coping with salt stress became a major issue to mitigate land degradation. The Sine-Saloum Delta in Senegal is characterized by salt-affected soils with vegetation dominated by salt-tolerant grass Sporobolus robustus and shrubs like Prosopis juliflora. Plant experiments in controlled conditions suggested...

Fungal communities associated with roots play a key role in nutrient uptake and in mitigating the abiotic and biotic stress of their host. In this study, we characterized the roots mycobiome of wild and cultivated pearl millet [ Pennisetum glaucum (L.) R. Br., synonym: Cenchrus americanus (L.) Morrone] in three agro-ecological areas of Senegal foll...

Arbuscular mycorrhizal (AM) fungi constitute promising biofertilizers for the deployment of a sustainable agriculture. However, the evaluation of mycorrhizal benefits in the field is poorly documented, notably in fruit tree orchards, and concerns exclusively growth performance and nutrition. Here, we evaluated the persistence of beneficial effects...

Pearl millet (Pennisetumglaucum (L.) R. Br) is a cereal grown in the driest tropical and subtropical regions of Africa and Asia. Thanks to its strong capacity to adapt to the dry tropical climate and low fertility soils, millet plays an important role in the food security of local populations in these regions. It is able to establish a mycorrhizal...

A wide program of fruit tree planting, notably jujube trees, has been implemented in the framework of the pan-African Great Green Wall (GGW) project to improve food security in arid and semiarid regions. However, the success of such initiatives is highly limited by a low tree growth and high tree mortality rates due to transplant shocks from tree n...

Arbuscular mycorrhizal fungi (AMF) play a major role as biofertilizer for sustainable agriculture. Nevertheless, it is still poorly documented whether inoculated AMF can successfully establish in field soils as exotic AMF and improve plant growth and productivity. Further, the fate of an exogenous inoculum is still poorly understood. Here, we pre-i...

Key message: The soil amendment with peanut shells (4, 6 or 8 t ha⁻¹) improves soil properties and growth ofSenegalia senegal(L.) Britton, Vachellia seyal (Delile) P.Hurter andProsopis juliflora(Swartz) DC seedlings on salty soils (86, 171, 257 mM NaCl). Context: Salinization causes the degradation of biological, chemical, and physical properties o...

Exotic trees are often planted to recover degraded lands. Inoculation with mycorrhizal fungi can improve their survival. Plant growth is partly dependent on the strain used, but little attention has been paid to the selection of mycorrhizal fungi. The aim of this study was to determine whether the growth of Casuarina equisetifolia L. (Johnson) is a...

Seedlings of S. robustus were exposed to increasing NaCl concentrations (0, 50, 100, 150, 200, 250, and 300 mM) for 50, 100, and 150 days, in greenhouse conditions. Total dry weight and salt tolerance index decreased gradually with increasing NaCl concentrations. The optimum growth of S. robustus (4.12 to 5.25 g · plant⁻¹) was obtained between 0 an...

Ectomycorrhizal networks may facilitate the establishment and survival of seedlings regenerating under the canopies of tropical forests and are often invoked as a potential contributor to monodominance. We identified ectomycorrhizal fungi in a monodominant Gilbertiodendron dewevrei (Fabaceae) rain forest in Cameroon, using sporocarps and ectomycorr...

Ziziphus mauritiana Lam., commonly known as jujube, is an important multipurpose fruit tree (e.g. fruits, fodder, medicine) for local inhabitants in the Sahel. Indian cultivars were introduced in its zone because of their precocity in fruiting and the larger size compared to the local ones. Furthermore, the orchards in its zone were found to be def...

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. Schussler. and Rhizoglomus intraradices (N.C. Schenck and G.S. Sm.) Sieverd., G.A. Silva and Oe...

We studied belowground and aboveground diversity and distribution of ectomycorrhizal (EM) fungal species colonizing Coccoloba uvifera (L.) L. (seagrape) mature trees and seedlings naturally regenerating in four littoral forests of the Guadeloupe island (Lesser Antilles). We collected 546 sporocarps, 49 sclerotia, and morphotyped 26,722 root tips fr...
