“…From an economic point of view, tiger nut is described as an underutilized African crop with high potential for development [20]. Because of its ecological plasticity and its invasive capacity, this plant is considered as a weed or a crop depending on the context [18]. In West Africa, the tubers are often part of the diet as they are cheap, available all the year around, and with nutritional benefits [20].…”

Tiger nut (Cyperus esculentus) is a tuber that can be consumed raw or processed into beverages. Its nutritional composition shows a high content of lipid and dietary fiber, close to those of nuts, and a high content of starch, like in other tubers. Tiger nuts also contain high levels of phosphorus, calcium, and phenolic compounds, which contribute to their antioxidant activity. From those characteristics, tiger nuts and derived beverages are particularly relevant to limit food insecurity in regions where the plant can grow. In Europe and United States, the tiger nut derived beverages are of high interest as alternatives to milk and for gluten-free diets. Fermentation or addition of probiotic cultures to tiger nut beverages has proven the ability of lactic acid bacteria to acidify the beverages. Preliminary sensory assays concluded that acceptable products are obtained. In the absence of pasteurization, the safety of tiger nut-based beverages is not warranted. In spite of fermentation, some foodborne pathogens or mycotoxigenic fungi have been observed in fermented beverages. Further studies are required to select a tailored bacterial cocktail which would effectively dominate endogenous flora, preserve bioactive compounds and result in a well-accepted beverage.

“…Cyperus esculentus (commonly known as yellow nutsedge or tiger nut) is a grass-like perennial herb that belongs to the sedge family Cyperaceae that is widely distributed in almost all tropical, subtropical and temperate zones [ 1 ]. C. esculentus is currently found a special untraditional underground crop since it has relatively high yield (ranging from 4.5 to 12 t·ha − 1 ) [ 2 ] and its storage tubers accumulate high levels of all three storage reserves: up to 40% starch, 35% oil, and 20% soluble sugars [ 3 – 6 ], which offers it high energy with ~ 400–450 kcal/100 g [ 6 ].…”

BackgroundCyperus esculentus is unique in that it can accumulate significant amounts of oil, starch and sugar as major storage reserves in tubers with high tuber yield and therefore considered as a novel model to study carbon allocation into different storage reserves in underground sink tissues such as tubers and roots. Sucrose (Suc) plays a central role in control of carbon flux toward biosynthesis of different storage reserves; however, it remains unclear for the molecular mechanism underlying Suc metabolism in underground oil-rich storage tissues. In the present study, a comprehensive transcriptome analysis of C. esculentus oil tuber compared to other plant oil- or carbohydrate-rich storage tissues was made for the expression patterns of genes related to the Suc metabolism.ResultsThe results revealed some species-specific features of gene transcripts in oil tuber of C. esculentus, indicating that: (i) the expressions of genes responsible for Suc metabolism are developmentally regulated and displayed a pattern dissimilar to other plant storage tissues; (ii) both of Suc breakdown and biosynthesis processes might be the major pathways associated with Suc metabolism; (iii) it was probably that Suc degradation could be primarily through the action of Suc synthase (SUS) other than invertase (INV) during tuber development. The orthologs of SUS1, SUS3 and SUS4 are the main SUS isoforms catalyzing Suc breakdown while the vacuolar INV (VIN) is the leading determinant controlling sugar composition; (iv) cytosolic hexose phosphorylation possibly relies more on fructose as substrate and uridine diphosphate glucose pyrophosphorylase (UGP) plays an important role in this pathway; (v) it is Suc-phosphate synthase (SPS) B- and C-family members rather than SPS A that are the principal contributors to SPS enzymes and play crucial roles in Suc biosynthesis pathway.ConclusionsWe have successfully identified the Suc metabolic pathways in C. esculentus tubers, highlighting several conserved and distinct expressions that might contribute to sugar accumulation in this unique underground storage tissue. The specific and differential expression genes revealed in this study might indicate the special molecular mechanism and transcriptional regulation of Suc metabolism occurred in oil tubers of C. esculentus.Electronic supplementary materialThe online version of this article (10.1186/s12870-018-1363-9) contains supplementary material, which is available to authorized users.

“…Le souchet (Cypérus esculentus L.) est une plante herbacée de la famille des cypéracées, originaire de la Méditerranée et de l'Est de l'Asie (Aoua et al, 2008). Il a été domestiqué et utilisé comme plante alimentaire presque dans tous les continents (Afrique, Sud de l'Europe, Asie et Nord-Est des USA et du Canada) du monde (Dodet, 2006;Defelice, 2002;De Castro et al, 2015). Cette plante est cultivée pour ses tubercules qui ont une bonne valeur nutritionnelle parce qu'elle contiennent des quantités élevées de matière grasse, de sucre, d'éléments minéraux et de vitamines (Aoua et al, 2008).…”

“…Les mêmes constats sont faits au Benin par Oloukoi et al (2019) qui rapportent que les principales mutations pluviométriques observées par les paysannes sont le démarrage tardif, l'arrêt précoce et l'irrégularité des pluies dont les conséquences se traduisent par la baisse de la productivité et du rendement agricole. C'est le cas du département du Mayo-Danay dont la mauvaise répartition et les trous pluviométriques au moment de floraison, et surtout aux stades critiques des plantes ont engendré les perturbations climatiques (soient 647 mm, 837,85 mm et 774,87 mm respectivement pour les années de 2015de , 2016de et 2017de (ACEFA, 2018). Suite à cette perturbation pluviométrique, des baisses des rendements de certaines spéculations ont été enregistrées.…”

La valorisation de certaines espèces sous-utilisées constitue des moyens palliatifs de la diversification des cultures dans certaines localités de l’Extrême-Nord. Plus spécifiquement, l’absence des connaissances sur les méthodes culturales de la culture de souchet (Cypérus esculentus L.) constitue un frein de sa production. Face à cette situation, une étude été menée dans la plaine du Mayo-Danay (Danay-vokgora) afin de transférer le paquet technologique (itinéraire technique) de production de cette culture aux producteurs en vue de substituer les cultures sensibles à la variabilité et au changement climatique. Une parcelle de démonstration (Champ Ecole Paysan (CEP)) de quatre accessions de souchet (Cyperus esculentus L.) a été mise en place. Les opérations culturales ont été mise en oeuvre dans le dispositif en split plot comprenant les blocs de placettes complètement randomisées. La densité de semis et les accessions comportant quatre modalités chacun et répétées quatre fois ont été appliquées et contrôlées. L’issu des résultats révèlent qu’il n’existe pas des effets des densités de semis sur les rendements moyens en t/ha de souchet au seuil de 5% de signification. Par contre, les accessions « c= glazay » et « d= wéchéché » se sont différenciées avec les meilleurs rendements moyens en t/ha. Bien que l’accession « c= glazay » fasse l’objet du choix de préférence des bénéficiaires de ladite localité, la comparaison des quantités nécessaires et des productivités marginales des inputs de production de souchet (Cyperus esculentus L.) ont montré qu’il serait avantageux de produire avec l’accession « d= wéchéché », car avec la meilleure combinaison des inputs de production, sa productivité marginale (73,09 FCFA) serait plus profitable pour l’unité additionnelle relative au coût de location de la parcelle. De ce fait, il est important d’évaluer cette pratique culturale pour mieux apprécier le degré d’adoption de l’innovation relative à l’itinéraire technique de la culture de souchet dans la localité de Danay-vokgora.Mots clés: Valorisation, Souchet, Rendement, Danay-vokgoro, Soudano-sahélienne. English Title: Valorization of four accessions of tigernut (Cyperus esculentus L.): a good option of cultural diversification for the producers of the locality of danay-vokgora (Mayo-danay) in sudano-sahelien zone CameroonThe development of some underutilized species is a palliative means of crop diversification in some communities in the Far North. More specifically, the lack of knowledge about the cultivation methods of Tigernut culture (Cyperus esculentus L.) is a hindrance to its production. Faced with this situation, a study was conducted in the Mayo-Danay plain (Danay-vokgora) in order to transfer the technological package (technical practice) of production of this crop to producers in order to replace crops sensitive to variability and climate change. A demonstration plot (Field School Peasant (CEP)) of four accessions of Tigernut (Cyperus esculentus L.) has been set up. To do this, the implementation of the operations was conducted in the experimental split plot including randomized completely block design. Seedling density and accessions with four modalities each and repeated four times were applied and controlled. At the end of study, the results show that at 5% level of the significance, the effects of planting densities do not influence on average yields in t/ha of Tigernut (Cyperus esculentus L.). On the other hand, "c = glazay" and "d=wéchéché" accessions of Tigernut (Cyperus esculentus L.) differed by presenting best average yields in t/ha. While "c = glazay"accession is subject to the choice of preference beneficiaries to Danay-vokgora locality (Mayo-Danay), but the comparison of quantities needed and the marginal productivity of the production of the accessions of the Tigernut (Cyperus esculentus L.) has shown that it would advantageous to produce with the "d=wéchéché" accession, because with the best combination of inputs, her marginal productivity would be more profitable for an additional unit of 73.09 FCFA for the renting cost of the parcel. Therefore, it is important to evaluate this farming practice to better appreciate the degree of adoption of innovation related to the technical practice of Tigernut (Cyperus esculentus L.) culture in the locality of Danay-vokgora.Keywords: Valorization, Nutgrass, Yield, Danay-vokgoro, Sudano-sahelien.
