Studies conducted in the delta and lower valley of Senegal river have demonstrated through ethnobotanical surveys, the importance of Nymphaea lotus L. and Nymphaea micrantha guill. et Perr in the diet and in the pharmacopoeia. The seeds are used with good appreciation by the indigenous population as a welding food. But studies addressing their biochemical and nutritional aspects are still very rare in the literature. This study was initiated in order to fill this gap and allow a better appreciation of the nutritional and energetic potentialities of these seeds. For this purpose, seeds were collected in effluent from the Senegal River, dried in the shade and put into three different batches: a batch of red seeds of N. lotus, a batch of Black seeds of N. lotus and a batch of seeds of N. micrantha. The biochemical analyses gave their moisture content (9.17% ± 0.2% to 13.36% ± 3.46%), aw (0.46% to 0.71%), protein (7.90% ± 1.25% to 8.24% ± 0.5%), lipid (2.32% ± 0.45% to 4.29% ± 1.0%), carbohydrate (74.49% ± 0.9% and 77.66% ± 1.65%), mineral matter (1.77% ± 0.06% to 2.55% ± 0.08%). All three types of seeds have high levels of potassium (481.10% ± 17.62% to 770.81% ± 42.33%), magnesium (312.71% ± 14.08% to 518.67% ± 15.23%) and calcium (188.81% ± 8.52% to 296.52% ± 16%. Their energy values (350.54 ± 15.21 kcal/100g to 375.7 ± 3.48 Kcal/100g), are closed to other cereals consumed in the human diet in Senegal. Therefore, these seeds offer the opportunity to diversify the diet in the delta and lower valley of the Senegal River.

The objective of the study was to evaluate the effects of nine plant growth-promoting rhizobacteria (PgPR) alone or in combination on maize seed germination and seedling growth under laboratory and greenhouse conditions. The germination and growth tests were carried out in square petri dishes and pots. Maize seeds were inoculated with suspension of 108 CFU/ml of rhizobacteria. The experimental device was a random block of 16 treatments with four repetitions. germination test results showed that seeds inoculated with PgPR including the control induced good germination in the range of 93.75% to 100%. The vigor index and root length of the seeds treated with Bacillus panthothenicus were significantly improved by 76.64% and 58.86%, respectively, while the maximal lengths of the seedlings were obtained with Pseudomonas cichorii with an increase of 118.95%. In greenhouse experience, data demonstrated that Serratia marcescens better improved the leaf area, height and underground biomass, respectively by 58.83%, 108.43%, and 59.16% as compared to the control. The highest fresh aerial biomass and air dry matter was obtained with plants treated only with Pseudomonas putida. These results show the potential to use such rhizobacteria as biofertilizers to improve maize productivity in Benin.

Molecular Plant 2017年第6期10卷 785-787页

作者： Lucie Camut Jean-Michel daviere Patrick Achard Institut de biologie moleculaire des plantes CNRS Universite de Strasbourg 12 rue du General Zimmer 67084 Strasbourg Cedex France

Plants are sessile organisms that integrate growth responses to multiple endogenous and environmental signals. The deLLA family of transcription regulators, first identified as key repressors of gibberellin （gA） signaling, have emerged as a central node of integration, thus providing a mechanism for environmentally responsive growth regulation （Oh et al., 2014）.

Sexual selection is considered the major cause of sexual dimorphism, but recent observations suggest that natural selection may play a more important role in the evolution of sex differentiation than previously recognized. Therefore, studying the trade-offs between natural selection and sexual selection is crucial to a better understanding of the ecology underlying the evolution of sexual dimorphism. The freshwater blenny Salaria fluviatilis, a fish inhabiting lakes and rivers around the Mediterranean Sea, displays strong sexual dimorphism in size, shape, and behavior （i.e., larger body and head size for males and higher swimming requirements for females during the reproductive period）. We tested for differences in sexual dimorphism in size and shape between the populations from lake and river habitats with the goal of identifying the trade-offs between natural and sexual se- lection that underlie variations in sexual dimorphism in this species. Our results show i） differences in sexual size dimorphism （SSized） in accordance to Rensch＇s rule （i.e., larger individuals in rivers associated with higher SSized）, and ii） a decrease in shape differentiation between males and fe- males in lake populations. Together, this suggests that the different environmental conditions between lake and river habitats （e.g., resource limitations, predation pressure, water velocity） affect the relative importance of sexual selection in the display of sexual dimorphism within the species. This study highlights the importance of considering the environmental conditions to which populations are exposed to better understand the ecology underlying the evolution of sexual dimorphism.

Lima bean is a tropical and subtropical legume from the genus Phaseolus which is cultivated for its importance in food and in medicine, but which remains a Neglected and Underutilized Crop in Benin. Understanding the genetic diversity of a species’ genetic resources is useful for the establishment of appropriate conservation strategies and breeding programs and for sustainable use. We use 6 out of ten SSR markers to analyze the diversity and population structure of 28 Lima bean landraces collected in Benin. A total of 28 alleles with an average of 4.16 alleles per SSR were amplified. The Polymorphic Information Content value ranged from 0.079 to 0.680 with an average of 0.408. The analysis of population structure revealed three subpopulations. PCoA revealed three well-separated clusters among the analyzed accessions in accordance with the population structure results and the clustering based on the Neighbor-Joining tree. amOvA showed highly significant (p = 0.001) diversity among and within populations. Hence, 32% of the genetic variation was distributed among the population and 68% was distributed within populations. A high PhiP value (0.321) was found between the three sub-subpopulations indicating a high genetic differentiation between these sub-subpopulations. By exhibiting the highest average number of alleles, Shannon-Weaver information and Shannon-Weaver diversity indices, and the highest mean number of private alleles, subpopulation 1 is the main gene pool of the analyzed collection. The present study is an important starting point for the establishment of appropriate conservation strategies and breeding programs for Lima bean genetic resources.

In previous study, we demonstrated that the specific activity of d-glyceraldehyde-3-phosphate dehydrogenase (gAPdH, EC 1.***.1.12) in skeletal muscle of induced hibernating jerboa (hibernating gAPdH) was 3-4 folds lower than that of the one in the skeletal muscle of the euthermic jerboa (euthermic gAPdH). A significant decrease in both gAPdH protein and gapC mRNA levels occurs when hibernating, but the purified hibernating gAPdH is less active than the euthermic gAPdH. To investigate the physico-chemical basis of this lower activity, the behaviour during thermal inactivation of skeletal muscle gAPdH from hibernating and euthermic tissues was examined by a variety of spectroscopic techniques, including fluorescence emission, circular dichroism and ultraviolet absorption. A clear resistance to thermal denaturation was observed in the hibernating gAPdH compared with the euthermic gAPdH. The different temperature of denaturation found in these proteins by both fluorimetry and circular dichroism indicates that there might exist conformational changes of gAPdH upon hibernation that could affect the stability of this enzyme.

despite the areas restriction reserved for pearl millet cultivation in Hoggar region, there is an important diversity, which has occupied an essential place in the inhabitants’ diet. For a better knowledge of its biodiversity, seven sites were prospected during the plant maturation period. The morphological and cytological study was undertaken on the basis of the descriptors parameters of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). The most widely varied variables were the Height of the Plant (HP), Stem diameter (ST), Panicle size;Length (PL), Width (PW) and Color (PC). While very low variation was noted in 3rd leave dimensions;Leaf Length (LL), Leaf Width (LW), Number of Nodes (NN) and Seed Form (SF). Therefore, local millet (***, MLH.Z1) and some domesticated (MdH. Saf, MdH.S) appeared as the best groups, based on their panicle characters and seed nutritional quality. Agro-morphological changes detected in this study, show that the majority of millet domesticated (MdH. Saf. P, MdH. Sepl) are generally, classified in second place and used as fodder in the Hoggar region.
