Abstract
Secondary metabolites, such as phenolic compounds, play an important role in alleviating salinity-induced negative effects in plants. The present study focused on seed priming and foliar application of a potent phenolic compound, coumarin, to induce salinity tolerance in Sorghum bicolor var. SS-77. Based on pilot experiment, 100 mg L-1 concentration of coumarin was applied to mitigate the negative effects of salinity on Sorghum, grown at 0, 100, and 200 mM NaCl under netted greenhouse conditions. Coumarin was applied to each salinity treatment in four different ways (i) non-primed control (NP), (ii) seed priming (COP), (iii) foliar application (COF), and (iv) a combination of seed priming and foliar application (COPF). Salinity stress significantly reduced the plant growth, biochemical attributes, and photosynthetic efficiency of Sorghum, whereas coumarin treatments (COP, COF, and COPF) showed a significant increase (P< 0.01) in above-mentioned parameters at all salinities. Among all, the combined treatment (COPF) showed maximum increase in growth, biochemicals, photosynthetic pigments, antioxidant enzymes, and photosynthetic efficiency parameters. Therefore, it is suggested that a combination of seed priming and foliar spray of 10 mg L-1 coumarin is more suitable than their individual applications. It is an environment friendly and economically feasible approach that will be used to improve salinity tolerance of Sorghum and helpful to get considerable biomass from saline degraded lands to fulfill food, fodder, and energy demands of the ever-growing population.

Abstract
Introduction. Sorghum is available cereal seeds of African origin belonging to the Poaceae family. However, its metabolites and proximate composition have not studied well, which led to the under-utilization of this cereal. This research aimed to investigate the classes of phytochemical and proximate compositions of sorghum extract in order to assess its nutraceutical potential for food chemistry and dietary formulations.
Study objects and methods. We studied the sorghum seed oil extract obtained with the help of a Soxhlet extractor. Sorghum was purchased in Ota, Nigeria. The bioactive compounds were identified by standard methods of phytochemical screening, the nutritional content was investigated with proximate analysis, and the secondary metabolites in the sorghum extract were determined using gas chromatography – mass spectrometry (GC-MS).
Result and discussion. The phytochemical screening showed the presence of steroids, saponins, terpenoids, alkaloids, cardiac glycosides, and quinones in the sorghum extract. The oil yield obtained was 11.00 ± 0.18%. The proximate analysis revealed 5.94% moisture content, 3.05% ash, 0.20% crude fiber, 11.00% fat, 5.54% protein, and 74.27% carbohydrates. The selected physicochemical parameters measured in the sorghum extract included cloud point (0.40°C), specific gravity at 25°C (0.81), and refractive index (1.46). The GC-MS analysis revealed the presence of 9,12-octadecadienoic acid (Z,Z)-, stigmasterol, 8-dodecen-1-ol, acetate, (Z)-, vitamin E, linoleic acid ethyl ester, and 9,12-octadecadienoic acid, methyl ester, which accounted for about 85% in the sorghum composition. Other constituents, presented at lower amounts, included 12-heptadecyn-1-ol, 1H-Imidazole-5-ethanamine, 1-methyl-, and cyclononene.
Conclusion. The findings of this study revealed high nutritive potential of sorghum, which make it a rich source of energy for humans and animals.

Abstract
Major problems associated with the study of mushrooms in Nigeria are inaccuracy in identification, low bio-efficiency of commonly used substrate and difficulty in composting of substrates. The current study attempts the identification and characterization of Pleurotus species commonly cultivated in Western region of Nigeria, and evaluates the effectiveness of agricultural wastes in mushrooms cultivation. Molecular characterization was carried out for species identification. Different substrates combinations at ratio 1:1 were used. Molecular characterization revealed that the Pleurotus species grown in most farms and research institutes in South-western Nigeria are predominantly P. ostreatus and P. pulminarius. Palm bunch + Rice bran (8.24 ± 0.16) ramified almost twice faster than sawdust alone (4.98 ± 0.31) or any of the other substrates containing it. Fermented bunch (7.36 ± 0.19), the only substrate not sterilized also ramified faster than sawdust alone. All the other substrates compounded with palm bunch and shaft ramified faster than sawdust as lone substrate. In terms of yield, Palm bunch + Rice bran gave the highest (1774.75 g), followed by shaft + rice bran (1483.70 g), while the least value of 326. 94 g was obtained from sawdust. The highest value of biological efficient (BE) (100.57 g) and productivity (PT) (17.46 g) were obtained from shaft + Wheat bran and Palm bunch + Rice bran respectively, while sawdust gave lowest values of 13.08% and 3.23% for BE and PT respectively. Results obtained have shown that bunch and shaft supplemented with wheat and rice bran gave better yields and can be recommended for commercial mushrooms cultivation.

Abstract
Understanding the dynamics of food production is critical to improving food security. This is particularly important in regions that rely on subsistence agriculture with little adaptive capacity to climate change. Sorghum plays an important role in food security in some of the poorest parts of the world. This article reviews the literature to identify and examine the major factors affecting sorghum production in three major production regions. Factors were not categorized ex ante but rather determined from the review. Ten major factors were identified as having notable impacts on sorghum production: climate change, population growth/economic development, non-food demand, agricultural inputs, demand for other crops, agricultural resources scarcity, biodiversity, cultural influence, price and armed conflict. This synthesis revealed that (1) multiple factors simultaneously affect sorghum production; (2) the effect of each factor is greatly influenced by the magnitude and certainty of one or more other factors; and, (3) factors differ in relevance and degree with regard to geography. Generally, improved agricultural inputs, population growth/economic development and climate change have substantial influence on sorghum production. However, local dynamics likely go beyond these broad trends and more exhaustive, locally-focused studies are needed for actionable planning purposes.

Abstract
Despite its economic, social, biological, and cultural importance, wild forms of the genus Phaseolus are not well represented in germplasm banks, and they are at great risk due to changes in land use as well as climate change. To improve our understanding of the potential geographical distribution of wild beans (Phaseolus spp.) from Mexico and support in situ and ex situ conservation programs, we determined the climatic adaptation ranges of 29 species and two subspecies of Phaseolus collected throughout Mexico. Based on five biotic and 117 abiotic variables obtained from different databases-WorldClim, Global-Aridity, and Global-PET-we performed principal component and cluster analyses. Germplasm was distributed among 12 climatic types from a possible 28. The general climatic ranges were as follows: 8-3,083 m above sea level; 12.07-26.96°C annual mean temperature; 10.33-202.68 mm annual precipitation; 9.33-16.56 W/m2 of net radiation; 11.68-14.23 hr photoperiod; 0.06-1.57 aridity index; and 10-1,728 mm/month of annual potential evapotranspiration. Most descriptive variables (25) clustered species into two groups: One included germplasm from semihot climates, and the other included germplasm from temperate climates. Species clustering showed 45% to 54% coincidence with species previously grouped using molecular data. The species P. filiformis, P. purpusii, and P. maculatus were found at low-humidity locations; these species could be used to improve our understanding of the extreme aridity adaptation mechanisms used by wild beans to avoid or tolerate climate change as well as to introgress favorable alleles into new cultivars adapted to hot, dry environments.

Abstract
Sulfur is an essential element for all living organisms. Plants can convert inorganic sulfur into organic sulfur compounds by complex enzymatic steps. In this study, we conducted a genome-wide analysis of sulfate transporter genes (SULTRs) in the sorghum (Sorghum bicolor) genome and examined expression profiles of SbSULTR genes under 200 µM cadmium (Cd) exposure. As a result of sorghum genome analysis, 11 SULTR genes were identified, including SbSULTR1;1, SbSULTR1;2, SbSULTR1;3, SbSULTR2;1, SbSULTR2;2, SbSULTR3;1, SbSULTR3;2, SbSULTR3;3, SbSULTR3;4, SbSULTR3;5, and SbSULTR4. Given names are based on phylogeny and chromosomal locations. Except SbSULTR4, all SbSULTR proteins contained Sulfate_transp (PF00916), STAS (PF01740) domains and 12 trans-membrane domains. Phylogenetic analysis revealed that four major groups were identified such as SULTR1, 2, 3, and 4 groups and SULTR4 group was separated to other SULTR groups. In promotor sequences of SbSULTR genes, many diverse cis-acting elements were found mainly related with physiological processes such as light, stress and hormone responsiveness. The expression profiles of SbSULTR genes showed that SULTR1;2, 1;3, 3;3, and 3;5 genes up-regulated in root, while expression level of SULTR4 decreased under 200 µM Cd exposure. The predicted 3D structures of SULTR proteins showed some conformational changes, suggesting functional diversities of SbSULTRs. Finally, results of this study may contribute towards understanding SbSULTR genes and their regulations and roles in Cd stress in sorghum.

Abstract
Inter simple sequence repeats (ISSR) analysis was used to determine the genetic diversity among 15 genotypes of sorghum [Sorghum bicolor (L.) Moench] growing in some parts of Saudi Arabia and Yemen. A total of 92 alleles were amplified, with an average of 13 ISSR alleles per primer. Cluster analysis divided the 15 genotypes into two main groups. Group A consisted of five genotypes with white grains from Jazan and Abha with a similarity coefficient range of 0.527 to 0.818. Group B was comprised of 10 genotypes; two genotypes from Al-Qassim were clearly delimited from the remaining eight samples with a coefficient range from 0.709 to 0.490. The eight genotypes were divided into two clusters; one was comprised of landraces with dark grains from Abha in Saudi Arabia and Ab in Yemen, with a similarity coefficient range between 0.563 and 0.781, and the other cluster was differentiated into three white-colored-grain genotypes and one colored-grain genotype; all samples from North Yemen had a similarity coefficient range from 0.454 to 0.800. The current results encourage further collection and authentication of sorghum landraces in the gene banks of Saudi Arabia.
