Abstract: Morphological characterization and molecular DNA techniques allowed the identification of the Aspergillus sample sent to MACROGEN SOUTH KOREA. Objective: To perform phenotypic and genotypic characterization of the genus Aspergillus by the Next-Generation Sequencing method (NGS). Methodology: The type of study is exploratory and experimental. It was carried out in two phases: first in the collection of seeds of Caesalpinia coriaria and second an initial macroscopic and microscopic characterization of the isolation of Aspergillus was carried out in 2006, a notarial act was carried out in 2007, studies of simple microscopy and scanning electron microscopy and PCR of the fungus found in Mexico 2008 and published in the journal La Universidad in 2008, then the extraction of gDNA, qPCR, cDNA was performed in 2024 at MACROGEN INC. by Metagenome Shotgun Sequencing Reports. Results: The gDNA genome was extracted obtaining a maximum concentration of 12.297 ng/ul, volume 30 ul, total amount 0.369 and DIN 6.4 maximum level 8732 sample intensity for 15000 bp, the quantum qDNA was obtained at 624 bp at a concentration of 103.24 nM and 41.87 ng/ul and cDNA. From the gDNA extraction of the TapeStation gDNA Screen, a maximum concentration of 12.297 ng/ul, volume 30 ul, total quantity 0.369 and DIN 6.4 maximum level 8732 sample intensity for 15000 bp in quality control was obtained. qPCR 624 bp were obtained at a concentration of 103.24 nM and 41.87 ng/ul with the TruSeq Nano DNA library (350_META). cDNA library 33 library kits were used. Total, of bases obtained were 11,705,895,990 bp, total, of readings were 77,522,490. GC nucleotide content % 49.7 and AT % 50.30, GC base content was 49.7% and AT was 50.3, Metric base content Q 20: 95.1 and Q 30: 88.3, Q30 cycle data quality high value. FASTQ and FASTA formats were used for encoding and full base-pair sequencing. Raw data Value. 38,761.245 N, adapter quality and trimming. (Quality and adapter trim.) was 32,535,420, Elimination of contaminants was 30,961,740. From the Krona taxonomy, Aspergillus was reported. Heatmaps specie report varieties. Conclusions: Aspergillus sp was found by the NGS sequencing method with a variety of species, in previous studies in 2006 it was named the species uessalvadorensis.

Abstract: Tomato (Lycopersicon excluentum. L) is one of the most important fruit vegetables for human consumption. However, its cultivation is confronted with the use of chemicals that are toxic, expensive and cause enormous damage to the environment. Hence the search for environmentally friendly alternatives to improve yields in poor soils. Thus, the use of mychorizian fungus, Gliricidia sepium and neem oil (Azadirachta indica) on the growth and production of tomato in this work could constitute a draft solution. On a plot of 492m2, consisting of 126 ridges in two blocks, the hybrid RAJA F1 and standard RIO POWER GRANDE tomato varieties consisting of seven treatments each were grown in the dry and rainy seasons of the year 2024 at IRAD Foumbot in Cameroon. An ANOVA of the results obtained was carried out using R.4.2.2 software and Excel 2019 and the Tukey test was used to compare the means of the treatments. At 12 weeks after transplantation in the field, the T2 and T3 treatments fertilized with mychorizian fungus respectively presented significantly greater stem heights, number of leaves and leaf areas at P < 0.05 than the other treatments. The number of terminal buds, flowers, fruits and yield per hectare was significantly higher for the T2 and T3 treatments compared to the other treatments while the T6 and T7 treatments fertilized with Gliricidia sepium had significantly higher fruit weights of 10 fruits than the other treatments. The mychorizian fungus, Gliricidia sepium and neem oil represent alternatives that can practically replace the fertilization of tomatoes with chemical fertilizers.

Abstract: Wild edible plants provide a natural food supply that can reduce hunger and malnutrition. Although wild edible plants are widely used in Ethiopia, little research has been done on their nutritional makeup. The study's goal was to assess the vitamin C content and proximate composition of four wild edible plants that were chosen from the Kebridehar district in the Khorahie zone of the Somale region of Ethiopia. Vitamin C and the proximate composition parameters (moisture, ash, crude fat, crude fiber, crude protein, carbohydrate, and energy) were determined using the methods of the Association of Official Analytical Chemists. The descriptive statistical analysis was conducted using programs like Microsoft Excel and SPSS. The study found that the average moisture, ash, crude fat, crude fiber, crude protein, carbohydrate, and total energy contents of Moringa stenopetala leaf samples were 7.2, 11.83, 20.00, 26.00, 17.50, 17.47, and 319.8 (in terms of g/100g). Commiphora rostrata leaves had the highest carbohydrate content (32.00 g/100 g), followed by Ziziphus Mauritia leaves (29.98 g/100 g), according to the nutritional analysis results. Ziziphus mauritiana, Commiphora rostrata, Cibirhiza spiculata, and Moringa stenopetala showed highly significant differences. In general, the study area revealed that multiple comparisons by post hoc test revealed a p ≤ 0.05, indicating a significant difference. The study's findings imply that eating these nutrient-dense wild edible plants may contribute a significant quantity of vitamin C and other nutrients to the human diet. The results of this study suggest that the local population needs assistance through education and awareness-raising on the sustainable management and utilization of plant resources.
