So, the current study aims at revealing distinguishing characters, and assessing the taxonomic relationships between studied taxa using recently proposed genera versus Acacia s.l. genus in conventional classificatory systems. Macro-, micro-morphological characters, and SDS-protein pattern of 13 Acacia s.l. spp. were investigated focusing on seeds using the scanning electron microscope (SEM). The generated UPGMA-cluster based on 106 morphological and biochemical character-states split the studied Acacia s.l. taxa into two groups; (1) comprised genera of Vachellia, Acacia s.s. and Faidherbia, and (II) Senegalia genus. The present results gave accurate discrimination of genus Acacia s.l., confirmed the need of its retypification in the Middle East according to the new system of classification and show the close relation between Vachellia, each of Acacia s.s. and Faidherbia genera.","PeriodicalId":22404,"journal":{"name":"THE EGYPTIAN JOURNAL OF EXPERIMENTAL BIOLOGY (Botany)","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87240864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the high antibiotic resistance of P. aeruginosa and the lack of other effective therapeutic agents, treating diseases caused by this bacterium could be challenging. Therefore, finding novel solutions to control and prevent highly resistant strains of P. aeruginosa is paramount. After isolation and identification of Lactobacilli with known probiotic properties such as L. acidophilus, L. paracasei, L. rhamnosus, and L. bulgaricus using PCR technique, and preparation of their corresponding phage (PAO1 Φ), probiotics and phage were used individually and in combination to treat burn infection caused by P. aeruginosa in a mouse model. The results revealed that the combination of phage with probiotics can be highly effective for treating P. aeruginosa burn infections. Our study showed that the most effective multiple cocktails of Lactobacilli for the treatment of P. aeruginosa infection, were L. rhamnosus + L. bulgaricus + L. paracasei cocktail in mixture with phage (PAO1 Φ). The study proposes an alternative method for the treatment of P. aeruginosa infections. The combination of probiotics with phage could be proposed as a new therapeutic agent for treating P. aeruginosa infections.","PeriodicalId":22404,"journal":{"name":"THE EGYPTIAN JOURNAL OF EXPERIMENTAL BIOLOGY (Botany)","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88149041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In North Sinai, these environments have not gotten much attention. However, the focus of our investigation was on the salterns' waters and saline soil. The study of this microflora showed that it had a lot of different shapes, functions, and ways of using energy. The molecular analysis provided us with a phylogenetic relationship that included Aspergillus isolates as well as archaeal isolates from the genera Haloarcula, Haloferex, and Halobacterium, and also bacteria related to Halomonas and Brevibacillus. The majority of isolates expressed hydrolytic enzymes at high salt concentrations. Finally, the North Sinai Solar Saltern is rich in halophilic populations that produce industrial hydrolytic enzymes.","PeriodicalId":22404,"journal":{"name":"THE EGYPTIAN JOURNAL OF EXPERIMENTAL BIOLOGY (Botany)","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75855148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DNA banking can be considered a complementary method for preserving plant species by preserving genomic DNA at lower temperatures. This approach to maintaining biological information allows researchers to search for new genes and their products. Therefore, in this review, we describe and analyze the DNA barcoding of family Boraginaceae to conserve and further manipulate this rare and endangered plants species to enhance its yield and quality characteristics. The non-coding DNA regions (such as ITS and rbcL) are presumed to be more useful at lower taxonomic levels because of their faster evolutionary rates. The present study aims to inspect whether these plants can be categorized into different species or not, and DNA barcoding is used to clarify the dispute. The DNA barcode marker used ITS and rbcL, and sequence analysis was performed using the online tool BLAST of the NCBI database and based on maximum identity and dendrogram.","PeriodicalId":22404,"journal":{"name":"THE EGYPTIAN JOURNAL OF EXPERIMENTAL BIOLOGY (Botany)","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76636441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanoparticles have potential to improve growth and yield of wheat crop. This paper studies effects of wheat grains priming in nanoparticles and bulk calcium hydroxide on germination, growth criteria, photosynthetic pigments, carbohydrates, and proteins content of wheat. Calcium hydroxide nanoparticles were 73nm size. Wheat grains were soaked for four hours in 0, 8.0, and 16.0 mM nanoparticles and 16 mM bulk solutions of calcium hydroxide for germination experiments in the laboratory. Also soaked grains were cultivated in clay-sandy soil (2:1 w/w), in small plastic bags in the green house of faculty of science for studying growth and some metabolic activities. Results showed that application of calcium hydroxide nanoparticles increased germination percentage significantly with 8 and 16 mM nanoparticles in comparison to control and calcium hydroxide bulk. Grain germination was hundred percentages with the 16.0 mM nanoparticles concentration. Root and shoot fresh weight and dry weight increased significantly (about 30%) at 8 and 16 mM as compared to control and calcium hydroxide bulk. Higher concentration (16 mM) of calcium hydroxide nanoparticles significantly enhanced fresh weight, dry weight, chlorophyll and protein content over control and calcium hydroxide bulk. Nonetheless, effect of 8 and 16mM caused more utilization of carbohydrates in the plant growth as compared to control. Calcium hydroxide nanoparticles have definite potential to increase crop growth and yield. Nonetheless, comprehensive experimentation is required to establish the most suitable concentration, size and mode of application of calcium hydroxide nanoparticles for higher growth and yield in the field crops.","PeriodicalId":22404,"journal":{"name":"THE EGYPTIAN JOURNAL OF EXPERIMENTAL BIOLOGY (Botany)","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86476269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
