Read More Abstract:Bacterial endophytes are host-beneficial microbial symbionts inhabiting different plant tissues without causing damage to the host plant. To our knowledge, no previous data was available regarding the endophytic bacterial population colonizing root nodules of plant legumes in this region. Therefore, this study was conducted to identify and assess the biodiversity of the bacterial endophytes of four different legumes species of the Fabaceae family, including Chickpea, Faba bean, Common bean, and Lentil in Duhok province, using 16S rDNA sequencing. The results revealed that 69 different pure culture colonies were isolated based on the phenotypic characteristics of endophytes on YEM medium and Gram staining. Based on 16S rDNA sequencing, seventeen bacterial species have been identified, with the sequence identities ranging from 98.41-100%. They belonged to nine different bacterial genera. The identified bacterial genera were Pantoea sp. (35%), Enterobacter sp. (26%), Clostridium sp. (15%), Kosakonia sp. (9%), Pseudomonas sp. (4%), Curtobacterium sp. (4%), Erwinia sp. (3%), Salmonella sp. (3%), and Rahnella sp. (1%). These bacterial genera belonged to four Phyla, including Pseudomonadota, Bacillota, Proteobacteria, and Actinobacteria. The antibacterial sensitivity against six various antibiotics by disc diffusion method showed different resistant patterns (bacitracin 78%, amoxicillin 56%, rifampin 34%, erythromycin 11%, chloramphenicol and tetracycline 6%), respectively. The phylogenetic analysis clustered the identified bacterial endophytes into three major clades and 11 different sub-clusters (C1 to C11), with a high degree of similarity amongst bacteria belonging to the same species. In conclusion, the population densities, species richness, and frequency of isolated endophytes showed variations based on geographical locations and the type of plant legumes. Finally, the results of the current investigation might add significant knowledge regarding endophytic bacterial populations colonizing different plant legumes in this region.

Read More Hypericum (H.) triquetrifolium contains numerous bioactive molecules in the aerial parts. Such molecules have numerous biological activities, including antioxidant, anti-inflammatory, antidepressant, antimicrobial, antifungal, antiviral, and anticonvulsant compounds. Despite the presence of H. triquetrifolium in Iraq, no previous studies have examined the biochemical contents of plant in the region. This study is carried out to evaluate the variability of the essential oil profile of aerial parts of Hypericum triquetrifolium Turra. Samples were also analyzed using gas chromatography-mass spectrometry (GC-MS) with two different extraction methods, namely in-tube extraction (ITEX) dynamic headspace and hydrodistillation (HD). A total of thirty-three, forty-three, and thirty-nine compounds were identified in stem, leaves, and flowers, respectively. Monoterpene hydrocarbons were the main compounds in the essential oil extracted from different parts. The highest constituent detected in the ITEX/GC-MS in stem parts was alpha-pinene (20.47%). On the other hand, the predominated compound of the essential oil detected by the HD method was cubenol (26.72%). The essential oil extracted from leaves by ITEX and HD methods showed 43 compounds. ITEX/GC-MS detected 32 products in the essential oil of leaves; vubenol was the highest (23.64%), and Using ITEX and HD/GC–MS, a subset of 39 chemical components in H. triquetrifolium essential oil were detected in the flower. Twenty-five out of 39 compounds, were analyzed by ITEX/GC-MS. The main constituent was 3-methyl-nonane (27.76%). HD/GC-MS method was characterized by detecting 23 components in flower oil. The major chemical structure identified in the essential oil in flower by HD/GC-MS was the monoterpene hydrocarbon represented by alpha-pinene (18.39%). Our data indicates that the ITEX method is more accurate than HD in the separation of essential oil components in this plant.
