“…Moreover, they showed that Reseda extract was an interesting raw material dyeing purposes and for further pharmacologic investigation. In another study, Berrehal et al 38 investigated the methanolic and n-butanolic extracts of R. duriaeana and R. villosa for their antioxidant activity. The authors indicated that the methanolic and n-butanolic extracts of R. duriaeana exhibited better antioxidant activity than the respective extracts of R. villosa.…”

ÖZAmaç: Bu çalışmada Diplotaxis tenuifolia ve Reseda lutea'nın çiçek ve yapraklarından elde edilmiş olan metanol özütlerinin AR, CAT, GST ve GPx enzimlerinin aktiviteleri üzerinde olan etkilerinin araştırılması amaçlanmıştır. Gereç ve Yöntemler: Bu çalışmada, bitki örneklerinin toplam fenolik ve flavonoid içeriği; Folin-Ciocalteu ve alüminyum klorür reaktiflerinin yardımıyla kolorimetrik yöntemlerle değerlendirilmiştir. Ayrıca özütlerin CAT, GST, GPx ve AR enzimlerinin aktiviteleri üzerindeki etkileri kinetik analizler ile araştırılmıştır. Bulgular: En yüksek miktarda fenolik ve flavanoid içeriği sırasıyla 144.49±0.29 mg gallik asit eş değeri/L ve 250.485±0.002 quercetin eş değeri/L tespit edilmiştir. GST ve GPx için en iyi aktivite profilleri sırasıyla 121±0.05 ve 140±0.001 ng/mL IC 50 değerleri ile D. tenuifolia yaprak özütünde gözlemlenmiştir. Elde edilen sonuçlara göre, R. lutea ve D. tenuifolia'nın yapraklarından elde edilen metanol özütleri, AR enzimi üzerinde önemli ölçüde bir aktivite potansiyeli göstermemiştir. Bununla beraber, çalışılmış olan çiçek ve yaprak özütlerinin hiçbiri yeterli düzeyde CAT aktivasyonu gösterememiştir. Sonuç: Çalışma sonucunda, D. tenuifolia'nın yapraklarının antioksidan enzimatik savunma sistemi üzerinde iyi bir etkiye sahip olduğu gösterilmiştir. Bu sebeple günlük diyet için iyi bir besin kaynağı olarak kabul edilebilir.

Materials and Methods: Total phenolic and flavonoid contents of the plant samples were evaluated using Folin-Ciocalteu reagent and aluminum chloride colorimetric methods. Also, the effects of extracts on CAT, GST, GPx, and AR enzyme activities were investigated using kinetic assays. Results: The highest phenolic and flavonoid contents were detected in the methanol extract of D. tenuifolia leaves with 144.49±0.29 mg gallic acid equivalent/L and 250.485±0.002 quercetin equivalent/L, respectively. The best activity profile for GST and GPx were observed in the extract of leaves belonging to D. tenuifolia with IC 50 values of 121±0.05 and 140±0.001 ng/mL, respectively. According to the results, methanol extracts from leaves of R. lutea and D. tenuifolia showed no significant activity potential on AR. Moreover, none of the studied extracts demonstrated any reasonable CAT activation potential. Conclusion:The results indicated that leaves of D. tenuifolia had good effect on the antioxidant enzymatic defense system, which it makes it a good constituent of the daily diet.

“…In this context, different economically relevant autochthonous plants in Algeria ( Table S1 ) [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ], were chosen in their natural area in order to characterize their associated bacterial communities. In addition, the composition of the bacterial communities was also related to climatic variables and to the chemical and physical parameters of the soils.…”

Algeria is the largest country in Africa characterized by semi-arid and arid sites, located in the North, and hypersaline zones in the center and South of the country. Several autochthonous plants are well known as medicinal plants, having in common tolerance to aridity, drought and salinity. In their natural environment, they live with a great amount of microbial species that altogether are indicated as plant microbiota, while the plants are now viewed as a “holobiont”. In this work, the microbiota of the soil associated to the roots of fourteen economically relevant autochthonous plants from Algeria have been characterized by an innovative metagenomic approach with a dual purpose: (i) to deepen the knowledge of the arid and semi-arid environment and (ii) to characterize the composition of bacterial communities associated with indigenous plants with a strong economic/commercial interest, in order to make possible the improvement of their cultivation. The results presented in this work highlighted specific signatures which are mainly determined by climatic zone and soil properties more than by the plant species.

“…Several of its species flourish on soils under arid environments, while others are ruderal weeds and only a few are available in high mountains [ 19 ]. Pharmacological studies of various Reseda species showed antimicrobial [ 20 ], anti-inflammatory [ 21 ], and antioxidant [ 22 ] activities. In Saudi Arabia, seven species of the genus Reseda were recorded, viz.…”

Genome size is one of the fundamental cytogenetic features of a species, which is critical for the design and initiation of any genome sequencing projects and can provide essential insights in studying taxonomy, cytogenetics, phylogenesis, and evolutionary studies. However, this key cytogenetic information is almost lacking in the endemic species Reseda pentagyna and the locally rare species Reseda lutea in Saudi Arabia. Therefore, genome size was analyzed by propidium iodide PI flow cytometry and compared to k-mer analysis methods. The standard method for genome size measures (flow cytometry) estimated the genome size of R. lutea and R. pentagyna with nuclei isolation MB01 buffer were found to be 1.91 ± 0.02 and 2.09 ± 0.03 pg/2 °C, respectively, which corresponded approximately to a haploid genome size of 934 and 1.022 Mbp, respectively. For validation, K-mer analysis was performed on both species’ Illumina paired-end sequencing data from both species. Five k-mer analysis approaches were examined for biocomputational estimation of genome size: A general formula and four well-known programs (CovEST, Kmergenie, FindGSE, and GenomeScope). The parameter preferences had a significant impact on GenomeScope and Kmergenie estimates. While the general formula estimations did not differ considerably, with an average genome size of 867.7 and 896. Mbp. The differences across flow cytometry and biocomputational predictions may be due to the high repeat content, particularly long repetitive regions in both genomes, 71% and 57%, which interfered with k-mer analysis. GenomeScope allowed quantification of high heterozygosity levels (1.04 and 1.37%) of R. lutea and R. pentagyna genomes, respectively. Based on our observations, R. lutea may have a tetraploid genome or higher. Our results revealed fundamental cytogenetic information for R. lutea and R. pentagyna, which should be used in future taxonomic studies and whole-genome sequencing.
