“…Closely related taxa in the genus can be compared using transverse sections of stem, petiole, peduncle and leaflets (Özgişi et al 2013, Al‐Sammarai and AL‐Khesraji 2016). Pollen morphology is also an important tool used in resolving the taxonomic problems associated with Astragalus (Erkul et al 2022). Pollen morphology in Astragalus is usually used for the differentiation of similar species and has phylogenetic significance (Pinar et al 2009).…”

“…Photographs were taken from prepared slides using a digital camera (HDCE‐50B) connected to a light microscope. For scanning electron microscopy, pollen grains were extracted from anthers and prepared following Erkul et al (2022). Pollen ultrastructure was examined and microphotographs were taken through a scanning electron microscope (Model JEOL‐5910) installed in Centralized Resource Laboratory (CRL), University of Peshawar.…”

A new species, Astragalus roseocephalus sp. nov., is described and illustrated. It is known from Islamabad Capital Territory (Margalla hills), Rawalpindi district, Hazara and Kashmir. It belongs to Astragalus section Poliothrix Bunge. Morphologically, it is closely related to Astragalus leucocephalus Benth., but differs in height, presence of connate stipules, opposed to free lateral stipules in A. leucocephalus, stipule shape, leaf length, leaflet size, number, arrangement and shape, peduncle length, corolla colour, size and shape of standard, fruit shape and number of seeds. In addition, anatomy, pollen morphology, distribution and conservation status of the new species are discussed.

“…Aside from the utility of the previously mentioned markers, a new form of marker known as CDDP has emerged as a valuable tool for measuring diversity in various plant species [18][19][20]. There have been considerable efforts in Turkey [21][22][23] and Iran [16,24] regarding the morphological diversity hub for Astragalus species.…”

Astragalus L. is one of the main genera of blossoming plants, and its diversity of species and forms is well known. The Astragalus L. taxa make a significant contribution to the mountainous and steppe ecosystems of the Kurdistan region of Iraq. Although the species within this genus have been the subject of several molecular studies, the evolutionary relationships among these species remain unidentified. Despite extensive research, little is known about the phylogenetic relationships among the various subgenera of Astragalus. This research is intended to investigate the molecular variation of 33 species of the genus Astragalus L. found in the Kurdistan area of Iraq. For molecular validations, three separate techniques (nuclear ribosomal DNA (rDNA), inter simple sequence repeats (ISSR), and conserved DNA-derived polymorphism (CDDP)) were used. With respect to Astragalus L. indentations, universal ITS1 and ITS4 gene sequencing was used, and the discovered sequences were subjected to BLAST searches in the NCBI database. A phylogenetic tree was generated with two main clades. Regarding detecting genetic diversity between the taxa, 24 molecular markers (14 ISSR and 10 CDDP) were used. High values of polymorphic materials and gene diversity were detected. ISSR markers had an average of 22.71 polymorphic bands per primer, while CDDP markers had the highest mean values for polymorphic information content (0.37), Shannon’s information index (0.27), expected heterozygosity (0.19), and unbiased expected heterozygosity (0.23). Cluster and principal coordinate analyses divided the Astragalus L. taxa into four main groups using the two molecular data sets. According to the results of the molecular variance analysis, the highest variation was detected within sections, with values of 92.01 and 89.48% for ISSR and CDDP markers, respectively. These outcomes suggest the effectiveness of molecular markers and the ITS region in determining and identifying genetic correlations between Astragalus species.

This study provides the first comprehensive report on the chemical constituents and biological activities of an important medicinal plant, Astragalus brachystachys DC. The aerial part samples were collected from Adana, Türkiye, and an ethanol extract was prepared with these parts. The secondary metabolites of the extract were determined by an LC‐HRMS analysis. The LC‐HRMS analysis showed the presence of 39 different constituents, hyperoside (303.419±10.50 μg/g extract), p‐coumaric acid (256.975±8.51 μg/g extract), and rutin (72.684±2.23 μg/g extract) were determined as major compounds in the aerial parts ethanol extract. Attributed to its high total phenolic (58.53±1.30 μg PEs/mg extract) and total flavonoid content (29.98±0.83 μg QEs/mg extract), the extract demonstrated strong antioxidant activity according to three different assays namely DPPH free (IC50: 33.08±0.61 mg/mL), and ABTS cation radical scavenging (IC50: 15.39±0.72 mg/mL) and CUPRAC activity (A0.5: 36.25±0.28 mg/mL) methods. In vitro assays showed that cholinesterase inhibitory activity results were found to be exceptional with 85.95±0.52 % inhibition on acetylcholinesterase and 66.32±1.33 % inhibition on butyrylcholinesterase at 200 mg/mL. Regarding antimicrobial properties, Astragalus brachystachys DC extract was found to be effective against Enterococcus faecalis with a MIC value of 39.06 μg/mL.
