Salinity stress is an important challenge for wheat production in the world. Plant growth promoting rhizosphere bacteria, isolated from halophytic plants, can increase the tolerance of crop plants to salinity by direct and indirect mechanisms. In this study, plant growth-promoting traits of bacterial strains (Bacillus safensis, Bacillus pumilus and Zhihengliuella halotolerans), isolated from the rhizosphere of several halophyte plants, were deterimined and their effects on some vegetative traits and ionic content of wheat plant irrigated with saline water ( 0.2, as control,  4, 8 and 16 dS/m) were measured. Result showed that all three bacteria were able to produce auxin, hydrogen cyanide, siderophore, 1-aminocyclopropane-1-carboxylic acid deaminase and soluble phosphate. The increase in salinity levels caused increase in the concentration of sodium and decrease in the concentration of potassium, calcium and phosphorus in wheat leaves, as well as decrease in stem length, shoot and root dry weight, root to shoot dry weight ratio and total biomass. In wheat plants irrigated with saline water and inoculated with the bacterial strains, sodium concentration decreased up to 17.7% and concentrations of potassium, calcium, phosphorus and potassium to sodium ratio increased up to 33, 25.7, 200.4 and 41%, respectively. The most efficient bacterium was found to be Z. halotolerans. All bacterial isolates also increased stem length, shoot and root dry weight, root to shoot dry weight ratio and total biomass by 17, 58.6, 137, 88 and 66 %, respectively. The results of this study showed that the plant growth-promoting bacteria of rangeland halophytic plants potentionally improve the growth indices of wheat plants in saline conditions. These results also showed that the rhizosphere of halophytic plants in rangelands can be a good source for the isolation of salinity-resistant bacteria to improve the resistance of wheat plants to salinity.

The faunistic investigation of beetles has been of a great importance in Iran due to the impresive diversity of species, which is highly promoted by the climatic variation of the Country. Therefore, detection of the ingenious regions, such as Taleqan, is important. In this study, mite-related beetles which were sampled from different areas of Taleqan were investigated and 14 species belonging to 13 genera and 9 families, including Buprestidae, Carabidae, Cerambycidae, Cicindellidae, Lucanidae, Malachidae, Meloidae, Scarabaeidae and Tenebrionidae, were identified. In addition, mite specimens were found to be from different groups, including Mesostigmata, Heterostigmata, Trombidiformes and Sarcoptiformes. New records of mites and their corresponding hosts in Iran were as follows: Alliphis kargi on Scarabaeus pius and S. typhon (Scarabaeidae), Antennoseius sp. on Pterostichus sp. (Carabidae), Parasitengona species on Julodis andreae (Buprestidae) and Mylabris syrica (Meloidae), Prostigmata species on Aegosoma sabricorne and Cerambyx dux (Cerambycidae), Hypoaspis maryame on Pentodon idiota and Oryctes sp. (Scarabaeidae), and H. phyllognathi on Dorcus parallelipipedus (Lucanidae).

Arceuthobium oxycedri is commonly known as dwarf mistletoe and grows on and infects cypress species. The semi-parasitic plant was observed in three locations of Juniper Reza Abad in Semnan Province, Chahar Bagh Area of Gorgan and Zanjan Province. In this study, the anatomical and micromorphological characteristics of the species were evaluated to facilitate the identification of this semi-parasitic species in Golestan province. The outcomes of the analysis indicated that the estimation of infestation rate in dwarf shrub trees is unattainable through factors such as canopy percentage, stand gender, slope percentage, and slope orientation. Examination of the stem's transverse section revealed that, across all three elevations, there were no variations in brain size between the semicircular cross-section and the sink's thickness. Analysis of pollen demonstrated that every pollen grain is classified as Monad, exhibiting three to five deep and asymmetric grooves of varying sizes (tricolpate). In regards to their morphology, they exhibit an oblatespheroidal shape adorned with sharp exine decorations. Overall, given the novelty of this study on dwarf mistletoe species, the discoveries hold significant systematic implications for the identification of analogous species documented in alternative juniper habitats within Iran.

In this article, a new record of Astragalus suffalcatus Bunge, from section Dissitiflori Bunge of the genus Astragalus, is presented. This species occurs in northeastern Iran, in North Khorasan Province, and has previously been reported from Afghanistan and southwestern Pakistan. A herbarium specimen image, distribution map, conservation status map, and a description of the species are provided.

Introduction:Hypertrophic cardiomyopathy(HCM)is a common inherited disease that can lead to acute cardiac complications.Since uric acid level is recognized as a long-term predictor for some cardiac diseases,this study aimed to compare serum uric acid levels and other risk factors between patients with HCM and healthy individuals.
Methods:This cross-sectional study was conducted on100individuals referred to a cardiology clinic.Participants were divided into two groups of50:those diagnosed with hypertrophic cardiomyopathy and non-affected individuals,who were followed for one year.Patients were compared based on age, history of alcohol consumption,myocardial infarction,and measured uric acid levels.
Results:The study found that variables such as age(P<0.001), body mass index(BMI)(P=0.017), history of alcohol consumption(P=0.006),repeat percutaneous coronary intervention (PCI)(P=0.022),myocardial infarction(P=0.041),and cardiac-related death(P=0.003)were significantly associated with HCM patients compared to the control group. Overall, major adverse cardiac events(MACE)were also significantly linked to the case group(P<0.001).However,no significant association was found between uric acid levels and any of the variables.In the long-term analysis,smoking was the only factor that increased the risk of cardiovascular events by nearly27-fold.
Conclusion:The results indicated that age, history of alcohol consumption, and prior myocardial infarction are risk factors associated with HCM.Uric acid levels did not prove to be a predictor of cardiovascular events within one year in patients with hypertrophic cardiomyopathy.
