In this research, plant morphology and pollen micromorphology of 14 populations of 3 species belonging to two sections Plethiosphace and Hemisphace of Salvia genus in Iran were studied. In the morphological study 25 quantitative and qualitative characters were investigated and the results clearly separated the species into two groups. The pollen grains from the herbarium specimens were prepared by acetolysis method and then 4 quantitative characters were examined by light microscopy. Data was processed by principal component analysis method. Results indicated that although the pollen grains in the section were comparatively homogenous and all of them were 6-colpate with reticulate ornamentation, a considerable variation in the quantitative characters studied turned out to exist. However among the characters studied, equatorial and polar diameters of pollen grains were the most significant and based on these characters the members of these sections can be divided into two groups.

Trigonella L. is one of the important genera of the family Fabaceae, many species of which have nutritional and medicinal properties. In this investigation, morphological characters related to habit and pollen grain of three Trigonella species i.e., T. disperma, T. subenervis and T. aphanoneura were studied. Oils from the aerial parts of two species were investigated by GC and GC/MS methods and compared with T. disperma, which had been studied in advance. T. subenervis represented oils rich in spathulenol (15.1%). It also contained a small amount of germacrene D (0.6%). T. aphanoneura also represented oils rich in spathulenol (10.4%). The amount of four compounds in this species was ≤1%, and n-octyl acetate was the lowest component in quantity. According what we found out, phytochemical and morphological data could clarify the relationships among the Trigonellaspecies better than pollen morphological data

In this study the morphological and micromorphologcal characters of Ranunculus Sect. Batrachium species in Iran have been investigated. The characters describe leaf, petal and fruit, in addition to pollen grains in four species of the genus including, R. sphaerospermus Boiss. & Blanche, R. trichophyllum Chaix ex. Vill., R. rionii Lagger and R. peltatus Schrank. Pollen grains were tricolpate and had species-specific shapes. The sculpture of the exine was echinnate in all of the species studied. Seven morphological characters have been studied using statistical methods and SPSS software has been used in order to group the species. These analyses indicated that R. sphaerospermus was a valid species and very similar to R. peltatus. Also, intraspecific diversity in R. trichophyllum was confirmed by statistical methods

In order to investigate the differences in the shape of the big-head and two morphotypes of Phytophagous fish by geometric morphometric technique, 30 samples of each group, with a mean standard length of 25 ± 3 cm, were prepared. After fish were anesthetized by 1% Clove powder extract and stabilized in formalin buffer 4%, 6-megapixel digital images of the left profile of the specimens were prepared. A total of 17 morphological landmarks were digitized by tpsDig2 software and the tps files were prepared. All non-shaped data were removed from landmark coordinates by generalized procrustes analysis. After the approval of regression between shape space and tangent space, data were analyzed using Principal Component (PCA), Canonical Variation (CVA) and Cluster Analyzes (CA) methods in PAST and TPS series. According to the results, the head length and height, the size of dorsal fin, the length of pre ventral distance, the height of caudal peduncle and the degree of posterior position of the pectoral fin in bighead carp, are some of the distinctive morphological features among species, mainly related to their ecological niche (specially feeding strategies). In the case of silver carp variants, the posterior position of pectoral fin base in silver carp-R that is close to bighead carp, may be due to hybridization between bighead carp and silver carps.

Pterocephalus (Caprifoliaceae) consists of 30 species worldwide, mainly distributed in the temperate regions of the northern hemisphere, of which 14 species were reported from Iran, including five endemic ones. In this study, 35 leaf-related traits and 30 peduncle-related traits were investigated by light microscopy of 15 samples from 11 Iranian species of Ptreocephalus. Our results showed that there were two types of midrib, six types of leaf indumentum and five types of peduncle indumentum. Crystalized calcium oxalate was observed in the leaves and peduncles of most species except in P. plumosus and P. brevis. The profiles of the peduncles were hexagonal, circular or elliptical. The vascular cylinder shape varied from circular to sinuate form. P. wendelboi, with a very different morphology as compared with other species, also exhibited different anatomical characters. The hexagonal sections of peduncle in P. ghahremanii and P. kurdicus and two samples of P. szovitsii were found to be very similar. However, the mentioned characters were found to be less informative or charachterisation of other species. In conclusion, the results showed that the anatomical characters of the leaves and peduncles might have some taxonomic importance in the identification of some species of the genus Pterocephalus.

Sexual dimorphism in the ratio of digits length is a morphological feature resulted from the interaction between sex hormones and prenatal Hox genes, the latter is known to control the development of both limbs and genitals. The status of this trend and ratios have been investigated in various animal groups, including humans, other mammals, birds, reptiles, and amphibians. In this study, the body length and sexual dimorphism in the second-to-fourth, second-to-third and third-to-fourth digit lengths ratios (i.e., 2D:3D, 2D:4D, 3D:4D) of left fore and hind limbs were investigated in 54 specimens of toads collected from the northern Iran, including Bufo viridis (16 males and 19 females) and Pelobates syriacus (10 males and 9 females). In addition, the body length of the studied specimens were recorded. The results showed that the average body length (SVL) of female individuals of Pelobates syriacus was higher than those in males, which was found to be statistically significant (P≤0.05). Meanwhile, the average body length (SVL) of female individuals of Bufo viridis was found to be higher than those in males, however, the difference was not statistically significant. No sexual dimorphism was detected in the second-to-fourth, second-to-third and third-to-fourth digit lengths ratios of left fore and hind limbs between the male and female undividuals of Bufo viridis. However, the second-to-fourth digit ratio (2D:4D) in Pelobates syriacus species were found to be significantly different (P=0.040) between the male and female individuals, as the ratio was higher in males than females. Therefore, it could be concluded that the sexual dimorphism in 2D:4D of Pelobates syriacus species is consistent with those in most amphibians and diapsids.

Finger length ratios are organized during embryonic development of fingers as they exposed to sex steroid hormones, and may show varying degrees of sexual dimorphism between males and females in different animal groups. Among all the finger length ratios calculated in a sample, the ratio between the second to fourth fingers (2D: 4D) is the most important one. In this study, the 2D:4D ratios in both sides of the body (right and left) in all limbs were investigated to determine if sexual dimorphism is present in the 2D: 4D ratios in 44 specimens studied (20 males and 24 females) of Acanthodactylus blanfordi. Other morphological traits of the two sexes were also examined (23 metric and meristic traits), as a result, sexual dimorphism was observed in five metric and meristic morphological traits. In terms of the ratio of the size of the fingers and toes, sexual dimorphism in the length of the fingers was observed only in 2D: 4D on the right side of the body in forelimbs and hindlimbs. The value of this trait was higher in males than females and this difference was statistically significant P ≤0.05).

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.

Abstract: Due to the presence of taxonomic ambiguity regarding Petroleuciscus ulanus and Alburnus atropatenae and the tendency to treat them as synonyms of each other, this study was conducted to validate these two species by comparing their morphometric and meristic characters in the Mahabad-Chai River, Urmia Lake basin. A total of 64 specimens of P. ulanus and 68 specimens of A. atropatenae were sampled and were then investigated for 17 morphometric and 7 meristic characters. Measurements were standardized to eliminate the effects of size due to allometric growth pattern, then their normality and abnormality were examined. Standardized data were analyzed using t-test, Mann-Whitney, principal component analysis (PCA) and discriminative function analysis based on P-value of Hotelling's t-test (DFA/Hotelling's T-test) methods. The results showed that the two species were significantly different in 11 morphometric and 2 meristic traits (P<0.05). DFA analysis also showed significance differences between the two studied species. Our results refute the synonymy hypothesis of Petroleuciscus ulanus and Alburnus atropatenae on the basis of morphometric and meristic traits. Therefore, based on the results of this study, the taxonomic identities of these two species are valid.

The status of sexual dimorphism patterns in human and various animal groups including some mammals, birds, reptiles and amphibians have been studied, however, despite the fact that a growing number of studies were aimed to describe sexual dimorphism patterns in external morphological features such as the proportion of toes in animals, our knowledge of some basic issues, specially in some animal groups, is still limited. In this study, sexual dimorphism in terms of external morphological features as well as the ratio between finger lengths II to IV (2D: 3D, 2D: 4D, 3D: 4D) of the front and rear limbs in 30 specimens of Bufo eichwaldi toads (15 male and 15 female specimens) were in northern Iran. The results showed that females had higher mean body length (SVL) than males and this difference was statistically significant (90.50 mm in males vs. 114.93 mm in females and P = 0.00). In terms of other morphological traits, the results of T-test analysis (T test for independent samples) showed that the traits of diameter between two eyes (IOD), tympanum diameter (TD), length of the humerus (LHU), forearm length (FOL) and foot length (FL) had significant differences (P ≤ 0.05) between males and females. Also, the ratio of the size of the length of the fingers and toes on the left side of the body was examined in the species studied in terms of 2D:3D, 2D:4D, 3D:4D. The results showed that males and females were significantly different in two traits including 4^th toe length (D4) and 1^st finger length (F1). In addition, in terms of 2D:4D between males (0.4628) and females (0.4853) significant difference (P = 0.041) in the second and fourth toes of the hind limbs and in terms of 3D:4D between males (0.6233) and females (0.6787), there was a significant difference (P= 0.040) in the third and fourth fingers of the hind limbs. In this study, some habitat characteristics, ecology, threats and conservation measures related to Talysh toad species were also investigated.

Cisplatin, as a chemotherapy drug, causes serious side effects in the advanced stages of the cancer. Recently, Artemisia has been considered for its bioactive compounds, anti-proliferative and anti-inflammatory effects. The aim of this study was to evaluate the anti-cancer and anti-metastatic effects of the methanolic extract of aerial organs of Artemisia and cisplatin, either alone or in combination, in human ovarian cancer cell line A2780. The viability of A2780 cells after treatment with Artemisia extract, cisplatin and their combination was evaluated by MTT assay and the alterations in the morphology of the cell nuclei were examined by DAPI staining. The induction of apoptosis was assessed by Annexin V test, cell migration and changes in expression levels of apoptotic genes (Bax and P53) and metastasis (MMP2 and MMP9) using real-time PCR. MTT test data showed that Artemisia extract, cisplatin and their combination decreased the viability of ovarian cancer cells. DAPI and Annexin V indicated the DNA fragmentation and increased percentage of cellular apoptosis in comparison with the control group. The migration and real-time PCR data showed a decline in thr cell invasion and expression of genes involved in metastasis (MMP2 and MMP9) in cancer cells while the expression of apoptotic genes (Bax and P53) was increased in the treated groups. The results of this study showed that while both Artemisia extract and cisplatin posses anti-proliferative effect, apoptotic and suitable anti-metastatic effects on their own in A2780 cell line, their combination have synergic effects and posses those desired properties in lower concentration of cisplatin, which can reduce the side effects of cisplatin in cancer treatment.

Molluscs are important pests of natural and agricultural ecosystems, by feeding on different parts of leaves, stems, flowers, buds, fruits and roots of different plant hosts, reducing the marketability of annual agricultural products and damage plant species in different habitats in the country. Moreover, they are intermediate hosts of human and cattle parasites, and therefore are of medicinal and veterinary importance. In this study, snails and slugs were sampled from nine designated stations located in the south and west regions of Tehran province, considering their natural condition, vegetation, location of gardens and fields, soil or subsoil types, from the beneath of rocks and trunks, water bodies and other areas related to the habitat of snails and slugs. Samples were made using sampling nets or gathered directly by hand from plants, shrubs and river banks. Overally, 17 species belonging to 12 genera from nine families were collected and identified. Identification was done according to morphometric characters including shape, size of shell, dextral and sinistral position of the shell, operculum, aperture, radula, mucus colour, respiratory pore, keel, renal ridge and reproduction system. The highest and lowest mollusc species diversity among the stations studied were turned to be 16 and 6 species belong to station 9 (west of Tehran province) and station 2 (south of Tehran province), respectively. The most commonly diversed family was Hellicidae with 5 species, i.e., Monacha cantiana, Euomphalia pisiformis, Helicella krynickii, Helicella derbentina, Caucasotachea atrolabiata. Also, Lymnaea truncatula is identified as the most frequent species, which has medical importance. Monacha cantiana was identified in the present study and reported for the first time from Iran. All the samples and their respective spatial and temporal information were made available in the museum of the Agricultural Zoology Research Department in Iranian Research Institute of Plant Protection.

Barnacles are bottom-dwelling crustaceans that live on a variety of substrates, including rocks, mollusk shells, corals, sponges, mangrove roots and leaves, and the body surface of turtles and whales. The present study deals with the species Microeuraphia permitini on the shores of Bandar Abbas in two stations of mangrove forest and rocky beach in a period of two months, and has investigated the morphometrics of the specimens, while considering the effect of the lunar cycle on reproduction, temperature and wind speed of the environment. Five longitudinal parameters (height, basal length and width, opercular length and width) were recorded. The results showed that 90% and 70% of the samples of both stations had eggs in the second day (new moon) and eighth days of lunar months, respectively, and in the twelfth day of the lunar month (full moon) all samples contained eggs. The results showed that there is a significant difference between the height and base length of the barnacle, but the difference between the opercular length, opercular width and base width is not significant. In addition, in both of mangrove and rocky stations, there was the highest correlation coefficient between opercular length and width (r=0.84 and r=0.78, respectively). The lowest correlation coefficient in mangrove station was between base length and opercular width (r=0.5) and in rocky station between height and base width (r=0.2). The wind pattern was variable during this period and the approximate decrease of the north wind was seen during the sampling period. Air temperature changes were seen between minimum 30 °C and maximum 39 °C. In addition to the tidal cycle, wind and temperature can affect the spawning of the species as an environmental stress factor.

The family Verbenaceae, currently consists of Verbena and Phyla genera in different parts of Iran, especially northern provinces. The frame of this family has undergone significant changes in comparison with the previous references. For example, Vitex and Clerodendrum have been defined as the genera of this family in previous references. Accordingly, in this study, the relationship among these four genera has been evaluated using morphological and leaf anatomical characters of 20 samples. For this purpose, 67 qualitative and quantitative morphological and anatomical traits were used. The analysis of data was performed using R software ver. 4.3.1. For simultaneous analysis of quantitative and qualitative data, Factor Analysis of Mixed Data (FAMD) method was applied. The results of this study indicate the high value of some quantitative traits such as main vein xylem length, seed width, style length and blade width and some qualitative traits such as blade epidermal cells shape, stomata position, two arms of blade position in relation to each other, indumentum type, main vein epidermal cells shape, petal color, blade vascular bundles number, density of indumentum, leaf margin shape and stem branches length in the clustering of the genera. Totally, Analysis of data led to the separation of these genera. In accordance with the phylogenetic studies, Vitex and Clerodendrum show more affinity to each other and are separated from the currently native members of Verbenaceae in Iran, i.e. Verbena and Phyla.
