This study investigated the variation in the pigment, proline, soluble sugar and ion content of three populations of Haloxylon ammodendron in Yazd province. This was carried out using one-year old plants of the same size from each population. Sampling occurred in a factorial experiment conducted using a randomized complete design with five replicates. The results showed that chlorophyll a and t...
Chickpea (Cicer arietinum L.) is one of the most important legume crops in Iran. Wilt disease caused by Fusarium oxysporum f. sp. ciceri, is the most important soil-borne disease of chickpea in the world. This disease caused high losses in different regions during recent years. Simple sequence repeat (SSR) were used to estimate genetic diversity in 114 of F. oxysporum isolates from six counties...
differentiation among populations of the iranian teucrium polium l.was analyzed on the basis of morphological and phytochemical variability, to evaluate the level and distribution of diversity among four distant populations from arid, semi-arid, and sub-humid regions of fars province. morphological analysis included 11 characters related to the plant, leaf, and stem morphology. analyses of vari...
Introduction: The emergence of single-cell RNA-sequencing (scRNA-seq) technology has provided new information about the structure of cells, and provided data with very high resolution of the expression of different genes for each cell at a single time. One of the main uses of scRNA-seq is data clustering based on expressed genes, which sometimes leads to the detection of rare cell populations. ...
anopheles fluviatilis complex is known to be a vector of malaria in iran. since mosquitoes of this species cover a wide geographical range in iran, they might have evolved into different separated populations. random amplified polymorphic dna polymerase chain reaction (rapd-pcr) assay was used to differentiate geographic populations of this species. dna was extracted from individual mosquitoes ...
Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...
Population structure of sea cucumber Holothuria parva in the coasts of Bushehr and Halileh from Persian Gulf was determined by 16S rRNA of mitochondrial genome sequencing in autumn and winter seasons of 2019. In Bushehr and Halileh populations, 2 and 4 haplotypes were identified out of 374 nucleotide sites, respectively, and haplotype 2 was the most abundant in Bushehr population and was observ...
Chamomile (Anthemis haussknechtii Boiss. & Reut. and Anthemis pseudocotula Boiss.) are annual, medicinal and aromatic plant belong to Asteraceae family. This two species have special important in pharmaceutical and cosmetic industries. Current study was carried out to investigation of different pre-treatments for enhancement of seed emergence potential, rate of emergence and v...
The genetic diversity of 20 Iranian populations of Bunium persicum has been evaluated with random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers. Fresh leaves of seedlings from each population were used for genomic DNA extraction. Analysis of banding patterns of 15 RAPD primers and 17 AFLP primer combinations, revealed 192 (86%) and 228 (75%) polymorp...
Elaeagnus angustifolia L. is a Eurasian tree that has become naturalized and has various ecological, medicinal and economical uses. In this study, a combination of morphological traits and RAPD markers were used to study the presence or absence of an association between genetic variation and morphological features among five populations of E. angustifolia collected from the East Azarbaijan of I...
