Abstract

Knowledge of genome size is used in a wide variety of biological fields such as cell and molecular biology, ecology, phytogeography, systematics, development of genome sequencing projects and for comparative studies of genome structure and evolution as a key diversity characters. Orchidaceae is the most variable angiosperm family, with 168-fold differences in genome size. This research was begun because of a lack of DNA content data from a genus of terrestrial orchids, Cephalanthera, in Iran. To estimate the nuclear DNA content (2C value) of three species of Cephalanthera, a flow cytometric study was conducted with young and well-developed leaves of plants collected from their natural habitats in Gilan and Mazandaran provinces of Iran. The

Abstract

Developing scale-up system and automation of micropropagation in a bioreactor has been a possible way of cost reduction and intensive manual handling. We report a comparison between the results of experiments aimed at improving carnation micropropagation using new bioreactor according to Temporary Immersion Bioreactor (TIB) and solid culture. By applying different levels of BAP, at the concentration of 3 mg L− 1, we observed 14.3 new shoots in TIB, but the number of new shoots on solid medium reached to 5.7 at the same treatment. Our results also showed that with 3 mg L− 1 BAP in TIB, the initial fresh weight of plant material increased from 10 g to 450 g after 15 days. It is concluded that TIB showed more than 10 times shoot production

Abstract

Iran supports a great share of exotic and/or endemic plant genera and species. The genus Fritillaria (Liliaceae) is a precious part of this botanical richness with 19 species, of which 10 are endemic to the country. However, signs are mounting that the country is truly at a crossroads when it comes to preservation of this national wealth. In this regard, an effective conservation strategy should thoroughly consider the classification of Fritillaria, as conservation practices are compromised by knowledge gaps in systematics and taxonomy. As published studies on Fritillaria in Iran have been sporadic and limited in scope, the aim of this review is to provide information necessary to help bridge these information gaps. Our objective is to faci

Abstract

Nitric oxide (NO) has been found as an important growth regulator and posses much attention in different aspects of science, including medicine, biochemistry, physiology and genetics. NO enhances hormonal effects through cytokinen signal transduction in vitro. The stimulation effect of sodium nitroprusside (SNP) is by releasing NO during in vitro culture. In this experiment, the effect of NO on Gerbera micropropagation has been studied based on completely randomized design. Leaf explants were cultured on modified MS, containing 0. 5 mg/L 2, 4-D and different concentrations of SNP (0, 20, 40, 60, 80, μ M). In the second experiment, proliferation of shoot was studied on MS containing 0. 5 mg/l BAP+ 0. 1mg IAA and different concentrations of

Abstract

Five species (13 ecotypes) belonging to three subgenera of ornamental-medicinal Iranian Fritillaria were karyotypically studied, using a standard squash technique. All species were diploid (2n= 2x= 24) having mean chromosome lengths of 15.8 ?m (15.2–16.7 ?m). Their satellites varied in number (1–3 pairs) and in size (1.2–2.6 ?m), mostly being located on long arms. Four chromosome types (“m”,“sm”,“st”,“T”) formed 10 different karyotype formulas:“T” type chromosome is reported for the first time in most species (with the exception of S4, Fritillaria. reuteri Boissi). ANOVA confirmed significant intra-and inter-specific chromosomal variation across the Iranian Fritillaria species. Twelve different methods were used to

Abstract

The carnation (Dianthus caryophyllus) is one of the top-selling commercial cut-flower crops worldwide, which is very susceptible to infections. Micro propagation is an advanced biotechnological system for producing free of pathogen colonies. Too many factors may limit micro propagation of plants, which the most important of them is contamination (eg, fungal, bacterial and viral infections). There are some methods and chemicals which are available to control in vitro contaminations. However, the efficiency of some of these methods is low, and/or some of them are too toxic. Mercury chloride as an example is very effective, but it is very toxic. Nanotechnology is relevant to diverse fields of science and technology. Antimicrobial activity of s

Abstract

Fritillaria contains up to 160 taxa in the family Liliaceae, through which imperial crown (F. imperialis L.) is of high medicinal and ornamental values and importance. Nineteen ecotypes of the species were collected from their natural habitats grown in 6 provinces of Iran during spring, 2011. Phylogenetic analysis was performed based on DNA sequences of the internal transcribed spacer (ITS) region of the nuclear ribosomal cistron. The phylogeny was constructed using neighbor joining and maximum likelihood inference methods. The analysis revealed a fair feasibility of ITS region DNA sequence for phylogeny of F. imperialis L. Results showed that the examined samples were evidently diverged into 3 distinct clades. Although, two yellow-colored

Abstract

Chelidonium majus L. belonging to the Papaveraceae family, grows naturally in north of Iran with anti-cancer and anti-HIV properties because of isoquinoline alkaloids such as morphine, codeine, papaverine, thebaine and noscapine. The aim of this study was to quantify the amounts of the mentioned isoquinoline alkaloids in the samples collected from different altitudes of north of Iran, and investigate the effect of environmental factors on the amounts of these compounds. Therefore, five regions were selected including Mazandaran, Golestan, and Firoozkouh, and after quantitative measurements of alkaloids, the effect of altitude was also evaluated to determine its impact on the amount of these compounds. According to the obtained results, the

Abstract

Chromosomal and karyotype parameters and genome size were examined in 22 Iranian populations of nine different Tulipa species, using squash technique and 1?% (w/v) aceto-orcein stain. Flow cytometric studies were performed using PI staining method and Vicia faba cv. Inovec (2C DNA?=?26.9?pg) as a reference standard. Most species were diploid (2n?=?2x?=?24), having three chromosome types (“m”, “sm”, “st”). The chromosome length (TL) varied from 6.4?μm (S2) to 12.90?μm (S3). Total chromosome volume (TCV) ranged from 32.9?μm3 (S2) to 66.0?μm3 (S8). Statistical analyses confirmed more intraspecific chromosomal and genome size variations than interspecific.

Abstract

The genus Fritillaria (Liliaceae) embraces up to 165 species, including taxa of both medicinal and ornamental importance. In this study, 44 specimens of the genus representing 9 species were collected from their natural habitats located in 10 provinces of Iran. For the purpose of finding phytochemical diversity and a possible discriminant method among Fritillaria species, five major isosteroidal alkaloids (ISAs) of the genus (imperialine, verticine, verticinone, ebeiedine and ebeiedinone) were identified and characterized by gas chromatography (GC) and gas chromatography with mass spectrometry (GC–MS) methods. The estimated relative composition of ISAs was used to carry out a chemotaxonomic study on the species by means of hierarchical cl

Abstract

Choosing appropriate plants for urban landscapes is vital to avoid potential financial and environmental losses that may occur if all selection parameters are not taken into account. A methodology has been developed to assist landscape architects, planting designers, and urban horticulturists in the plant selection process. Tehran has been picked as a case study due to its arid and semi-arid climate which poses more challenges in front of an expert. After grouping plants, selection parameters have been defined for each plant group. Plant species were comparatively graded for each parameter by a group of eight specialists. Analytical hierarchy process (AHP) technique and hierarchical cluster analysis have been utilized to find the most adapt

Abstract

The genus Fritillaria embraces up to 165 taxa in the family Liliaceae, most of which are of high medicinal and ornamental value and importance. In this study, 44 specimens of the genus representing 9 species were collected from their natural habitats located in 10 provinces of Iran. Phylogenetic analysis was performed based on DNA sequences of the internal transcribed spacer (ITS) of the nuclear ribosomal cistron and the trnL-trnF regions. The phylogeny was constructed using the neighbor joining inference method. Results indicate that the examined samples were evidently diverged into 2 distinct clades. Members of the subgenera Fritillaria and Rhinopetalum formed one clade while the other clade contained the subgenera Theresia and Petilium.

Abstract

Leuzea (Rhaponticum carthamoides) is a valuable medicinal plant from Asteraceae. Micropropagation could be a good alternative for the mass propagation of Leuzea carthamoides. To investigate the callogenesis of leaf explants, 12 different hormonal combinations including different concentrations of 16-benzylaminopurine (BA) and 2,4-dichlorophenoxyacetic acid (2, 4-D) were studied in two separable experiments. In both experiments, the explants were transferred to the Ms medium supplemented with 0.5 mg L-1 indole acetic acid (IAA) and 0.5 mg L-1 BA for 7 and 50 days after culture for regeneration, respectively. Then, after one month the percentages of callogenesis and the amount of produced callus were measured. In other experiment to investiga
